Numbers to 10

﻿Hello, my name's Miss Robinson. In this lesson, we're going to be looking at representing different numbers within 10. We're first going to recap counting how many of the different items there are looking at our big picture. Then we're going to look at some different ways to make five, look at some different ways to make six, and then it will be your turn to investigate different ways to make the number seven. Follow the steps and you will need 10 things that you can put into your tens frame. You will also need a tens frame. But you could draw this on a piece of paper, if you need to. Pause the video now to collect the resources that you need. When you're ready, press play. We're going to first start by recapping what we learned in the previous lesson about counting different sets of things. So, let me grab my pointer and we'll have a go at counting some things together. I'm going to start my counting some bears. One, two, three. There are three bears. Next, I'm going to count chairs. One, two, three, four. There are four chairs. Can you copy that sentence? There are four chairs. Fantastic. I'm going to count scarves next. There's one on the floor. One, two, three, and one more over here, four. There are four scarves. Can you copy my full sentence? There are four scarves. Fantastic. I've noticed something about those. They were four scarves and there were four chairs. They're different things, but there's the same amount of them, just like if on my bead string, I had four beads. And then I had four cubes. There are four of both items, but they're different items. So four cubes and four beads. They're the same, but I'm representing them in different ways. That's what we're going to be thinking about today. Let's have a look at some different ways that I can represent five. Here's some different tens frames and they all have five things in them. But they are all different things, and they're also all arranged in different ways. The first tens frame with apples has four apples at the top and one at the bottom. The one with the bananas has one at the top then bottom then top them bottom then top that's a bit like a pattern. The one with the cubes has all of the cubes over to the left hand side. That way is left. And the one with the pens has three at the top and two at the bottom. These are all different ways to show the number five, but they are all still five. Just like I was showing before with my beads, I can do the same with five. I can show you five beads, one, two, three, four, five. And I can also show you five cubes. One, two, three, four, five. There's five of each, but they are different representations because this one's cubes and this one's beads. So they're the same in that they are both five. But they're different because I've used different things, and maybe, like the tens frames, I could arrange them in different ways too. So I could have a little block of two and then a tower of three next to it. Still five altogether, but I've arranged them in a different way. We're going to do the same thing now with six. I'm going to show you my tens frames. I could start with something like this. I've got five at the top and one at the bottom. So almost all of my cubes at the top and one at the bottom. I could arrange it in a different way by moving all of those down there. And now I've got five of the bottom and one at the top. I could move this one to the other side. I could pop them into twos and have two, four, six. I could pop them like this. I could make three and three, or I could put all of them at one end. I'd have six altogether and a couple of empty spaces. Or at the other end like this. There are lots of different ways that I can make the number six in my tens frame. All the different ways that I represent it will be helping me to remember the number better. And remember the different parts that I can see, so I can see three at the top and three of the bottom, three and three makes six. I'm going to show you one more and we're going to play a quick game of memory. So you need to have your T your part home model and your things in front of you. This is a great game that you can play with a talk partner or a parent or carer at home. If you would like to practise making different parts of six in some different ways. So what I'm going to do is I'm going to arrange all of mine. First, I'm going to do it like this, and I'm going to show it to you for a few seconds, and then I'm going to hide it from you. Once I've hidden it, you need to have a go at making it on your tens frame in the exact same way that I've made mine. So, I'm going to hide it now, can you try and make that same arrangement that I made on your tens frame? Let's check and see. So you should have two over to the left hand side over here, and then a group of four altogether, two at the top and two at the bottom. If you got that right, give yourself a really big back pat on the back. That's fantastic. It's like a game of memory where you make the arrangements, so I might change it to be like this. I'll give you a few seconds to look, and then I hide it. And now it's your turn to try and make the same arrangement of six on your tens frame. Are you ready? So, hopefully you also had a full row at the bottom and one at the top. The more that you play this, the more you'll be able to visualise the different parts of six. And if you describe it to yourself in your head. So if you look at mine and say the bottom row was falling, there's one at the top on the right hand side. Then when it comes to your turn to make it on your path, on your tens frame, sorry, you will be able to imagine it clearer in your head because you've described it to yourself too. It's your turn to investigate different ways to arrange the number seven. That's your task for today. You need seven things and your tens frame. The things can be whatever you'd like, and you can arrange them in whatever way you'd like. You have to have a go at explaining the different way, the ways that you've arranged seven. And if you have somebody that you could play with, you could play at memory, just like we did together when we were arranging six. Pause the video now to investigate the number seven. When you're finished, press play. so, hopefully you've enjoyed investigating the number seven. And, if you were able to find a talk partner to play with, hopefully your partner did a really good job at playing memory with you. Let's compare the tens frames that are on the screen. What you need to do is find something that is either the same or is different about these tens frames. Can you tell me something that is different? I can tell you that they are all different colours. I can also tell you that the orange tens frame has four cubes, the purple tens frame has six cubes, the green tens frame has eight cubes, and the set, the blue tens frame has seven cubes. So they're all different amounts too, different quantities. Something that's the same about them is that they're all blocks. And they're all tens frames. And all of the numbers are less than 10 because in every single tens frame, there is at least one spare space. So I know all the numbers must be less than 10. They've also arranged them in lots of different ways, haven't they? So the first one has three at the top and one at the bottom. The second one has two at the top and four at the bottom. They've arranged them in different ways to represent the numbers, maybe even showing us some different parts. We don't just need to compare tens frames that have the same quantities. Sometimes we can compare tens frames that have different quantities, too. Thank you for joining me today for our work on representing different numbers within 10. You've done some fantastic learning. I hope you've enjoyed yourself. Why not share your work with us? If you'd like to, please ask your parent or carer to share your work on Twitter by you, by tagging @OakNational and using the #LearnwithOak. We'd love to see what you've been getting up to. Don't forget to go and complete the quiz. Thanks again for joining me. See you next time.
