﻿Hello there everyone. How are you doing? It's Mrs. Khaira. And of course it's Elvis my fantastical mathematical assistance. Now in this lesson we're going to be consolidating our learning of grouping and sharing. That means we're going to do some revising of this unit and make sure that we know what we're talking about when we talk about grouping and sharing. I hope you're ready to begin. We've got a lot to fit in. Let's get cracking. Now in this lesson you're going to need the following items. You will require some counting objects. So I've got my counters but you can use whatever you have to hand. And you'll also need the activity sheets available in today's resources. Please ask a parent or carer to help you cut out the cards if you're using scissors. Now, if you haven't got these things ready, please press the pause button, go and collect what you need and then resume the video. So here is our big picture for this unit. Can you remember which nursery rhyme this picture comes from? That's right, it's "Baa Baa Black Sheep." I wonder if you can sing the first verse of the nursery rhyme along with me. Should we have a go together? ♪ Baa baa black sheep ♪ ♪ Have you any wool ♪ ♪ Yes sir ♪ ♪ Yes sir ♪ ♪ Three bags full ♪ ♪ One for the master ♪ ♪ One for the dame ♪ ♪ One for the little boy who lives down the lane ♪ Great singing everybody. Now I've represented some of Baa Baa Black sheep's balls of wool using some of my counters here. Now I wonder if you can help me to count up the number of counters I have. I have organised my counters into groups of five. We've got one, two, three, and four groups of five. Can you help me to count in fives to find out how many counters we've got all together? Let's start here. Five, 10, 15, 20. Great counting everybody. There are 20 counters all together on the table. Now, I want to try and arrange my 20 counters in to different groups. I wonder if you can help me to do this. Let's start by arranging the counters into groups of two. Let's do this now. So we've got one group of two, two groups of two, three groups of two, four groups of two, five groups of two, six groups of two, seven groups of two, eight groups of two, nine groups of two and 10 groups of two. I have made 10 groups of two. 10 groups of two counters is equal to 20 counters all together. Let's see if we can do it in another way now. How about we make groups of four counters. Let's do this now. So we've got one, two, three, and four counters. Let's put them together. One, two, three, and four counters. Let's put them together. One, two, three, and four counters. I'll put them together like that. One, two, three, and four counters. There's another group. And one, two, three, and four counters. Now, can you tell me how many groups of four we have made all together? Perhaps we can count them up to check. We've got one group of four, two groups of four, three groups of four, four groups of four and five groups of four. Altogether we have made five groups of four. Five groups of four counters is equal to the number 20. Now for our new learning today we're going to continue to explore the relationship between sharing and grouping. In the picture on the screen, you can see two of old Farmer MacDonald's fields. And I have represented his fields here using two coloured pieces of card. Now, old MacDonald would like to share 12 of his cows across the two fields. He wants to make sure that there is an equal number of cows in each field. I have represented his 12 cows and using counters. Let's count to make sure that I've definitely got 12. One, two, three, four, five, six, seven, eight, nine, 10, 11, and 12. Now, if we want to share them equally between the two fields, we're going to have to place the same number in both of them. We're going to move one counter into one field and the next counter into the next field. And we'll keep doing that until we finish all of the counters. Let's begin now. So let's put one counter here and one counter there. One counter into this field and one counter into that field. One counter goes into this field, one counter goes there. One counter into this field and one counter into that field. One counter goes here, one counter goes there. One counter goes here and one counter goes there. Now, can you tell me how many cows they'll be in each field? You'll have to count the counters very carefully to find out. Let's check if you're right. In the first field there will be one, two, three, four, five, and six cows. And in the second field there will be one, two, three, four, five, and six cows. We have been able to share the 12 cows equally between the two fields. 12 shared between two is equal to six counters in each. Now we can also explain that in terms of groups. We have managed to make two groups. Each group contains six counters. Two groups of six counters makes 12 all together. So two groups of six are equal to 12. So let's have a look at our talk task for today. For this activity you're going to need the following things; you'll need the activity one and activity two cards. You'll also need a selection of counting objects so I've got my counters. And you'll need the help of your talk partner. So I've got Elvis here to give me a helping hand. So we're going to start by looking at the first card. Now, we need to be able to count up the number of animals we have on this card. So can you help me to do that please? We've got one, two, three, four, five and six. There are six sheep on this card. I am going to represent those six sheep using my counters. So I'm going to put the counter onto each one. One, two, three, four, five and six, There are my six sheep represented by my six counters. Now, Elvis is going to help me with the next part. He has got the next card that we need to look at. It matches the same animal that we have in our first card. Elvis is going to help me explain the groupings that have been done in the second card. And we're going to use our counters again to help us do this. So we're going to move our counters from this card to the other, looking at the groups that we create in the process. So, I can see that the first group here has got one and two sheep in it. I can see here the second group has got one and two sheep in it. And I can see that the third group here has also got one and two sheep in it. So, Elvis has just told me that we can explain this picture in two ways. We can say that our six sheep have been shared equally between three groups. Six shared between three groups is equal to two. Because there are two sheep in each group. Elvis is also very clever. He has just spotted that we can also say something else. We could also say that three groups of two counters each are equal to six. So, now it's your turn. With your talk partner you're going to need to get a set of the cards that we've used in this activity from the resources today. Have a go at grouping the animals and then explaining to your partner how you've grouped and how you've shared the counters out. Once you and your partner have had a go you can resume the video and we'll carry on with our learning. Now in my classroom today, there were 25 children present. And here I have represented the 25 children using 25 counters. Now today was a very exciting day because the 25 children were all going to go to old MacDonald's farm. But there was a bit of a problem. Only five children could fit in each car. So I needed to work out how many cars we needed to take. Can you help me to put the children into groups of five? Each group of five will represent one car that the children can travel to the farm in. Let's do this together now. I'm going to represent each car using a different piece of coloured card. So let's count our first group of five. One, two, three, four, and five. Here is our first group of five children. They will be taking one car. Let's see if we can make another group. One, two, three, four, and five. Here is our second group of children. They will be travelling in another car. Can we make any more, I wonder? Let's see. One, two, three, four, and five. Here is our third group of children they'll be travelling in another car. Let's see if we can make any more groups of five. One, two, three, four, and five. Here is our fourth group of children. They will be travelling in the fourth car. Perhaps we have enough children to put into one more car. Let's check to see. One, two, three, four, and five. Here is our fifth car. This is the fifth group of children travelling to the farm. So all together, how many groups of five did we make? Let's check to see. One, two, three, four, and five. That means that we've been able to make five groups of five counters. Five groups of five counters is equal to 25 children all together. Now we can also talk about how we've shared the counters. 25 counters shared between five groups is equal to five counters in each group. So now it's your turn to have a go. In a moment, you're going to pause the video and then using 20 counters this time, I'd like you to have a go at grouping the children into groups of five. How many groups can you make? Then can you use your maths language to explain how you have shared and grouped the counters using my model sentence stems to help you. Once you've had a go at the activity, you can resume the video and we'll finish off with our learning for today. Today everyone. Now here are 15 of the animals that the children saw today when they visited old MacDonald's farm. Now old MacDonald has asked the children to help him with a problem. He wants to put the 15 animals into his fields. But, he wants the children to decide whether we should group the animals first or whether we should try and share the animals. Well, Elvis has suggested that perhaps we should try and share the animals first. Well, that's a good idea. I'm going to represent the three field using three different coloured pieces of card. One, two, and three. Now, I want to see if I can share my 15 animals equally between the three fields. One for each field. Two animals on each field, Three animals on each field. Four animals on each field. And five animals on each field. So, we have shared our 15 animals out equally between the three fields. How many animals are there on each field? That's right. There are five animals on each field. That means that 15 shared equally between three groups is equal to five animals on each field. Now we can also talk about these animals in terms of our groups. Three groups of five animals each is equal to 15 animals all together. Three groups of five is equal to 15. Fantastic learning today everyone and well done for all the work that you've done across this unit. Now, if you'd like to share your work with Oak National, then please ask your parent or carer to share your work on Twitter, tagging @OakNational and #LearnwithOak.
