Lesson video

Describing and completing number patterns.

Hello everybody, I'm Miss Sidhu and we are going to be doing some wonderful maths with you today.

Now in this lesson, you will be describing and completing patterns.

Maybe you might know some patterns that you can see.

Now let's get started.

Welcome to today's lesson.

In today's lesson, we are going to be describing number patterns, completing number patterns, an independent task, and end of lesson quiz to see everything that we have learned.

Today, you will need a pencil and a paper and a number square to 50.

There are times in the video that you may need to pause and have a go at some of the activities yourself.

Now let's get started.

Before we begin the lesson, let's warm up our brains.

Let's recap time.

What time do you think these clock faces show? Can you match them to the correct times? I want you to pause the video and have a go at matching the correct time and the clock.

Pause and freeze, macaroni cheese.

How did you do, did you get the same as me? We've got the first clock shows half past seven and the second clock shows half past nine.

Good job everybody.

Now have a look at these numbers.

What numbers are there? Let's go through them.

So we've got 34, 35, 36, 37, 38.

What can you tell me about this pattern? I want you to pause the video, have a think and then tell the person next to you.

What is happening in this pattern? How did you get on? What have you noticed about these numbers? Can you shout it after three, one, two, three? Oh, lots of you are saying that the numbers are getting bigger.

So I think these numbers are increasing.

Increasing means getting bigger.

Do you agree? Are these numbers increasing? Yeah, good work, I agree.

How much are they increasing by? When we look at patterns like this, there are two things we need to find out before we can continue the pattern or find any missing numbers.

First, we need to know if they are increasing like this, which means getting bigger, or if they are decreasing, which means getting smaller.

Then we have to find out how many they are increasing or decreasing by.

For this pattern each number increases by one.

So from 34 to 35, it increases by one.

Now let's have a look at another pattern.

So here we've got the pattern, it's the same pattern.

We know that the pattern is increasing and that it is increasing by one each time, but we need to find out what the next number is.

So what do you think the next number will be? You may want to pause the video to have a think.

So what's the next number in the pattern? Now we know that the pattern is increasing and that it's increasing by one each time.

So what will be our next number? Say it nice and loud.

What will be our next number? Excellent work, I could hear so many of you shouting at the screens.

The next number is 39.

Great work everybody, well done.

Now let's have a look at a different pattern.

Let's try another one.

What is happening in this pattern? Remember the two things that you need to find out.

Is it increasing or decreasing, and how many by? Okay, how can we find this information? I want you to pause the video and see what you can find out about this pattern.

So pause the video, have a think, and then tell the person next to you.

What is happening in this pattern? How did you do? Did you find out if it's increasing or decreasing? Shout it out after three, one, two, three.

Wow, I agree, this pattern is decreasing.

The numbers are getting smaller.

Now we need to find out how many it is decreasing by.

We can use a number line to help us find out.

If we start on 30 on the number line, can you point to the number 30 on the number line? There we've got 30, and as our pattern starts with the number 30, then we can jump until we reach the number 28 as the next number in the pattern is 28.

Now let's have a go at counting the jumps.

So one, two.

So from 30 to 28, one, two, we've made two jumps, which means that the pattern is decreasing by two each time.

The pattern is decreasing by two.

Let's say it again.

The pattern is decreasing by two.

Using this information, what would be the next number? I want you to pause the video and work it out.

So what's the next number? How did you get on? Did you manage to find the next number? Can you shout it out? You did great.

The answer is 22.

Great work everyone, your making me feel very, very happy today.

I want you to see if you can find out what would come next in this pattern.

Remember the two things you need to find out first, is it increasing or decreasing, and how many by? You may want to pause the video to have a go.

So what would come next in this pattern and how do you know? Take a look at mine and check it against yours.

Did you get the correct numbers? We've got it's increasing by one.

So we've got 37, 38, 39, and then we have 40, 41.

How did you do? Great counting everybody.

Now take a look at these number lines.

Some of these are patterns, but others are not.

Which ones are patterns? Try and explain why you think that.

So which ones of these number lines are patterns? or why not? I want you to pause the video, have a think which ones are patterns or why not, and then tell the person next to you.

Let's have a look together and see which ones are patterns and why we think that.

The first one, this one is a pattern because the jumps are all equal.

They are increasing by five each time.

So if you look at the bottom parts of the arrow, they are increasing by five each time.

The next one, this one isn't a pattern because they are increasing by different amounts each time, which means it cannot be a pattern as it is not equal.

This one is a pattern because it is increasing equally each time it jumps.

And the last one, do you think it's a pattern or not a pattern? That's right, this one isn't a pattern.

So it's not a pattern because it isn't equal each time it increases.

I think you are ready for your independent task today.

For your independent task, I want you to complete the pattern by finding out if it increases or decreases, and by how many each time.

Here you have another pattern to find out.

And another pattern.

Can you complete the pattern of the caterpillar by finding out if it increases or decreases, and by how many each time? You may want to use your number square to help you.

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

Here are the answers.

This pattern increases by one each time.

So you've got 16, 17, 18, 19, 20, 21, 22.

This pattern decreases by one each time.

So 38, 37, 36, 35, 34, 33, 32.

This pattern increases by two each time.

So counting in twos, eight, 10, 12, 14, 16, 18, 20, 22.

How did you do? I hope you got them all correct.

Now, if you would like 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 #LearnwithOak.

You did an amazing job today in counting all of our different patterns and describing the patterns too.

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

And now that's good-bye for me because it's already the end of the lesson.

Bye.
