# Lesson video

In progress...

Hello, I'm Miss Martin, last lesson, we were looking at equal groups and we were looking at how many groups we had and how many objects were in each group.

I set you a little challenge at the end of last lesson, with six objects and 12 objects.

And I asked you to see if you could find different ways of arranging them into equal groups.

Let's have a look at how you got on.

So we started with our six objects, didn't we? We need six of the same objects, but they didn't have to be identical because we knew that they could be different sizes and different colours from our previous lessons.

How did you arrange them into equal groups? Now, there were a couple of ways you might've done this.

So let's look at the first way you might've done it.

You might have arranged your cubes or your bricks, or your pieces of pasta into two equal groups.

There're two equal groups of cubes.

And how many cubes are in each group? There are three cubes in each group, fantastic.

And know if we count our groups, we have got one group of three, two groups of three, so there are two groups of three, fantastic.

You might have arranged your six subjects in this way, or you might've done it in a different way.

Let's look at the next way.

You might have arranged your six objects like this.

So this time, instead of there being two equal groups, there are how many equal groups are there? Fantastic, there are three equal groups of cubes and how many keeps them in each group? That's right, there are two cubes in each group.

And so then let's count our groups, one group of two, two groups of two, three groups of two.

Fantastic, there are three groups of two.

Once you did it with six objects, I asked you to do it with 12 and you might have drawn these or you might've used some of the same objects again.

It didn't matter which one you preferred to so long as you had the same type of objects.

Let's have a look at what I used.

For the 12 objects, I used my potato stamper, and then I put them into groups.

Now this was a little bit tricky because I had to make sure that all my groups were equal.

So this is how I arrange my stars into equal groups last time.

How many equal groups of stars are there? There are four equal groups of stars.

Fantastic.

How many stars are in each group? That's right, there are three stars in each group.

And then let's count how a groups together.

There are one group of three, two groups of three, three groups of three, four groups of three.

There are four groups of three.

You might've circled your picture in different ways, or you might have arranged your objects in different ways.

Did you do it in any of these ways? Let's look at the first picture, the top one.

How many equal groups can you see? I can see, one group of two, two groups of two, three groups of two, four groups of two, five groups of two, six groups of two.

I can see six groups of two.

Let's look at the bottom one.

How many equal groups can you see? One group of six, two groups of six.

There are two groups of six.

It was hard to this time, wasn't it? Sometime to make sure that we circled equally.

Did anybody circle five stars to start with? If you did, you might've realise that you couldn't make equal groups.

It's a little bit tricky one we have to draw around the groups.

You might have arranged your objects or circled your pictures in a different way.

Did any of you do it this way? Let's look at the top picture.

How many equal groups can we see? One group of three, two groups of three, three groups of three, four groups of three.

I can see four groups of three.

Let's look at the bottom one then.

How many groups can we see here? One group of four, two groups of four, three groups of four.

I can see three groups of four.

Well done for all your work on the practise activity last lesson.

In today's lesson, we're going to carry on looking at our equal groups.

And we're going to look carefully , which number represents how many objects in a group and which number represents how many groups we have.

Look at the picture on the screen.

What can you see? That's right, there's a little rowing boat with some children inside it.

Now this picture is a little bit different to the pictures we looked at last lesson, because I don't need to draw around the circle this time or make them onto your plate to group them.

The children are already grouped because they are sat all in one boat that makes it easier for us to count.

One boat is one group.

So, how many groups can you see? That's right, there is one group because there's one boat.

How many children can you see in the boat? That's right, there were three in the group.

Can you say that with me? There were three in the group.

Fantastic.

So if I count my groups, there is one group of three.

Fantastic.

Oh, hang on a minute, I think these children are going to be joined by more children in the boats.

Let's take a look.

Now there are two boats with children and I can still see that the groups are equal.

Can you help fill in the missing words in my sentences.

Press pause on the video and have a little go.

Did you work it out? Could you see what the missing words are? How many equal groups are there? There are.

That's right, two equal groups of children because we'd already decided definitely that one boat is one group, and now we can see that there are two boats.

So there are two equal groups of children.

And how many children are in each group? That's right, there are three in each group.

Fantastic.

And then if we count our groups, we've got one group of three, two groups of three.

So there are two groups of three.

Fantastic.

Some more boats have arrived now.

Can you help me see how many equal groups there are now? I've got some sentences again, but they're still missing the numbers in them.

Can you help fill in the blanks for me, please? Press pause on the video.

Are you ready to help me? Excellent, thank you.

How many equal groups are there? Brilliant, there are four equal groups of children.

We can see that because we can see the four boats.

And we know that one boat is one group.

And remember we didn't need to circle them because the children are sat inside the boat.

So we can see that one boat is one group.

And how many in each group? That's right, there are three in each group.

Fantastic, you can see three children are sat in each of the groups.

Can you count the groups with me then? One group of three, two groups of three, three groups of three, four groups of three.

Fantastic, so there are four groups of three.

Brilliant, thank you for helping me.

More boats and more children have joined us now.

And we've got the challenge question.

Do you think you can help me? Fantastic.

So the challenge question says, "Which sentence correctly describes the picture?" The first sentence says, "There are six equal groups." And the second sentence says, "There are three equal groups." So which of those sentences do we think correctly describes the picture? There are six equal groups, or there are three equal groups? Hmm it's a bit tricky this one, you press pause on the video and have a little think and you can come back and help me.

Have you worked out, do you think you can help me? Thank you.

So do you remember when we said that we would call a boat a group? That's really going to help us now.

So let's count the groups that we can see.

So I can see one group, two groups, three groups, four groups, five groups, six groups.

How many groups can we see? Six equal groups, amazing.

Let's say that sentence together.

There are six equal groups.

Aw, well done.

It's not there are three equal groups, is that there are six equal groups, fantastic.

We've gone away from the river now and we've moved to the fairground.

Can you see all the bumper cars? Have you ever been on a bumper car? The great fun, aren't they? So again, I don't need to circle the children, it's just like the boats because they're all in one bumper car.

So one bumper car is one group.

Now we've got to true or false question, and true or false questions can be a little bit tricky.

You up for the challenge? I thought you would be.

So the sentence says, "There are two groups of six." And we need to decide, is that true or is it false? In our last example with the boats, we only needed to count how many equal groups we had.

But this time we need to think about how many children are in each group two.

The little bit trickier, isn't it? Press pause on the video and have a think, is that sentence true or false? There are two groups of six, true or false press pause now.

Have you worked it out? Amazing, can you help me? Super, let's count our groups to see if we can work it out.

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.

So we have six groups of two, but the sentences says, there are two groups of six.

Is that true then or is it false? That's right, it must be false, mustn't it? Because we didn't find two groups of six, we found six groups of two.

We have six equal groups and there are two children in each group.

Brilliant, well done.

So we know that the correct sentence must be, there are six groups of two.

Can you see that sentence with me? There are six groups of two.

Well done.

Now we have two images to choose from, to match to the sentence, set A show some dogs in groups and set B show some stars in groups.

And the sentence says, "There are three groups of five." To set A or set B show that there are three groups of five.

What do you think? So we can work this one out together by thinking about the number of equal groups and the numbers inside each group.

So the sentence says.

"There are three groups of five." Which set shows three groups of five, which one has three groups of five? Pause the video and think.

What did you decide? Excellent, set B shows that there are three groups of five, doesn't it? We've got five stars in each group and there are three groups, well done.

Where at set A, how many groups were there in set A? That's right, there were five groups in set A, and how many dogs are in each group? Three so there were, five groups of three in set A.

So that didn't match our sentence, did it? Well done.

For today's best practise activity.

I would like you to try and finish the sentences by looking at the nests.

You've had lots and lots of practise at this during this lesson.

So I know you're going to do really well with it.

As an extra challenge, if you're up for a little bit of an art activity, I would like you to do a little bit of drawing.

I have started to draw some equal groups of ice creams, hmm.

But I haven't finished it, and I wondered, can you help finish my drawing for me please? So I want to have four groups of three.

Do you think you can finish my drawing? If you have done like four groups of three, I wonder how might you three groups of four look different? Could you try to draw me some more ice cream cones to show me three groups of four? Well done for all your hard work in today's lesson, you did an amazing job counting out equal groups and counting how many objects were in each group.

You've done a really great job, thank you.

Bring your ice cream cone pictures and your sentences to the next lesson and I'm Miss Evans we'll go through them with you then.

Bye.
