[00:00:23]So go right ahead, type hello in the chat. Now, as you are doing this, quickly get your pencil and your book because we're going to practice some grade four diagnostic, well, some grade for numerousy items together.

[00:00:41]Hello, Javante, Rafael, lovely Deandra.

[00:00:46]Hello to that writing, Jayla, Kyla, hello. Hello, Jesse. Welcome guys.

[00:00:53]Welcome to our lesson today.

[00:01:02]All right, welcome Belle Kyla.

[00:01:07]All right, now as we are here, I want you also to tell me what school you're joining from. I see Leon from Ensom City. Let me know what school you are joining us from.

[00:01:24]Go ahead and share that in the chat. Hi Adri. Hi Muik.

[00:01:32]Latana Mary Rashed. Very good. Okay. Welcome to Bethl Primary, Mount Nebo, Mona Heights Primary, Unity, Pemrook All Scots Pass, Port Antonio Primary. Welcome guys. This is lesson three. So if you're joining us for the first time, welcome Mandville. Make sure you hit that subscribe button so you know when we're going live again. Welcome Davis Primary.

[00:02:10]Balcom Drive Primary and make sure you share this live with your friends so that they too can benefit from what we are studying here.

[00:02:21]All right. So, as you are getting your pencils and your book ready and you're sharing with us which school you're joining from, we are going to go through some rapid response items and I'm looking for first correct answer in the chat. This is to get our brain juices flowing. So, let's go.

[00:02:42]What is 1,225 + 10?

[00:02:48]What is 1,225 + 10?

[00:02:56]Let me see your answers in the chat.

[00:02:58]Welcome, Mona Prep, Mount Morland. Welcome. All right, Jayla and Lincoln. First one says 1,235.

[00:03:11]Leon says 1,235.

[00:03:14]Good job, guys. Very good. Next one.

[00:03:19]What is 1,360 take away 20?

[00:03:26]What is 1,360 take away 20?

[00:03:32]First correct answer in the chat. Let's go.

[00:03:40]All right, someone. Okay, Jayla says 1,340.

[00:03:46]Lincoln says 1,340.

[00:03:49]Adri says the same thing. Leon says the same thing. Good job. Yes, you are correct. The correct answer is 1,340.

[00:03:58]What is 15 * 4? What is 15 * 4?

[00:04:05]Let's see your answers here in the chat.

[00:04:09]And I'm seeing some persons that I had in my last class. Welcome.

[00:04:14]It's great to have you again today.

[00:04:19]All right.

[00:04:21]Joan says 60. Lincoln says 60. Leon Diane Elite Pro. Yes, you are correct.

[00:04:29]It is 60. 15 * 4 is 60. What number comes next? 40 55 70. What number comes next? 40 55 70. Tell us what number comes next.

[00:04:48]First correct answer in the chat.

[00:04:55]All right, Jayla says 85. Good job.

[00:04:59]That's the first correct answer.

[00:05:02]All right, great work. I see Jesse saying 85 as well and Richard Leon Latan. Okay, not Latana, Joan. All right, very good, boys and girls.

[00:05:17]What is half of 18?

[00:05:20]What is half of 18?

[00:05:27]Let's do it. What is half of 18?

[00:05:33]All right, first one.

[00:05:36]Diane says nine.

[00:05:39]Leon says nine. Jesse, Jayla, Diane, Maverick, Lincoln, excellent work. Half of 18 is nine. Now, I see that our brain juices are flowing. We can get right into it. So, let's go to our first question.

[00:05:57]Jake is using tape to mark out the perimeter of this net ball court.

[00:06:04]How much tape does Jake need to mark out the perimeter?

[00:06:10]If you're joining us for the first time, welcome, welcome, welcome.

[00:06:17]Don't forget to subscribe or like or even share this with your friends so they can also practice with us.

[00:06:30]So Jake is marking out the perimeter of this net ball court. How much tape does he need?

[00:06:50]Let's see some answers here. Persons are saying 20 m.

[00:06:55]24 m.

[00:06:58]I'm seeing many different responses here, but this only tells me that people are thinking. Remember, when you're writing your answer, boys and girls, you must put that unit. All right. Now, Ellen Morgan is explaining for us what's happening. She says the perimeter is when you multiply the length by the width. So, the perimeter is 24. Think about it.

[00:07:20]Think about the perimeter, Ellen. I think you're mixing this up with area.

[00:07:27]So let's talk about it. What is the parameter students?

[00:07:33]What's the parameter?

[00:07:36]What does perimeter mean? Jayla is saying 6 + 6 + 4 + 4 = 20.

[00:07:43]What when we talk about perimeter, what are we talking about?

[00:07:51]Leon says permit is a total distance around. Excellent. So, we're talking about the total distance around this net ball court.

[00:08:01]And how do we do that? Someone says we need to add all the sides. Joan says we need to add all the sides. And that is correct. So, since it's a rectangle, as you can see here, we know even the missing sides, we know what they measure. If this part is 6 m, that means right here must be what?

[00:08:24]Because in order to now add these sides, we need to know what the missing sides are measured. So if up here is 6 m, what is the opposite length?

[00:08:39]All right, I see Rain and Leon saying 6 m and Brooklyn saying 6 m. Correct. Now we have the measurement for here 4 m. What would be the length for this side?

[00:08:54]Let's see your responses here in the chat.

[00:08:58]And I want when you get a question like this, you go ahead and you can write out the missing sides like this. Helps you greatly. Okay. Rashane says this side is 4 m. Now that we have the length of all four sides, we can now find the perimeter. And someone said we need to add the length of all the sides. So here we have 6 m plus 4 m + 6 m + 4 m.

[00:09:37]And that would be equal to 6 + 4 is equal to 6 + 4 is equal to 10 + 6 = to 16 + 4 equals to 20. So our answer will have to be 20 m. When we add this 20 m is what we will get for adding all the sides.

[00:10:11]Great job guys. And guys do not leave your unit off. You need to write meters on it. Next question.

[00:10:20]There is 600 ml of juice in Ryan's glass.

[00:10:26]This is Ryan's glass.

[00:10:29]Now it says here about how much juice is in Pat's glass?

[00:10:34]So it tells us how much milll of juice in Ryan's glass and we should use that information to now see how how how much milliliter in Pat's glass.

[00:10:48]All right. So tell me the answer and how did you get it?

[00:10:56]Tell me the answer and how did you get it?

[00:11:01]All right. So, let's see. I'm looking for some explanations here.

[00:11:19]Elite Pro says it's half.

[00:11:24]All right. Leon says it looks like half of Ryan's juice.

[00:11:30]All right. Yes, we can use estimation.

[00:11:34]And students, if you are calling, do not call. I'm on live. Your number will now be shown to the world if you're supposed to call while I'm teaching online.

[00:11:44]All right. Now, here it shows that this is about half of Ryan's juice.

[00:11:52]That's what someone said. So if Ryan's juice is 600 ml half of 600 ml would be I'm seeing many people explaining here and Obaka says if you look it is half and half of 600 is 300 ml. Okay. So, you're Messiah. Thank you for telling me that, Messiah. All right.

[00:12:15]So, let's think about it. Half of 600 ml would be 300 ml. And if that's your answer, very good.

[00:12:26]Great work.

[00:12:30]Now, let's go to our next question.

[00:12:35]Which would you measure in kilometers?

[00:12:39]The distance a car travels in two hours.

[00:12:42]The length of the blackboard in your class. The width of the doorway of your classroom. How high you can jump. Which would you measure in kilometers? What do we normally measure in kilometers? By the way, let me see your answer in the chat.

[00:13:03]Lincoln says the distance a car travels in two hours.

[00:13:10]All right, let's see. Brooklyn is saying the same thing.

[00:13:18]Someone says the road. Jordan says distance. Yes, we use kilometers to measure distance.

[00:13:26]Kilometer used for road. All right. Now kilometers because we know it's a unit used to measure long distances.

[00:13:35]Then it says a the distance a car travels in 2 hours. The length of the blackboard in your class. Why would we use kilometers? Kilome is so big.

[00:13:46]So of course we will not be using kilometers to measure that. If it's not distance we're measuring. It's not road kilometers will not be used. the width of the doorway of your classroom.

[00:13:58]That's about as wide as you are if you stretch one arm out. So that can't be kilometers. How high you can jump.

[00:14:06]Again, that won't be kilometers. Just remember that kilometers is used to measure distance. It's used to measure road. All right. So if you said a, good job.

[00:14:20]Good job. Let's go to our next question.

[00:14:24]How many sides does an octagon have? How many sides?

[00:14:34]Yes, Zena, you are correct. Very good with that explanation.

[00:14:42]All right. How many sides? Wow, I see people saying eight sides. Many of you are saying eight sides. You know your shapes. Very good. Octagon. Oct means eight.

[00:14:54]So an octagon here is one has eight sides. This is an octagon has 1 2 3 4 5 6 7 eight sides. So if you said eight, you are correct. Good job. Shane Kelsey, I'm seeing you also seeing eight.

[00:15:17]Octagon.

[00:15:19]All right. Well done, boys and girls.

[00:15:23]What two polygons are in this shape?

[00:15:26]Let's take a look. What two polygons are in this shape?

[00:15:36]Let me hear from you.

[00:15:39]Yes, Diane, you are correct.

[00:15:43]What two polygons are here?

[00:15:46]Go ahead and write those out in the chat.

[00:15:49]Latana says a rectangle and the triangle.

[00:15:54]Okay. Leon says rectangle and triangle.

[00:15:57]Anisha Ladisha saying the same thing.

[00:15:59]Joan saying the same thing.

[00:16:05]All right.

[00:16:09]All right. Jordane sing triangle and rectangle. So it's Omar Ming rectangle and triangle. Brooklyn is also saying the same thing.

[00:16:19]All right, Latia. All right, Desireine.

[00:16:23]Okay, very good. So, I see that we are thinking alike because here we have a rectangle.

[00:16:34]That's one polygon. And we know that a polygon is a closed shape, right? And here we also have a triangle.

[00:16:44]So, A says two triangles. Clearly that's not so. B says two quadrilaterals. And what are quadrilaterals?

[00:16:54]What's a quadrilateral? How many sides do quadrilaterals have?

[00:17:03]Quadrilaterals have four sides. And of course, if one has four and the other one has three, cannot be two quadrilaterals.

[00:17:11]Great work, guys. A square and a rectangle. Hm. This has two long sides and two short sides. So that's definitely not a square. All right. So this is not correct. A rectangle and a triangle. Here we have our rectangle.

[00:17:28]Two long sides, two short sides, or two pairs of parallel um sides. All right.

[00:17:34]So if you said a rectangle and a triangle, good job.

[00:17:40]Good job.

[00:17:45]All right. Now, guys, I am seeing all of your responses. Some of them are coming so fast. So, if I don't see your name to call your response out, bear with me because when many people are typing their responses, I won't be able to see or read them all. Okay? Please understand. But I try my best to acknowledge and recognize everyone who are participating. Let's go to our next question.

[00:18:14]How many triangles are in this set of shape? Triangles. What are triangles?

[00:18:20]How will we figure out which ones are triangles?

[00:18:24]How many triangles are in this set of shapes?

[00:18:36]Let's see.

[00:18:37]Someone says two.

[00:18:41]I'm seeing many two. I see people saying three as well. Some persons are even saying four.

[00:18:50]All right. How do we identify triangles?

[00:18:52]Someone says the ones with the three sides. Let me see who said this.

[00:18:58]Desireine says the ones with the three sides. You are correct. Triangles. They have three sides. So, let's go and see which ones have three sides here. 1 2 3.

[00:19:09]That is one with three sides. One, two, three, four, five, six. This doesn't have three sides. One, two, three, four.

[00:19:17]Does not have three sides. One, two, three. Another one with three sides.

[00:19:23]One, two, three, four. Doesn't have three sides. So, if you said two, you are on the ball. Excellent work.

[00:19:33]Good job.

[00:19:36]Let's look at our next question.

[00:19:38]Which street is parallel to Canary Street? Let's take a look at this map and let's think about it. What do we when we say parallel, what do we mean?

[00:19:49]What are parallel lines? What does parallel mean? Let me see that in the chat. Let's some I want someone to explain what does parallel mean.

[00:20:08]All right. So, let me see here. Someone says straight, but is that really so?

[00:20:14]Anisha says they don't meet. But what else can we say about parallel lines?

[00:20:21]All right. Ladisha says parallel means they do not meet. Okay. Quick sky says when they go across.

[00:20:30]Omar says parallel means straight.

[00:20:33]Shanoya says runs in the same direction and Brooklyn says they never meet. So I want to use those two responses to tell you or to just pin down what parallel lines are. Parallel lines are lines that run in the same direction like this and they will never meet. So once they run in the same direction like this, they will never meet. Just like in a in a rectangle, these two are parallel. They will never meet. As well as these two are parallel with each other. Those also will never meet. All right. So now we're thinking about this question. Which street is parallel to Canary Street? Let's think about where Canary Street is.

[00:21:30]Here is Canary Street.

[00:21:33]So, which street is parallel to this?

[00:21:37]Yes, Rashida. Parallel lines, they never stop.

[00:21:41]All right. Okay. Jord Jordan says Hummingbird.

[00:21:46]Elite Pro. Oh, Nathan says Hummingbird Street.

[00:21:51]Elijah says Hummingbird Street. All right, guys. And I'm seeing lots of others saying Hummingbird Street, of course. Let's take a look. They're running in the same direction.

[00:22:05]And of course, they will never meet. So, if you said Hummingbird Street, you are correct. Now, someone says Pelican Street. Now, if you're thinking about parallel lines, if this is, let me get another color here.

[00:22:20]If this is Canary Street and this is Pelican, you see that they meet right here.

[00:22:28]when they can meet and form an L like that, they're perpendicular.

[00:22:34]Okay? So, we're looking for parallel lines. So, Pelican is not parallel to Canary.

[00:22:41]Let's go to our next question.

[00:22:44]All right. So, now let's look at this map again. It says, which of the following pairs of streets are perpendicular to each other? Apparently, maybe I've given the answer already. I don't know but tell me which of the following pairs of streets are perpendicular to each other.

[00:23:06]All right.

[00:23:08]So I just said for you that parallel lines perpendicular lines they form an L maybe a T but basically they meet to make a right to form a right angle. So that's basically what perpendicular lines are. So tell me which pairs are perpendicular. Tell me the pair of streets that are perpendicular.

[00:23:34]Brooklyn says Dove and Raven Street.

[00:23:38]Let me hear what others are saying.

[00:23:43]Yes, Ellen Morgan. Very good for that explanation for the perpendicular.

[00:23:50]All right, let me see. So, all right.

[00:23:53]Jordan is saying canary pelican as well.

[00:23:56]Now let's take a look. Here we have pelican. Here we have canary. Yes, they form a right angle. Those are perpendicular.

[00:24:07]Let's see if we have any others. We have pelican again. Let me get another color.

[00:24:12]We have pelican also perpendicular to hummingbird cuz here again they form a right angle. Now let's see which of these are in the answers that we have. Canary and raven.

[00:24:26]Canary and raven. No.

[00:24:29]Dove and raven.

[00:24:32]Dove and raven. This is not a right angle. So no.

[00:24:38]Canary and pelican. So we did canary pel. Pelican. That looks good.

[00:24:44]Hummingbird and raven.

[00:24:47]No, this does not form a right angle. So the correct answer is Canary Street and Pelican Street. Key to note is that if they make an L, straight L or even a T with straight lines, you can see some perpendicular lines there. They must intersect, but when they intersect, they must form a right angle.

[00:25:14]Let's go to our next question. I know you have your pencils and your book out.

[00:25:18]So, let's work on this. What is 2,396 take away 1,79?

[00:25:27]Let's set that out in your book.

[00:25:30]2,396 take away 1,79.

[00:25:39]Some of you are solving this so quickly.

[00:25:43]No, Anisha, right angle measures 90°.

[00:25:50]Make sure you're solving this in your book.

[00:25:54]You're also going to solve this with me.

[00:25:58]All right, so let's see some answers in the chat.

[00:26:04]Leon says 687.

[00:26:08]Asher says, 1493.

[00:26:12]Zena says 687.

[00:26:15]Jordan says 687 as well.

[00:26:19]All right. So, let's do this one together. Let's do it together. Now, we're subtracting. I see Anmarie saying 69. Okay. I think that's an error. All right. Now, here we have nine 1's. We're taking that from six ones. Remember that rule. More on the floor go next door.

[00:26:37]The floor is the lower number. So we have more at the bottom which is more on the floor. So we have to now go to the next place to do some regrouping. 1 10 from 9 10 will leave 8 10. And that 1 10 and this 6 1's will now give us 16 1's.

[00:26:55]So 16 take away 9 is what? Help me out there in the chat. What is 16 take away 9?

[00:27:08]16 take away 9 is Thank you. Thank you, Leon. That's seven. Now, if you look at the answers, basically you know your answer already, right? If you look at the options that you need to choose from, you know your answer already. But let's continue. 0 from 8 will be 8 take away 0. What is your difference?

[00:27:34]8 takeway 0 is 8. Thank you.

[00:27:39]3 take away 7. We can't because we have more on the floor. So, let's go next door. So, we take 1,000 from 2,000. We have 1,000 left. We add that 1,000 to this 300s. Now, we have 1300s. 1300s take away 700s is what? What is 13 take away 7?

[00:28:02]13 take away 7 that would be six.

[00:28:07]And then 1,000 from 1,000 that's zero.

[00:28:10]So we leave it as is. So if your answer was 687, good job.

[00:28:21]Let's go to our next question. Great work. What is 2045 written in expanded form?

[00:28:29]Let's see that in the chat. What is written in expanded form? All right.

[00:28:47]So, I'm looking for some expanded form answers in the chat.

[00:28:55]All right. So, I am seeing Okay, I think I missed that one.

[00:29:04]Let me see some answers here. I see Sophia saying 20,000 + 40 + 5. Laren is saying the same thing. And Brooklyn Omar King is saying the same thing as well.

[00:29:18]All right. And James saying the same thing. Alexander apparently we're all saying the same thing. Joan, Nico. Okay. I think we're Ladisha. We're seeing the same thing. Jordan.

[00:29:34]All right. Now, let's take a look here.

[00:29:37]Now, when we're looking at expanded form, let's think about the place value.

[00:29:42]I always want you to bear in mind the place value. So with 24,45 we have five 1's we have four tens we have zero hunds we have two thousands.

[00:30:04]All right let me just write it over here. Thousands 100 tens and ones we have five ones four tens. 0s and 2,000. All right. 245.

[00:30:20]So here we have 2 * 1,000 to give us 2,000.

[00:30:27]So that would be 2,00 plus 0 * 100 would be 0. So we don't need to write that here. We would leave that space empty. In the 10, we have 4 * 10. That would be 40.

[00:30:44]and in the ones 5 * 1 would be 5. So if your answer is 2,00 + 40 + 5, you did well. Good job. And for those who didn't get this on the get- go, I hope you now understand how to do expanded form. Great work.

[00:31:05]If you're enjoying this session so far, let's go ahead put some thumbs up, some hearts in the chat so I know that I'm not leaving anyone behind and we're all following.

[00:31:15]Okay, let me see those in the chat.

[00:31:21]Great job for those who got it.

[00:31:24]For the ones who tried but you didn't quite get it, you can always look back to see how to get this. All right, excellent work guys. All right, lovely to see those, let's go to our next question.

[00:31:41]Well, before our next question, I want to tell you about classes that will run from June 1 to June 20 to help you to prepare for this numerousy exam. And of course, if you your parents are interested, they can scan this QR code that is on my screen with their phone and they can register for you and I will send follow-up information there. Okay? And of course, if this is going to move too fast, you can always take a screenshot of this so you can look at it later. Okay? Now, I want to ask you a question. Would you rather to get $1,000 every week or a lifetime supply of pizza? Tell me what do you think and why? So, we're just halfway in our practice today. We will continue with our next question after, but I want you to tell me, would you rather to get a,000 every week or a lifetime of pizza? I see Latana says a lifetime of pizza. But why? Anisha says $1,000.

[00:32:53]Jordine says $1,000. Latan is saying lifetime of pizza. Raphael says $1,000 per week. Why?

[00:33:04]Let me see.

[00:33:06]Let me see why you Okay. Harry says pizza because he loves it.

[00:33:11]All right.

[00:33:15]Let me see what others are saying.

[00:33:18]Leon says he can put it in his account and use it for investment. Wow. You know what? I think you boys and girls will be some excellent adults in the future. I love the way you're thinking. Very important. Saving is important. But pizza, pizza is so unhealthy, isn't it?

[00:33:36]Well, you can get healthy versions, but majority are unhealthy. But if you choose pizza, that's you. For me, I would choose that $1,000 per week and I'll save it. And as you said, we can invest it. All right.

[00:33:51]Now, someone says to give their mom so they can start saving for their birthday. All right. Let's get into our next question. Lovely to hear your thoughts, guys. Which number Which number has the greatest value? Let's take a look at these numbers.

[00:34:10]Which number has the greatest value?

[00:34:22]Let's see.

[00:34:24]Bruce says a 450.

[00:34:28]Nadine is saying the same thing.

[00:34:32]Sharita saying the same thing.

[00:34:36]Ellen says 0.05.

[00:34:38]5.

[00:34:41]Jesse says 4.45.

[00:34:44]And uh Baka, what was her name again? I don't remember, but he also says 450.

[00:34:53]All right. Quickslay is saying the same thing. Brooklyn. All right. So, someone says Latana says 0.45.

[00:35:00]Now, remember, we're looking for the greatest value.

[00:35:04]Greatest value. Now, if you take a look at these numbers here, we have the ones place, then we have our decimal point, then we have the tenth's place.

[00:35:18]I'll put it like this, the 10th's place, then we have the hundreds place.

[00:35:30]And so we can now put these in order to see what is what. We can see which one has the greatest value. A says 4 1's 5.

[00:35:43]B 4 1's. 05.

[00:35:46]C is 0.54 and D is 0.45.

[00:35:54]Now in order to find the number with the greatest value, we have to look for the largest place value. And in this case it is ones because once you get into tths and hundreds those are less than one. So the greatest place value here is ones.

[00:36:09]If you look in ones we have four here and we have four here. These are zero.

[00:36:14]So clearly these are too small. We're looking for the greatest value.

[00:36:20]Since these two numbers have four in the ones place. Let's go to the next place value to compare.

[00:36:27]The next place value has five in the tenth's place for this one and zero in the 10th's place for this one. Five is greater than zero. And so this number is the greatest of them all. So if you said 450, way to go. You are doing well. Good job.

[00:36:52]Let's go to our next question.

[00:36:56]8.6 + 7.54 + 9.38.

[00:37:02]What is that equal to?

[00:37:05]Equals to unknown. Let's solve this one.

[00:37:09]Let me see your answer in the chat.

[00:37:14]Use your pencil. Use your book. In your exam, you'll need those.

[00:37:19]So, use your pencil and your book to solve.

[00:37:23]Interesting that some of you are are answering this even before my brain can turn on for it.

[00:37:29]So, let us put that out. Let's set it out properly so we can add. Jesse James says 24.42.

[00:37:38]Raphael says 17.78.

[00:37:42]Leon says 25.52.

[00:37:44]Ellen is saying the same thing. And Bruce.

[00:37:48]All right. Latana says 17.78.

[00:37:52]Omar Ming says 24.42. So I'm seeing many different responses here. Tiana saying 24.42. Latana 17.78. Let's work this out together.

[00:38:06]All right. So here we are going to set them out. So we have 8.6 7.54.

[00:38:17]Let's put a placeholder here of zero for that one. 9.38 and let's now add.

[00:38:28]All right. So when we're adding remember and even subtracting the points must align. So wherever we have the point here it will align even in our answer.

[00:38:41]So 800s + 400s give us what? What is 8 + 4?

[00:38:50]8 + 4 is 12.

[00:38:56]So let us rename it two in the hundred's place and one in the 10th's place.

[00:39:05]Now 3 + 5 is 3 + 5 is 8. 8 + 6 plus the little one.

[00:39:20]So 8 + 6 is 14 and the little one 15.

[00:39:26]Let's now re re regroup that. So we have five in the 10's place and we have one in the ones place.

[00:39:34]Now let us add these numbers in the ones place. 9 + 7 is 9 + 7.

[00:39:45]9 + 7 is 16. 16 + 8.

[00:39:53]16 + 8 is 24 plus the little one, that would be 25.

[00:40:04]So if you got 25.52, you are correct. 25 and 5200s. Very good.

[00:40:16]All right. Good job. And guys, remember when you get questions like this, just set them out and work them. Okay? And leave your workout next to your problem when you're submitting your paper as well. Leave your work out there. All right? That is encouraged. Now, what is the result of 621 * 6? Work this out. Get your pencil. Get your book. Set this out and work it out.

[00:40:43]All right. 621 * 6. Let me see your answer in the chat.

[00:40:55]Let me see your answer in the chat.

[00:40:57]Okay, Roma, I can see you working out our previous question.

[00:41:04]I see Jayla saying 3,726 and Ellen is saying the same thing.

[00:41:16]Kyle is saying the same thing as well as Elite Pro Vivine. All right, Jesse James. Okay.

[00:41:25]All right. Well, let's work this out together then. I see many people saying 3,726.

[00:41:31]You may be right, but I don't know yet until we work this out. So 6 * 1 6 * 1 is help me out here in the chat.

[00:41:43]6 * 1 is is 6.

[00:41:50]Now 6 * 2 6 * 2 is 12. We re regroup this so it will be two 10 100s. Now 6 * 3 I mean 6 * 6 is plus the little one. 6 * 6 plus that little one is thank you Bruce 37. 6 * 6 is 36 + 137.

[00:42:23]So, yes, 3,726.

[00:42:28]You guys were correct. Excellent work, guys.

[00:42:32]Excellent work.

[00:42:34]All right, let's now get to the next question. Which number sentence is true?

[00:42:41]H, let's see your answers in the chat.

[00:42:44]Which number sentence is true?

[00:42:52]Okay, I'll be looking for your responses here and you can also give me a little explanation as well so I know how you came up with your answer.

[00:43:10]Okay, I'm looking for your answer in the chat.

[00:43:17]I see Bruce is saying 1,5 no 15,321 is greater than 15,325.

[00:43:29]H take a look at this.

[00:43:35]Zane Zena is saying okay let's see what Zana was saying. Okay.

[00:43:50]All right. So Zena I've missed your response. Okay. 16, 163,46 is less than 163,511.

[00:44:06]All right, I'm seeing Ellen Morgan saying the same thing. And Brandon Bran is explaining that the alligator mouth always open to the bigger number. I love that. That's what we're going to work on here. So yes, the alligator mouth.

[00:44:21]Nadine is also saying the same thing.

[00:44:23]opens to the bigger number. So if you have that in mind, you know that if this is the alligator mouth, the bigger number will be on that side. The smaller number will not be. It will be on the opposite side. So this is an example of using the alligator mouth strategy. All right. Now let's take a look at a. Let's look at the largest place value. We have hundreds.

[00:44:49]So we have 9 hundreds here. 900s here same. So let's go to the 10 zero and n and seven. So this is greater than this.

[00:45:00]But this sign is saying that 97 is greater than. So A cannot be correct.

[00:45:05]Let's take a look at B.

[00:45:08]7,800 is equal to 780.

[00:45:11]Obviously that is not correct. Let's look at C. 15,321 is greater than 15,325.

[00:45:20]Let's look at the place value to figure this out. In the 10,000 place value, we have one. Those are the same. So, let's go to the thousand's place. Five. Those are the same.

[00:45:32]Let's go to the next one. Three. Those are the same. To the 10, two, those are the same. So, I guess the deal breaker is the one. We have to use that to determine which is greater. One in this number, five in this number. one is not greater than five. So this one has to be incorrect because it's saying that this is greater. So C cannot be correct. But let's look at D. Let's look at the place values starting from the largest place.

[00:46:04]100,000 same 10,000 same,000 is the same 100. Let's look at the hundreds now. Those are different. So the sign is turning this way. That means this number has to be greater. Let's see if that is correct. We have four in this hundred's place and five in this one h 100red's place. So yes, five is greater than four. So the sign is turned properly.

[00:46:33]Your correct answer is D.

[00:46:36]All right, for those who didn't get this straight off the bat, I hope you understand now. And for those who did, great work.

[00:46:44]Let's get to our next question. This one is division. It says to divide 2472 by 4. Set it out as well on your book.

[00:46:56]Tell me what answer you got.

[00:47:07]Now it can be you can use long division, short division. Which one is comfortable for you? No problem.

[00:47:16]So let me see some answers coming in after you have worked it out.

[00:47:27]All right, let's see some responses.

[00:47:39]All right, I'm seeing Rafael, Leon, Diane saying 618.

[00:47:45]Raheem is also saying 618.

[00:47:48]All right, Jordane Terry saying 618.

[00:47:54]Many people are saying 618.

[00:47:57]All right, let's see if I have any other response here. All right, so let's see if 618 is indeed correct.

[00:48:06]I'm not seeing anyone giving another answer which is good. That means most likely we're also we're also correct. I see someone saying 610.

[00:48:21]So let's see then. All right. So 4 into two goes zero times. So we can put zero if we want or we leave it blank. So since it goes zero times now we use these two numbers together. they will be 24. I see elite pro Nathan is explaining that beautifully there in the chat. If you can read his explanation that is explaining it well. 4 into 24 goes six times.

[00:48:50]4 into So we go to the next one now. 4 into 7 goes 4 into 7 4 into 7 goes one time and do we have a remainder?

[00:49:12]So we have a remainder of three. So we put three next to this two and make it 32.

[00:49:22]All right. So, three 4 into 32 goes how many times? Thank you, Leon.

[00:49:30]4 into 32 goes how many times? How many groups of four can you get from 32?

[00:49:39]Thank you. We can get eight. Thank you, Leon.

[00:49:44]Eight. That will make our answer be 618.

[00:49:48]And as I said before, we don't even need this zero. But if you need it to just keep us a placeholder when you're solving it, no problem. So if you said 618, you are correct. And guess what?

[00:50:01]This is just the short division way, guys. If you are most comfortable with long division, you can also do that. All right, so good job.

[00:50:15]Let's go to our next question. And we're almost at the end. So this question now it gives you a number but one digit is missing but that number when you multiply it by four you will get 944.

[00:50:34]What will this number be? Let's see what should be in the box. What digits should replace the box? Tell me how you got this. For this one I'm going to wait.

[00:50:45]I'm going to go slowly and I'm going to look for your responses in the chat.

[00:50:52]So, I want to see some explanations. I'm looking in the chat because I want to see that.

[00:50:59]All right. I see person saying one and four, but I want an explanation for this.

[00:51:08]So, let me see.

[00:51:11]How did you get this answer?

[00:51:14]How could you solve it?

[00:51:19]4 * 1.

[00:51:22]Are you sure? So, you're saying that we should put one here?

[00:51:27]All right. Well, let's test that.

[00:51:30]Let's test that out. And guys, I want you to test every answer you think of when you're in your exam. Let's test this out. So, if we have 231 * 4, you said 1. Let's see if we're going to get 944.

[00:51:45]4 * 1 is what is 4 * 1?

[00:51:54]That's four. And I saw someone ex said something about dividing 944 by 4. I want to remember that comment for when we're finished with this. So 4 * 4 is 1.

[00:52:06]4 * 3 is 4 * 3 is that's 12.

[00:52:19]Let's bring up that little one. 4 * 2 is 4 * 2 is 8 + 1 that's 9. And as you can see this is not equal to 944.

[00:52:34]So definitely one cannot be your answer.

[00:52:39]one cannot be your answer. But someone said we can divide 944 by 4. That's the easiest and the best way. That's what Marco is also saying here. That's the easiest and the best way. So let us start with that root. All right. So let us go and divide because when we are when we multiply the opposite of multiplication is division. We call it inverse operation. Okay. So if you multiply to get an answer if you divide this by the answer in the answer then you will get the next number that you multiplied by. So let us do our division 944ide by 4. Let's see.

[00:53:31]4 into 9 goes. Help me out here.

[00:53:38]So, I'm happy that I put an x on this one because it is definitely not correct. So, don't just look at it and say, okay, 4 * 1 is four, but what about the other digits? So, 4 into 9 goes two times. Do we have a remainder?

[00:53:57]two times remainder one. We put that one right next to the four. And now this becomes 14.

[00:54:06]4 into 14 goes.

[00:54:11]Tell me 4 into 14 goes. Tell me what it is. And if there's a remainder, tell me what that is, too. 4 into 14.

[00:54:23]Okay, let's see that.

[00:54:28]Yes, I see three times. Is there a remainder?

[00:54:35]Leon says 12 remainder 2. Think about it. 4 into 14 goes. Ellen says 3 * remainder 1. Think about that.

[00:54:44]4 into 14.

[00:54:49]How many times and what's the remainder if there are if there's a remainder?

[00:54:56]I'm waiting for that response in the chat. All right. Leon says three times remainder 2.

[00:55:05]Now we have this is 24. 4 into 24 goes.

[00:55:13]What is 4 into 24?

[00:55:22]4 into 24 is six and there is no remainder.

[00:55:30]All right. So here you can see we have 236.

[00:55:34]If we multiply this by 4, we will get 944. So your missing digit is is six. Excellent work. And we can double check to make sure we're correct.

[00:55:47]So we can multiply 236 * 6 sorry * 4 and see if we come with our answer.

[00:56:04]4 * 6 is 4 * 6 is 24.

[00:56:13]4 * 3 is 12 + 2 that's 14.

[00:56:25]4 * 2 8 + 1 that's 9. And as you can see we come back with our answer. Always remember to work backwards or double check and make sure that your answer is correct. Good job. Thank you guys for sharing and thank you for helping me with this multiplication and division problem. Excellent work.

[00:56:50]Next question. What digit is in the thousand's place in 48,000 130? Which digit is in the thousand's place? I know this one is just a piece of cake for you guys.

[00:57:05]So, let's see it in the chat.

[00:57:08]Thousand's place. What digit is there?

[00:57:12]All right, I see lots of persons saying eight, some persons saying four, some person saying one.

[00:57:20]Let's see. So here we have ones, tens, hundreds, thousands, 10 thousands.

[00:57:33]So in the thousand's place, we have the digit 8.

[00:57:38]Good job, guys. Awesome work.

[00:57:44]Next question says, in a race with six contestants, exactly two persons crossed the finish line after Omar. How much did Omar place in the race?

[00:57:58]So, in a race with six contestants, exactly two persons crossed the finish line after Omar.

[00:58:07]So let's think about it like this.

[00:58:13]Six people are in this race.

[00:58:22]All right. Six people are in this race.

[00:58:24]Let's see.

[00:58:27]Okay. I see person saying fourth. Some Dian saying third.

[00:58:33]Hodgej saying third. Kylie. Kyle is saying fourth. See many Judith saying third. Zay is saying third. Lisia saying third. But let's check it out. Now your answers must be written in ordinal number form. Latana saying fourth. Can't be two. Can't be three. Can't be four.

[00:58:55]Can't be six. You have to say second or third or fourth or fifth. It's a race we're talking about. So if six people are in the race here.

[00:59:05]So we have one one person here two person who came second person who came third fourth fifth and sixth. Now remember that crossing the finish line when Omar crossed there were two people who crossed after him. That means those two people came at the end right? Not at the end but he came before two people.

[00:59:33]So let's think about it from the sixth position. Someone crossed here here. These are the two people who crossed after him. So the two people who crossed after him after him, one came six, one came fifth. So Omar would have come in fourth.

[00:59:57]It's okay to even draw this out in your exam to make sure you understand. So here is Omar and these are the two people one two who came in after him. They finished after him. Someone came first, second, third, he came fourth and then two more people crossed after him. All right. So your answer is fourth place.

[01:00:25]All right. Good job. Excellent work.

[01:00:30]All right. Now, give me a thumbs up if you're good so far, we're almost at the end.

[01:00:43]Here it says, which number would be located at point P on the number line below?

[01:00:51]Which number would be located at point P on the number line below?

[01:01:01]Let's See?
