Applying "Make 10" to differences.

Hello, everybody, it's Miss Sidhu here.

And we are going to produce some amazing math with you today.

In this lesson, you will be using the "Make 10" strategy, to find the differences between numbers.

Let's get started.

In today's lesson.

We will be using the "Make 10" strategy using the vocabulary are star words, less, greater and difference, an independent task, and finally, end of lesson quiz, to see everything that we have learned.

You will need a pencil and a paper, and a number line to help you find the difference.

In the video, there might be times that you need to pause to have a go at some of the activities yourself.

But first let's warm up our brains.

I'm super excited.

I want you to match the shapes to the correct name.

I want you to match the shapes to their word form.

I want you to pause the video, and have a go at matching them up.

Are you ready? Steady, go.

How did you get on? Have a look and see if you were correct.

We've got the red circle, we've got the green square, we've got the blue triangle and we've got the purple pentagon.

Hope you had super fun when matching the shapes to the name.

Here we have a number line.

What is the difference between nine and 13? Does it matter which number we start on, on the number line? It doesn't matter because we can go forward or backwards.

Let's say if we start at the number eight, Ooh, is there number eight? Ah, the number nine.

Thank you for helping me.

I think we should jump forwards and start at the number nine.

Let's try and see how many jumps it would take to get to 13.

Can you count with me? One, two, three, four, four jumps from nine to 13, which means there's a difference of four.

Is there another way of jumping? How about we jump from nine to 10, to make 10? And then we know that there's three jumps from 10 to 13, so we can use the "Make 10" strategy.

Let's go from nine to 10.

That's one jump, and then we can go from 10 to 13.

And we know that's three jumps because 10 and three make 13.

One plus three makes four, which means there's a difference of four, between nine and 13.

What's the difference between 14 and seven? Let's use the "Make 10" strategy to find it out.

We need to jump from 14 to 10 and or do you know that's four jumps at 10 and four make 14, we can do one big jump to make it easier.

We just need to jump to seven, which is three more jumps because I know seven and three make 10, it'll be from 10 to seven is three jumps, and we've got one, two, three.

We know that four plus three is equal to seven, there's a difference of seven between 14 and seven.

Good job.

It's your turn to try.

What is the difference between 16 and seven? I want you to use the " Make 10" strategy to find out.

You can start at seven or you can start at 16, and then jump to 10.

I want you to pause the video and have a go.

How did you do? From 16 to 10 is six, and then from 10 to seven is three, six plus three is nine.

The difference between 16 and seven is nine.

How did you do? I think you're ready for today's independent task.

For your task today, you need to find the difference between seven and 13.

The difference between seven and 13 is, I jumped something and then something.

You need to use the "Make 10" strategy to do the two numbers, to add them together, to find the difference.

I want you to pause the video to complete your task and resume once you're finished.

Here's the answers.

The difference between seven and six, seven and 13 is six.

I jumped three and then three.

The difference is six and I jumped three and then three.

I would like you to share your work with Oak National.

Please ask your parent or carer to share your work on Twitter, Instagram, or Facebook tagging @OakNational and hashtag #LearnwithOak.

I want you to complete the quiz to see everything that you have learned.
