reSolve double decker bus 2

Hello there mathematicians, welcome back to another delightful day of reasoning and problem solving and creative thinking.

So my friend at Kristin Tripit sent a follow-up question for us for today and before we get into it let's remind ourselves of some things that we realized yesterday. So we noticed yesterday that there's lots of different strategies that you could use, to you, to solve the same problem and some strategies are more efficient than others.

Yes. Well remembered, that efficiency is about the number of steps that you have to take, not about how fast something is. Well not just about that. Mm-hmm.

And the other thing that was really helpful for us, yesterday, that you're gonna have to use today, is this idea that as the mathematicians we get to be in charge of the numbers. Yep, so we can see 8 and 7 and rethink of that as 5 and 10. We can use these ideas of equivalents. Or we can see 8 and 7 and rethink of that as 7 and 3 and 5. Mm-hmm, because we know 8 can be broken up into chunks of 3 and 5.

Okay, here's Kristen's challenge for you today mathematicians. Which strategy would you use if you were solving these problems? What if, on the bus, there are 7 on the top and 6 on the bottom? What strategy would you use? What if there are 5 on the top and 8 on the bottom? What if there are 12 on the top and 9 on the bottom? And what about 9 on the top and 8 on the bottom? And what about 7 on the top and 9 on the bottom?

So mathematicians, I'd like you to choose 3 of your favorite scenarios or questions there, and have a go of thinking about what are 2 at least, 2 different strategies that you could use to solve your 3 favorite problems?

Okay, over to you mathematicians!
