Multiples madness

Ok, welcome back mathematicians and welcome back Barbara.

Hi Michelle it's nice to see you.

It's battle number seven million, five hundred and twenty two about to commence.

And this time I'm hoping to beat you.

You see Multiples madness.

Ok, so this is how we play.

I'll allow you to start.

You're welcome, we only get five counters each, so this time you can be represented for red and I'll be represented for green for go.

Dreadful, I'm going to stop you.

Red for stop.

And so spin the spinner.

Oops, there we go.

Ok, one.

So you get one, fives, or five ones as your go.

Ok, so what is 5 X 1 or 1 X 5? Ah, five.

Ok.

So I record it for you.

So you got one and that's 1 X 5 which is five and then you have to cover five on the game board using one of your counters.

Ok.

Uhm, and you'll notice that five's in different places, so you could use any of those.

Ok, how do I win? What do I do?

Three in a row.

The first person to get three in a row.

So I need to be clever about where I put it.

Yeah, ok.

Ok, it's my turn.

Would you mind passing me the spinner?

Sure, there you go.

Thank you.

I got a six.

So six, fives is thirty.

It's a number fact I know, but I could check by going five, ten, fifteen, twenty, twenty five thirty.

So you would write that I rolled a six, and then 6 X 5 or six, fives.

Yep, what would you like me to write?

Six, fives, I like that better.

I feel like it means more.

Yeah, 'cause it's like they're in groups of five and there are six of them.

You have six, fives and I covered thirty in total.

And I'm going to choose this thirty because I think it's the only one there.

Oh no, there's one there as well.

So now I have to be clever.

If I get a forty five I would, Oh no, I could still go for this one.

Yeah.

Yeah.

Ok, your go.

I'll spin this way.

One, again.

Which is?

Which is five.

Ok.

But I don't have any that are lined up with this one, so I guess I'll just put it here.

Ok, my turn.

Thank you.

And three and so three, fives is fifteen.

That's a number fact, I know, but if I didn't know, I could use that skip counting again.

So five, ten, fifteen.

And I am going to go here.

Because that's too far away, I think.

OK, if I get a four it could be game over already.

Alright.

It could be the fastest victory in history.

That would.

Unless you get a four and you block me.

Yeah, Ok, so I want a four or I actually just want something that goes next to my like fives.

Ok, lets see.

Zero.

So, you rolled a zero and you have zero fives which means I have got nothing, so zero.

But that's ok. 'Cause there is a spot for zero.

There is a spot for zero, but it doesn't actually really fit in very well.

Oh, no, this one does, Ok.

You know what's good about this game?

They often, you know in a lot of games when you roll a really low number or you spin a really low number, you can't go or it doesn't, where as this game it doesn't really matter.

That's true.

I didn't get a four but I got a three.

So three, fives is fifteen and I know that.

So my only other option for fifteen is up here for now.

Would you like me to write it three, fives or another way?

Do 3 X 5 this time using symbols.

But it's the same.

Ok, my turn, alright.

So now what do I want?

I want forty five.

So I want, Oh, yeah you do too.

And you've got two choices.

Look forty five and forty five.

I know I could double win.

Oh, and if you got thirty five, you'd be so close.

Oh, Ok.

Right.

Eight, Ok so.

I've got eight, fives.

Yes.

So I know four, fives is twenty.

Yes.

So then double that, is forty.

So I agree with you.

I'll put that there.

So that's actually a pretty good spot.

So eight, eight, fives is forty.

Ok, that's very close.

May I please have the, thank you, spinning pencil, the spinning pencil of doom?

Five, Oh, I like this five, fives are twenty five.

I just actually really like that 'cause it sounds nice five, fives are twenty five.

I like how it looks when you imagine it.

In the red square.

I love square numbers like sixteen.

Um, and now I need to decide whether I go here, or here.

But here's more useful for me so I'm gonna go there.

Ok.

It is more useful for you but in that one you kind of blocked me a little bit, so.

I know.

It depends whether you're playing offense or defense.

Well I'm probably not playing either.

Oh, hold on it was five wasn't it?

Five, fives.

Nice revising.

Ok, your go.

You're paying attention.

Oh we're going to run out of counters, so then we have to make some choices, right?

Yep, then you have to lose one.

Yes.

Yes.

Ok, now nine, fives.

Don't put that tone on because you won.

I want to explain my thinking.

So I know that five, tens is fifty.

Yes.

Um, so that five, tens is also fifty.

So then if I take one of those fives away, I'll have forty five.

And you have actually got multiple choices of victory.

You could have victory in the top left corner.

Can I even move that one over there and get double.

Oh look.

I got a connect 4.

Ok, I'll settle for just three in a row.

Congratulations.

That's a great game.

It's a very heartfelt congratulations.

Yeah, it is a great game and we actually have a version of this that you can play using twos.

So you can work on understanding multiples of two and also tens.

So there are some other number facts that you can use this game to get more confident with.

So over to you mathematicians.

You might even come up with your own version of the game.
