﻿Hello, and welcome to our next lesson of weighing and comparing masses in mixed units. Now, by the end of this lesson, we're going to be able to compare different masses in different units, and be able to make good estimates to see which one's heavier or which one's lighter than each other. Let's start. Okay, so, we're going to go over what we're doing today. First, we're going to do kilogrammes and grammes, then we're going to be rehearsing the language of mixed units for mass, there will be way in a comparing with mixed units which will then get you guys ready for your independent task and then we can go over the answers. So let's get started. So first you're going to need a pencil, a rubber and an exercise book. So length or mass. What could we measure with these pieces of equipment name? Name items that you would use each piece of equipment to measure. So have a look at them all. Guys we've got one, two, three, four, five. Just tell them how do you know what they used for and what units will you use? So we have a tape measure. We might use that to measure the length of a book or a small item. We have some weighing scales here and some of them are used for small items. So I'd say this one could be used in the market to measure all the apples that you buy. This one could be used when you're making a cake at home with mom or dad. And this maybe is for higher, heavier items, okay? That you would maybe use for, if you're going to get a big bunch of potatoes, maybe. And we have a measuring tape which is normally used by tailors when they're trying to measure the size of your leg or your arms, okay? And the type of units we'll be using. Normally for length we go with centimetres or metres and for weight, as you know from our previous lesson, we will be working with grammes and kilogrammes. So kilogrammes and grammes. I'm going to show you a quick video how we can use a weighing scale to prove that one kilogramme is equal to 1,000 grammes. So let's watch. Okay, so these are the weights that we're going to be using and this is our scale. So we have one kg, 500, 200, 100 and five kg. And for it to be balanced the line has to be right there in the middle. So, let's start with one kilogramme. We're going to put it on one side and as you can see, it goes downwards. When it's lower that means it's heavier than the other side. Lower means heavier. 500 grammes. Now I'm going to use two, 500 grammes to make sure that that equals to one kilogramme. Let's prove it. Here comes a second one and it should be equal and balanced. That means that one kilogramme is equal to two, 500 grammes. Okay, good. Would be my petitions with proven things. Let's move on to 200 grammes. I know I need 200 grammes, 400 grammes, 600 grammes, 800 grammes, 1000 grammes, which is equal to one kilogramme. So let's try it out. We are going to prove it. Here we go, there's 200, there is 400, 600, 800 and 1,000 grammes. And this should balance out. We've proved it. It's equal to one kilogramme. Okay, so now that I've proved you guys we, as mathematicians, we need to make sure that we can prove things are correct. We are now going to this question. We have kilogrammes to grammes. So in that case, four kilogrammes is equal to, 400 grammes, 4,000 grammes, 400 kilogrammes or 4,000 kilogrammes. You can pause and try and work it out in your books. Okay, so the answer was? Drum roll. Four thousand grammes. Absolutely. Because we know that one kilogramme is equal to 1,000 grammes then 4,000 kilogrammes is equal to 4,000 grammes. Well done on guys? And we proved that before, didn't we? So we know that that is accurate. So now we're going to really get into our language and how we use it to explain mixed units in mass. So, here we have an example and the first weighing scales here we can see that there is two kilogrammes, which means that each one of these ones are equal to one kilogramme, okay? So therefore we have two kilogrammes here and we have three kilogrammes here. And these are the parcels that we are trying to measure. Now, the little green ones are all equal to 100 grammes too. So just bear that in mind. So let's start at the rehearsing. So this is the language I would like you to use. The mass of this parcel is greater than two kilogrammes, okay? And less than three kilogrammes I know this because the parcel is lower on the balance, as you can see here, lower on the balance than two kilogrammes but higher on the balance than three kilogrammes. We're going to have Susie helping us out. This is one kilogramme, two kilogrammes, 100 grammes and 200 grammes. The balance is about level when there is two kilogrammes and 200 grammes in the other bucket. So this parcel weighs about two kilogrammes and 200 grammes. And that is the language you're going to be using. Let's try the next one. Let's have a look then. We have these weighing scales in either side we're going to use this to help us with this vocabulary. So the mass of this parcel is greater than, that's right, four kilogrammes, and it's less than, write that, five kilogrammes. I know this because the parcel is, now have a look, is it low or higher? It is lower on the balance than the four kilogrammes but it is higher or lower on the balance compared to the five kilogrammes? It is higher on the balance than five kilogrammes. Good, really good guys. It's really important that we use this language higher or lower, okay? Then we're going to move on to this one. Let's have a look, okay. So that is one, two, three, four kilogrammes and 100, 200, 300, 400, 400 grammes. The balance is about level when there is, what did we say all together? Four kilogrammes and 400 grammes and the other buckets. So this parcel weighs about four kilogrammes and 400 grammes. Really working at the vocabulary. Have a moment to read for one more time before we go into your task. Right, now it's your turn. So, having a look at these images what is the mass of the parcel? I would like you to pause the video and work it out for me now. And remember use that vocabulary; higher, lower. Off you go. Okay, let's see how we got on. So what is the mass of the parcel? Let's have a look. We have, right here, well, I know that it is, is it higher or lower compared to the three kilogrammes? It is lower therefore it is heavier than three kilogrammes. Okay, good. I know that because the parcel is higher, okay? Then that means that it is lighter than the four kilogrammes. So we know is in between three kilogrammes and four kilogrammes. Okay, so let's find out, let's see, look at the next package to help us. Let's have a look. It is one kilogramme, two kilogrammes, three kilogrammes. Okay, and let's count the 100 grammes. 100, 200, 300, 400, 500, 600 grammes. Because it is level we can say that the parcel is three kilogrammes. Okay, which one is it going to be? And 600, ah, you're right, grammes. So let's see if we are correct. Well done. Three kilogrammes and 600 grammes. Fantastic work guys, well done. Okay, so now we're going to be weighing and comparing with mixed units. So we're going to be using what we learned before. So remember our five steps. So the first one is, what is the scale? Well, in this case we are actually going to be using mixed units. So it's going to be grammes and kilogrammes, okay? What two intervals is it in between? Well, when we look at our indicator we know that it's in between one kilogramme and two kilogrammes, okay? And what's the value of the intervals? Now we have to go back to what we were thinking. So let's have a look at one kilogramme to two kilogrammes. That means the total in between these two is one kilogramme. So that means we need to think. Let's count the intervals. Are you ready? One, two, three, four, five, six, seven, eight, nine, 10. So, 10 intervals that make one kilogramme. 10 intervals that make 1,000 grammes. I think I'm going to use my 10 times tables. I'm going to go 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. Well, if I went and did that with 100 and we can go 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000. There it is. That means that each interval is equal to 100 grammes. Okay? Now, in that case I am looking for this indicator there. So I know that I'm going to go from one kilogramme when I count top 100 grammes, 200 grammes, 300 grammes, okay? So now I'm going to put them together as a mixed unit. So altogether, this kitten right here, weighs one kilogramme, okay? And 300 grammes. Remember it's about, is an estimate. Right, are we ready for the next one? Here we go. First step, what is the scale? In this case we're going to be using grammes and kilogrammes. Well done. What two intervals is in between? Well, let's have a look at a scale. We have one kilogramme and two kilogrammes. Well done, guys. What are the values of intervals? Ah, this looks very similar to the last weighing scale but let me just double check. Let's have a look in between and we have one two, three, four, five, six, seven, eight, nine, 10. We know that if there are 10 intervals in 1,000 grammes, which is equal to one kilogramme, therefore each interval is going to equal 100 grammes. Now this time we need to count up to our interval. So is one kilogramme and this count up. Are we ready? 100, 200, 300, 400, 500, 600, 700, 800, 900. Okay, there we go. Our final measurement is going to be one kilogramme and 900 grammes. Well done guys? That was really good work from you. Are we ready? It's time for you guys to do this independently. Here we go. What is the mass of this kitten? Now, it's a completely different kitten guys. So it wasn't the same one as before. We can tell by the measurements on our scale. So, pause the video now and work it out. Don't forget those five steps. What is the scale? Where is the indicator in between? What is the value of each interval? Okay. Counting up in grammes or kilogrammes and then your final estimate. Off you go. So what is the message of this kitten? Here we go. So, first thing, what is the scale? Well, we know that the scale is grammes and kilogrammes. Excellent. Well, what is the indicator in between? Well we can see that it's in between one kilogramme and two kilogrammes. Good. Third step, was what is the value of our intervals? Well, there are 10 intervals in between one kilogramme and two kilogrammes. So, therefore, we know that each interval is equal to 100 grammes. Good guys, well done. We now need to count up in grammes or kilogrammes. So let's count and it goes, 100, 200, 300, 400, 500, 600, 700 grammes. That means our final mass of this kitten, sorry, is a one kilogramme and 700 grammes. Is this one, right? This one? No, be careful. What's your units? It is definitely not. It's not 700 kilogrammes. That would be crazy, crazy heavy. Our kitten has not eaten that much, okay? This is the value and it is one kilogramme and 700 grammes. Well done. If you still make mistakes, maybe go back to the slides and go through the steps with me again. It's time for our independent task. Here we go. Right guys. So, independence task time. I am really needing your help. I need you to find out the mass of our four animals. They all look pretty similar I think they're all related. What I'd like you to do is, is use the same techniques for us that we're going to be finding these out in mixed units. Okay, so it will be in kilogrammes and in grammes. You're now going to pause the video and you're going to go to your worksheets and try them out for me and then we're going to come back here for the answers. Good luck. Okay, time for the answers. So let's start with question number one. We have our lovely singing parrot. First step, what is the scale? The scale is grammes and kilogrammes. Excellent. Number two, what two intervals is in between? Yes, it is one kilogramme and two kilogrammes. Really good. What are the value of each intervals? Well, as before we know that there are ten intervals in between one kilogramme and two kilogrammes therefore each interval is going to equal 100 grammes. Well done guys. We're now going to count up in grammes to where our indicator is. Here we go. 100, 200, 300, 400 grammes. And we going to add them together to have a final mass of one kilogrammes and 400 grammes. Well done guys? If it doesn't like mine, fix it now. Let's move on to the next one. Right, here we go. We've got our tiger who is a handsome looking tiger, isn't it? Number one, what is the scale? Again we are on grammes and kilogrammes, okay? What two intervals is it in between? In this case it is four kilogrammes and five kilogrammes. Okay. What are the value of each interval? Well, let's have a look. This is slightly different to other ones so we're going to count. One, two, three, four, five, six, seven, eight, nine, 10. Oh, well, it's very, it's exactly the same. It may look different. It's a different look and scale but the intervals are exactly the same. There are ten intervals that are worth 1,000 grammes. Therefore, each interval is going to equal 100 grammes. We're now going to count up in grammes. Here we go. 100, 200 grammes. There we go and we're going to add it all together and we're going to get well, that's four plus 200, so that's 204 kilogrammes, right? No, absolutely not. You never, ever, add kilogrammes and grammes together. They're different units, completely. Therefore, finally it is four kilogrammes and 200 grammes. Well done guys. If it doesn't look like mine, fix it now. Let's move on to the next one. All right, we have our little teddy here. Really nice, oh, I love the colour. It suits in really well. Number one, what is the scale? Well again, grammes and kilogrammes. And what two intervals is it in between? Well, it's between two kilogrammes and three kilogrammes. Okay, what are the values of the intervals? Well, let's have a look. One, two, three, four, five, six, seven, eight, nine, 10 again. Oh, in that case we know this is easy by now. Each interval is therefore equal to 100 grammes. And then we're going to count up in grammes to where our indicator is, 100, 200, 300 grammes. And we're going to add the values together. Oh, never add the values together. Kilogrammes and grammes never add together. So the mass of this wonderful teddy bear is, two kilogrammes and 300 grammes. Well done guys. If it doesn't look like mine fix it now please. Let's go to the next one. Oh, this poor dog looks a little bit sad. Right, first, what is the scale? We know that the scale is kilogrammes and grammes. So what are the values of intervals? Again, we have 10 intervals of the value of 1,000 grammes therefore each interval is equal to 100 grammes. We're then going to count up in grammes. And it is one, two, three, four, 500 grammes. And then we're going to do the values together as two kilogrammes and 300 grammes. Okay, there we go. That is our answer. Well done guys that was great work from you. If it doesn't look like mine fix it now. That brings us to the end of today's lesson. A really big thank you to all the fantastic learning you have done today. You've been incredible. I've got two final things I'd like you to know. First, if you're able to, please take a picture of your work and ask parent or carer to share it with your teacher so they can see the fantastic things you have learned today. Second, if you'd like, ask the parents or carer to send a picture of your work to, @OakNational on Twitter so then I can see your lovely work too and it'd be great to see whether we're learning together. That's it for today. Thank you so much. Take care and enjoy the rest of your learning, for today. Bye.

﻿Hello, and welcome to our next lesson of weighing and comparing masses in mixed units. Now, by the end of this lesson, we're going to be able to compare different masses in different units and be able to make good estimates to see which one's heavier or which one's lighter than each other. Let's start. Okay. So, we're going to go over what we're doing today. First, we're going to do kilogrammes and grammes. Then we're going to be rehearsing the language of mixed units for mass. There will be weighing and comparing with mixed units, which will then get you guys ready for your independent task, and then we can go over the answers. So let's get started. So first you're going to need a pencil, a rubber, and an exercise book. So length or mass? What could we measure with these pieces of equipment? Name items that you would use each piece of equipment to measure. So have a look at them all. There, we've got one, two, three, four, five. Just tell me, how do you know what they used for and what units will you use? So we have a tape measure. We might use that to measure the length of a book or a small item. We have some weighing scales here and some of them are used for small items. So I'd say, this one could be used in the market to measure all the apples that you buy. This one could be used when you're making a cake at home with mom or dad. And this maybe is for higher, heavier items. Okay? That you would maybe use if you're going to get a big bunch of potatoes maybe. And we have a measuring tape, which is normally used by tailors when they're trying to measure the size of your leg or your arms. Okay? And the type of units we'll be using, normally for length, we go with centimetres or metres, and for weight, as you know from our previous lesson, we will be working with grammes and kilogrammes. So kilogrammes and grammes. I'm going to show you a quick video, how we can use a weighing scale to prove that one kilogramme is equal to 1000 grammes. So let's watch. Okay, so these are the weights that we're going to be using and this is our scale. So we have one kg, 500, 200, 105 kg, and for it to be balanced, the line has to be right there in the middle. So, let's start with one kilogramme. We're going to put it on one side and as you can see, it goes downwards. When it's lower, that means it's heavier than the other side. Lower means heavier. 500 grammes. Now I'm going to use two 500 grammes to make sure that that equals to one kilogramme. Let's prove it. Here comes a second one and it should be equal and balanced. That means that one kilogramme is equal to two, 500 grammes. Okay. Good. We're being mathematicians, we're proving things. Let's move on to 200 grammes. I know I need 200 grammes, 400 grammes, 600 grammes, 800 grammes, 1000 grammes, which is equal to one kilogramme. So let's try it out. We're going to prove it. Here we go. There's 200. There is 400, 600, 800 and 1000 grammes and this should balance out. We've proved it. It's equal to one kilogramme. Okay. So now that I've proved you guys, as mathematicians we need to make sure that we can prove things are correct. We are now going to do this question. We have kilogrammes to grammes. So, in that case, four kilogrammes is equal to 400 grammes, 4,000 grammes, 400 kilogrammes or 4,000 kilogrammes? You can pause and try and work it out in your books. Okay, so the answer was... Drum roll. 4,000 grammes. Absolutely. Because we know that one kilogramme is equal to 1000 grammes, then 4,000 kilogrammes is equal to 4,000 grammes. Well done guys. And we proved it before, didn't we? So we know that that is accurate. So now we're going to really get into our language and how we use it to explain mixed units in mass. So, here we have an example and the first weighing scales here, we can see that there is two kilogrammes, which means that each one of these ones are equal to one kilogramme. Okay? So therefore we have two kilogrammes here, and we have three kilogrammes here. And these are the parcels that we are trying to measure. Now, the little green ones are all equal to 100 grammes too. So just bear that in mind. So, let's start the rehearsing. So this is the language I would like you to use. The mass of this parcel, is greater than two kilogrammes. Okay? And less than three kilogrammes. I know this because the parcel is lower on the balance, as you can see here, low on the balance than two kilogrammes, but higher on the balance than three kilogrammes. We're going to have Suzie helping us out. "This is one kilogramme, "two kilogrammes, 100 grammes and 200 grammes. "The balance is about level "when there is two kilogrammes "and 200 grammes in the other bucket." So this parcel weighs about two kilogrammes and 200 grammes. And that is the language you're going to be using. Let's try the next one. Let's have a look. Then we have these weighing scales on either side. We're going to use this to help us with this vocabulary. So the mass of this parcel is greater than, that's right, four kilogrammes and it's less than, right there, five kilogrammes. I know this because the parcel is... Now have a look. Is it lower or higher? It is lower on the balance than the four kilogrammes, but it is higher or lower on the balance compared to the five kilogrammes? It is, higher on the balance than five kilogrammes. Good. Really good guys. It's really important that we use this language, higher or lower. Okay? Then, we're going to move on to this one. Let's have a look. Okay. So that is one, two, three, four kilogrammes, and 100, 200, 300, 400, 400 grammes. The balance is about level when there is, what do we say all together? Four kilogrammes or 400 grammes in the other bucket. So this parcel weights about, four kilogrammes and 400 grammes. Really working at the vocabulary. Have a moment to read through it one more time before we go into your task. Right. Now, it's your turn. So, having a look at these images, what is the mass of the parcel? I would like you to pause the video and work it out for me now. And remember, use the vocabulary, higher, lower. Off you go. Okay. Let's see how we got on. So, what is the mass of the parcel? Let's have a look. We have right here. Well, I know that it is... Is it higher or lower compared to the three kilogrammes? It is lower, therefore, it is heavier than three kilogrammes. Okay. Good. I know that because the parcel is higher. Okay? Then that means that it is, lighter than the four kilogrammes. So we know is in between three kilogrammes and four kilogrammes. Okay? So let's find out. Let's see. Look at the next package to help us. Let's have a look. It is one kilogramme, two kilogrammes, three kilogrammes. Okay? And let's count the 100 grammes. 100, 200, 300, 400, 500, 600 grammes. Because it is level, we can say that the parcel is three kilogrammes, okay? Which one is it going to be? And 600... Ah, you're right. Grammes. So let's see if we are correct. Well done. Three kilogrammes and 600 grammes. Fantastic work guys. Well done. Okay. So now we're going to be weighing and comparing with mixed units. So we're going to be using what we learned before. So remember our five steps. So the first one is, what is a scale? Well, in this case, we are actually going to be using mixed units. So it's going to be grammes and kilogrammes. Okay? What two intervals is it in between? Well, when we look at our indicator, we know that it's in between one kilogramme and two kilogrammes. Okay? And what are the value of the intervals. Now, we have to go back to what we were thinking. So let's have a look at one kilogramme to two kilogrammes. That means the total, in between these two is one kilogramme. So that means we need to think let's count the intervals. Are you ready? One, two, three, four, five, six, seven, eight, nine, 10. So, 10 intervals that make one kilogramme. 10 intervals that make 1000 grammes. I think I'm going to use my 10 times tables. I'm going to go 10, 20, 30, 40, 50, 60, 70, 80, 90, a hundred. What if I went and did that with a hundred and we can go, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000. There it is. That means that each interval is equal to 100 grammes. Okay? Now, in that case, I am looking for this indicator there. So I know that I'm going to go from one kilogramme. I'm going to count up 100 grammes, 200 grammes, 300 grammes. Okay? So now I'm going to put them together as a mixed unit. So all together, this kitten right here weighs one kilogramme, okay? And 300 grammes. And remember it's about, this is an estimate. Right. Are we ready for the next one? Here we go. First step. What is the scale? In this case, we're going to be using, grammes and kilogrammes. Well done. What two intervals is it in between? Well, let's have a look at our scale. We have one kilogramme and two kilogrammes. Well done guys. What are the values of the intervals? Ah, this looks very similar to the last weighing scale but let me just double-check. Let's have a look. In between, and we have one, two, three, four, five, six, seven, eight, nine, 10. We know, that if there are 10 intervals in 1000 grammes, which is equal to one kilogramme, therefore each interval is going to equal, 100 grammes. Now, this time we need to count up to our interval. So there's one kilogramme and let's count up. Are we ready? 100, 200, 300, 400, 500, 600, 700, 800, 900. Okay. There we go. Our final measurement is going to be, one kilogramme and 900 grammes. Well done guys? That was really good work from you. Are we ready? It's time for you guys to do this independently. Here we go. What is the mass of this kitten? Now it's a completely different kitten guys. So it's not the same one as before. We can tell by the measurements on our scale. So, pause the video now and work it out. Don't forget those five steps. What is the scale? Where is the indicator in between? What is the value of each interval? Okay? Counting up in grammes or kilogrammes, and then you're final estimate. Off you go. So what is the mass of this kitten? Here we go. So, first thing, what is the scale? Well, we know that the scale is grammes and kilogrammes. Excellent. Well, what is the indicator in between? Well we can see that it's in between one kilogramme and two kilogrammes. Good. Third step was what is the value of our intervals? Well, there are 10 intervals in between one kilogramme and two kilogrammes, so therefore we know that each interval is equal to 100 grammes. Good guys. Well done. We now need to count up in grammes or kilogrammes. So let's count. And it goes. 100, 200, 300, 400, 500, 600, 700 grammes. That means, our final mass of this kitten, sorry, is one kilogramme and 700 grammes. It's this one, right? This one? No. Be careful. Watch your units. It is definitely not. It is not 700 kilogrammes. That would be crazy, crazy heavy. Our kitten has not eaten that much. Okay? This is the value and it is one kilogramme and 700 grammes. Well done. If you're still making mistakes, maybe go back to the slides and go through the steps with me again. It's time, for our independent task. Here we go. All right guys. So, independent task time. I am really needing your help. I need you to find out the mass of our four animals. They all look pretty similar. I think they're all related. What I'd like you to do is use the same techniques for us that we're going to be finding this out in mixed units. Okay? So it will be in kilogrammes and in grammes. You're now going to pause the video and you're going to go to your worksheets and try them out for me and then we're going to come back here for the answers. Good luck. Okay. Time for the answers. So let's start with question number one. We have our lovely singing parrot. First step, what is the scale? The scale is grammes and kilogrammes. Excellent. Number two. What two intervals is it in between? Yes, it is one kilogramme and two kilogrammes. Really good. What are the value of each intervals? Well, as before we know that there are 10 intervals in between one kilogramme and two kilogrammes, therefore, each interval is going to equal, 100 grammes. Well done guys. We're now going to count up in grammes to where our indicator is. Here we go. 100, 200, 300, 400 grammes and we're going to add them together to have a final mass of one kilogramme and 400 grammes. Well done guys. If it doesn't look like mine, fix it now. Let's move on to the next one. Right. Here we go. We've got our tiger, who is a handsome looking tiger, isn't he? Number one. What is the scale? Again, we are on grammes and kilogrammes, okay? What two intervals is it in between? In this case, it is four kilogrammes and five kilogrammes. Okay. What are the value of each interval? Well, let's have a look. This is slightly different to the other one, so we're going to count. One, two, three, four, five, six, seven, eight, nine, 10. Oh, well, it's exactly the same. It may look different. It's a different looking scale, but the intervals are exactly the same. There are 10 intervals that are worth 1000 grammes, therefore, each interval is going to equal, 100 grammes. We're now going to count up in grammes. Here we go. 100, 200 grammes there we go and we're going to add it all together and we're going to get, well, that's four plus 200 so that's 204 kilogrammes, right? No, absolutely not. You never ever add kilogrammes and grammes together. They're different units completely. Therefore, finally it is four kilogrammes and 200 grammes. Well done guys. If it doesn't look like mine, fix it now. Let's move on to the next one. All right. We have our little teddy here. Really nice. Oh, I love the colour. It suits him really well. Number one, what is the scale? Well, again, grammes and kilogrammes. What two intervals is it in between? Well, it's between two kilogrammes and three kilogrammes. Okay. What are the values of the intervals? Well, let's have a look. One, two, three, four, five, six, seven, eight, nine, 10 again. Oh, well in that case we know this is easy by now. Each interval is therefore equal to 100 grammes, and then we're going to count up in grammes to where our indicator is. 100, 200, 300 grammes. And we're going to add the values together. Oh, never add the values together. Kilogrammes and grammes never add together. So, the mass of this wonderful teddy bear is, two kilogrammes and 300 grammes. Well done guys. If it doesn't look like mine, fix it now please. Let's go to the next one. Oh, this poor dog looks a little bit sad. Alright. First, what is the scale? We know that the scale is kilogrammes and grammes. So, what are the values of the intervals? Again, we have 10 intervals of the value of 1000 grammes, therefore, each interval is equal to 100 grammes. We're then going to count up in grammes and it is one, two, three, four, 500 grammes. And then we're going to do the values together as two kilogrammes and 300 grammes. Okay? There we go. That is our answer. Well done guys. That was great work from you. If it doesn't look like mine, fix it now. That brings us to the end of today's lesson. A really quick thank you to all the fantastic learning you have done today. You've been incredible. I've got two final things I'd like you to know. First, if you're able to, please take a picture of your work and ask your parent or carer to share it with your teacher so they can see the fantastic things you have learned today. Second, if you'd like, ask your parent or carer to send a picture of your work to @OakNational on Twitter, so then I can see your lovely work too and it'd be great to see how we're learning together. That's it for today. Thank you so much. Take care and enjoy the rest of your learning for today. Bye.
