﻿- Hi, welcome to your math lesson with me, Mrs. Harris. We're going to do some matching today, we'll be doing matching of unequal sets. Now, don't worry if you don't know what that is, we'll find out together. This is what we're going to do today its called our lesson agenda. Now, the first thing we will do , is we'll do some learning together. We'll find out more about what matching unequal sets actually means and how to do it. And then we'll do some practise together. That will be our guided practise, because I'll be there to guide you. And we'll finish the lesson with you doing some practise all by yourself. Using all the skills you've learned. This is all you're going to need today. And it is available for you to print, with your parent or carers permission. But don't worry if you can't, I'll pop it on the screen for us as well later. This is the part of the lesson where we're going to learn together. And look, I've brought some friends to help me. They're a little bit hungry, and they'd love to share this pile of sweets that's in front of them. I'm going to help them with the sharing. First thing I'm going to do actually is sought the sweets out. I'm going to put all my blue sweets there, all my red sweets there into a group together and all my black ones there together. That'll make it easier for me to share them out. Let me start with the red sweets. I think they'd all quite like one of them. So one for you, one for you and one for you. Look, they all have one of the red sweets. And there's none, left on the table. I have an equal number of red sweets to animals. They can all have one each with none left over. I bet they're happy with that. So maybe they can gobble them up. Oh, what do you fancy, the blue sweets next. So I've got my pile of blue sweets. I've got my animals and I'm going to do just the same again and give them one each. So one for you, Oh, there's no more blue sweets? Oh, no. I'm sorry. You can't have a blue sweet. And you can't have a blue sweet. I have too few blue sweets. I have more animals than I have blue sweets. I've got an unequal group here haven't I. Its not like with my red ones, where they could have one each. Only, this one's got one of the blue sweets. That's just not fair. We prop that over there. That leaves me with the black sweets left. I wonder if this will be an equal group or an unequal group. Remember, equal's where they can have one each, with none left over. An unequal means maybe they can't have one each. Or I have more sweets than I do animals. Less sweets than I do animals. So let's see. So one for you, one for you, and one for you. I thought I had an equal group for a minute because I've given them one each. But look, I've got one left over. I've got more sweets than I do animals. I have an unequal group. Oh dear, there's only one thing for it, one for me. Thanks for helping me share the chocolate out amongst my friends and working out if I had an equal group or an unequal group. Maybe I had unequal groups inside where I had too many or too few. Take a look at this picture is a little bit healthier than chocolates. Nice juicy apples. Do we have an equal group? Could I give one to each child? Or do I have an unequal group? Have I got too many apples? Or too few apples for them to have? That's right, I have just enough apples. I can give each child one apple, and have none left over. I can give the girl in a red dress an apple. I can give the boy in a blue t-shirt an apple. I can give the girl in the yellow dress an Apple. And I have an apple for the boy in the green t-shirt. And no more. I can say this as a sentence. I can say, I have enough apples. could you say that with me? I have enough apples. Now, can you say it by yourself? Good job. I have enough, sorry. I have enough apples. I have an equal amount of apples to the children. But look, now, something's changed. What's changed? Do I have an equal amount of children to apples? No. I have more apples than children? Don't I? I have too many apples. Can you say that with me? I have too many apples. I do not have an equal group here. In fact, I have unequal groups unequal groups. Oh no, something's changed again. What's happened here? I have an unequal group again, don't I? My groups are unequal. They're not the same. I have too few apples. I do not have enough apples. Look, I can't give an apple to the girl in the yellow dress. Or to the boy in the green t-shirt. I have too few apples. I do not have enough apples. Oh dear, unequal groups, I don't really like them. Oh, well. Here's a little job for you now. I need you to remember the sentences that we had. I need you to remember the words enough, too many and too few. Or that I don't have enough, we start with setting up a picnic. And you've got this printed out too. I want you to use the sentences we've been practising to describe what's happened. As I've set up my picnic, it is your independent practise. The part of the lesson that I'd like you to do by yourself. I would like you to look at the picture from the teddy bears picnic, and use the stem sentences that we've been working on where I have enough, I have too many, or I do not have enough. To describe the things you can see in the picture. So pause the video now and come back to me when you've done it. And we'll look at some of my ideas together. Hi, how did you get on with that? Did you enjoy looking at the picture of the teddy bears picnic and seeing how I'd set it up? And how I could describe it. Well, here are my sentences that I came up with. Maybe yours were similar. I have more bears than spaces at the table. I do don't I? I have more bears, than I've got room for at the table. I have too many bears. Lets put that one away I have enough forks. I know I have enough forks because look every Teddy Bear has a fork. I have enough forks. I have fewer knives than forks. I do have fewer knives and forks don't I? This one teddy bear that does not have a knife. I have fewer knives then forks. I have too few knives. I don't have enough do I? Thank you for looking at my picnic with me and to using them sentences to describe the things that I had equal amounts of too many and, too few of not enough. We've reached the end of our lesson, but maybe you would like to set your own picnic up. And as you do so you can describe what you have just enough of too many of and not enough of too few of. Just before I say goodbye, I thought you might like to know how you can share your work with me. What you need to do is ask a parent or carer to share it, on Instagram, Facebook or Twitter tagging @oaknational. I'd love to see what you've been up to. Bye

In this lesson, we will explore the concept of unequal sets to identify whether or not there are the same amount or not.
