101 and you're out!

Good afternoon everybody. Hi Barbara.

Hi Michelle, How you going?

I'm good. I'm ready to win.

Yeah, I was gonna say that alright, well to win we're playing a new game today called 101 and bust. OK, so the goal is to get 100 or as close to 100 as possible without going over.

OK.

We need this dice and we need a table to help us record our thinking. So we need to drawour table as a 7 by 4 table. And then I'll usually just halve it. That's good to make four columns. And then I halve the half because when you halve 1/2 of 1/2 is 1/4. OK. And then we need 7 rows. How do we do that? Just try our best? Yeah, well, I usually, because if we got one section already done, you've now need 6 equal pieces and I can relate 6 to halves and thirds. So if I halve it like you just did and then I can just sort of get my eye in and third each section. Yeah. OK, alright so up here is, we need the labels tens, then ones, then number and total.

And we can roll one dice. Or we can roll 2 and we each have one that we use but we will just share this one today and we roll the dice and we have to decide with the 4 if we want the 4 to be worth 4 tens which we would then rename as 40 or 4 ones which we would call four. So for me I think I'm going to call it 4 tens. So I would record it like this, I've got 4 tens, the numbers's 40 and so far my total is 40 because 0 + 40 is 40.

I think I'm going to do the same as you.

OK.

OK. Um, I think I might do this one also as 4 tens. Ok, I'm gonna do it as 4 ones. And so my 4 ones and my total now is 4 tens and 4 ones which we would rename is 44. It's my roll.

I'm sorry.

That's alright. And a four. That one I will definitely do as 4 ones. I'm going to do 4 ones also. So 44 and 4 more for me is 48. 80 and 4 more for me is 84. OK, so I think now I need to do most of these as ones because I'm quite close to one hundred.

Yeah, because if you had 3 tens more than 80. I would bust. That would be 11 tens.

You'd be over.

I'd be over.

But I'm going use tens, so I'm going to say 3 tenswhich is 30, oops, that's right, and 4 tens and 3 tens of 7 tens and 8 more is called 78. Ok, 84 and 3 more is 87.

Ok, we're pretty close now.

Whoo, it's close. Ones. Definitely ones.

Um, 5. And 87, three more for 90 and then two more so I've 92.

I have 83 because I needed two more to get to 80 and then three more makes 83. Oh, ok. So, I don't think either of us can get exactly 100 now.

No. Because you would need 8 and the dice doesn't go that far and I need 17.

I actually think I will win.

Well I could win though, because if it rolls 1 ten I get 83 and you get 93. I can't win, we can tie.

Come on tie. Oh, a 5. Well, I'm definitely five ones, which is 5 and now I've got to 97. So, you're the the closest. Congratulations, you're the winner.

Thank you very much.

But let's play again, best out of three? Ok, deal. Over to you mathematicians?
