Lesson video

Hi, my name is Miss Robson.

In this lesson, we're going to practise sharing numbers beyond 20.

First I'm going to tell you a few stories about the characters from the Hey Diddle Diddle rhyme, and how they had to share some things out, then it'll be your turn to see if things are equal or there not equal when we share them.

And finally, you'll have some numbers to investigate sharing out between the characters.

For this lesson, you will need 30 things.

So I have my counters because they're little and I've got lots of them.

So find 30 of something.

And you will also need a sharing sheets.

Pause the video now to collect these resources if you need and when you're ready, press play.

So we're going to start with a story to help us put the sharing of numbers beyond 20 into a context so into a story for us to help understand.

On the screen you can see all five of the characters from the Hey Diddle Diddle story We have the cow, the cat's with his fiddle, the dog, the dish and the spoon.

One day the cow went off for a big walk and he came back with 25 sweets that he had found in the forest.

He decided to share them out.

Have a look and see what happened.

Here my characters I've written their names at the top in case you don't know who they are because my drawings are a little bit interesting.

I've got the cow, the dog, the cat, the dish and the spoon and I need the 25 sweets that the cow found in the forest so two, four, six, eight, 10, 12, 14, 16, 18, 20, 21, 22, 23, 24 25 sweets all together, here are the 25 sweets that the cow found in the forest.

So I have my sweets all here at the bottom.

And I have my one, two, three, four, five characters and their five groups, they have a group.

So I have my 25 sweets and I have the five characters at the top, which means that I have five groups to share into.

I'm going to use my One for you, one for you method, I'd love you to join in with me.

So basically, every time I give one to the cow, one to the dog one to the cat, I say one for you.

That way, I remember where I'm up to because I'm going across the page like this but also I'm remembering to hand one to each character as I go.

So, one for you, One for you, one for you, one for you, One for you, one for you, one for you, one for you, one for you, one for you, one for you, one for you, One for you.

whoopsies make sure that he's in his group, One for you, one for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, one for you, one for you, one for you and lucky last one for you.

So, because I ended on my last character, I would think they would be the same but I am going to count and check just in case.

So one, two, three, four, five, five for the Cow one, two, three, four, five five for the dog one, two, three, four, five, five sweets to the cat one, two, three, four, five, five sweets for the dish and one, two, three, four, five, five sweets for the spoon, they are equal.

Let me draw my equal sign, equal.

They all have the same quantity of sweets.

So that is a fair share, fantastic job at finding 25 sweets cow because that was a number that we could share into these five groups.

So he could share those sweets equally between his friends.

That was fantastic, That meant that each person, each of the characters got five sweets and they would have all been very happy because that is a fair share that is equal.

So the cow could share his sweets out and give each of his friends five each.

So that's equal, that's fair.

They all got the same amount, that's fantastic.

But what happens next was the spoon decided he didn't want any sweets.

He was all full and he decided that he had had enough and he didn't need any of the sweets.

So the cow had to try sharing again, but this time just between himself and his three friends.

So instead of sharing into five groups, now he's sharing into four.

Let's see what happens.

I still have my 25 sweets, but this spoon has decided that he doesn't want any.

So I'm going to cross him out.

Spoon and I'm going to put a big squiggle in his column.

So remember, he does not want any sweets.

So this time I'm going to try sharing out these sweets, but just between the four characters that want some sweets, none for the spoon, One for you, one for you, can you join in, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you and one for the cow.

One, two, three four, five, six, seven for the cow One, two, three four, five, six for the dog One, two, three four, five, six, sweets for the dog, for the cat sorry, One, two, three four, five, six, sweets for the dish.

So six, six, six and seven.

Hmm, it's not equal.

Its not equal Not equal.

What if I gave this one to the dog, then this six, six, six but still one of them has seven.

So still not equal or if I gave this fair one, Ooh can't I give this fair one to anyone because then someone's always going to have seven and someone else is always going to have six.

So 25 cannot be shared between four equally.

It would be fine if one of them was okay with having an extra one, but it's still not going to be equal because they are not having the same amount of sweets its not fair.

So that one didn't work did it.

Not all of the characters could have the same amount of sweets, it doesn't share equally into four groups.

So we know that 25 cannot be shared into four groups.

Today you're going to be investigating the same story, but with different quantities of sweets.

Here is your sharing sheets, If you don't have one or if you'd like to, you can just draw yours like I drew mine.

You also have on the sides and different quantities, so 30 sweets, 20 sweets, 16 sweets, 28 sweets, 12, sweets and 26 sweets.

What you're going to do is what we've just been doing, telling a story if you like and then sharing out that many between the four characters.

When you've shared them you need to count and check to see if they are equal or if they are not equal.

So if they're not equal, we might pop them in one pile.

And if they are equal, you can put them in another the pile so it can be shared cannot be shared.

That way we'll know which quantities of sweets can be shared equally amongst the four friends.

Let me show you me sharing one of the sweets to decide whether it's equal or not equal.

I'm going to start by trying to share 12 sweets So I need to start by just getting 12 and I'll do that in twos Two, four, six, eight, 10, 12.

So I don't need the rest of my counters just yet.

I have 12 sweets to share out.

And remember the spoon still doesn't want any.

So I'm only sharing these 12 sweets between four groups between the four characters none are going to the spoon.

So I'm going to use my one for you one for you method.

Can you join him with saying it as I say it, one for you, One for you, One for you, One for you, one for you, One for you, one for you, One for you, one for you, One for you, one for you, and one for you.

Look three, three, three, three 12 can be shared equally between four groups.

So I'm going to write that here 12, So remember 12 can be shared equally between four groups, I might keep them, I might keep sorry, writing them next to equal or not equal each time so that I can remember which ones I could share equally, and which ones I could not share equally.

So 12, I could share equally because each character got three, they are the same, I could even line them up like this to check that my four groups are all the same.

because they're all the same size, I can see that three, three, three, three I've got four groups of three there.

Now it's time for you to pause the video and complete your task.

Remember, you need to share into the four groups and afterwards check to make sure if they're equal or not.

Pause the video now to complete your task.

And when you're ready, press play.

What did you find out? which of those numbers could be shared and which ones couldn't be shared? Can you points now to the two that couldn't be shared? The two that I couldn't share were 30 sweets and 26 sweets, give me a thumbs up if that's the same as the ones that you couldn't share or a thumbs down if you found two different ones.

Excellent, When I shared 30 sweets between the four friends, I could not get the groups to be the same size.

I tried a few different times just to make sure and each time using my One for you, one for you, one for you method, I couldn't make the group's equal.

So 30 could not be shared between four and the same for 26.

It just wasn't right.

If you've enjoyed today's activity, you could share in your environment, you could set up a teddy bears picnic, you can decide how many groups you have by deciding how many teddy bears there are.

And you can share things out to them.

Whether that's using your counters, or your cubes, or whatever use today and your imagination to say I'm sharing out this many apples.

Or you could actually share out things that you have around you like toys or books.

When you've shared you can check afterwards to see if it is equal or if it's not equal, if it's fair, or if it's not fair.

I hope you've enjoyed this lesson on sharing.

I know that I've really enjoyed sharing out the sweets to the different characters from the story, and I hope that you've enjoyed it too.
