Hey, fellow mathers! Welcome to the podcast where Math is Figure-Out-Able. I'm Pam.

Kim  00:06

And I'm Kim

Pam  00:07

And this episode is a MathStratChat episode because we chat about our math strategies. Every Wednesday evening, I'll throw out a math problem on social media, and people from around the world chat about the strategies they use, and comment on each other's thinking. 

Kim  00:20

Okay, this Wednesday, our math problem was 8 times 75. How would you solve this problem? Pause. Solve it however you'd like. The problem is 8 times 75. 

Pam  00:30

Alright, ya'll, we're supposed to actually pause and solve that, and then come back. Here we are. KK, Kim, let's see. I'm going to go first this time, if you don't mind. 

Kim  00:38

Yeah.

Pam  00:39

I would like to use an Over strategy. 

Kim  00:41

Okie doke.

Pam  00:42

So, I'm going to think about ten 75s.

Kim  00:45

Mmhm. 

Pam  00:46

And that's 750. Okay, but I only need eight 75s, so two 75s is 150. So, 750 minus that 150 is 600. Final answer. 

Kim  00:59

Final answer. I am going to go... You used one of my favorite strategies, so I'm going to use one you mentioned last week that is my son's favorite strategies, and that is Double Halve.

Pam  01:10

Mmm, mmhm. 

Kim  01:11

And so, I know that 8 times 75 is equivalent to 4 times 150. And I won't stop there, but I'll Double/Halve again, and I'll say that that is equivalent to 2 times 300. And I'm going to stop there because that is 600.

Pam  01:29

Awesome. I have a question.

Kim  01:30

Yeah? 

Pam  01:31

Could you think about 8 times 75 using quarters? I don't do that well yet.

Kim  01:40

It's so funny because when you said ten 75s, I wondered if you were thinking about, like if you pictured the 3 quarters. I think it depends on how many 75s we're talking about.

Pam  01:52

Okay. 

Kim  01:53

So, I don't know that I specifically thought about 3 quarters here. 

Pam  02:00

I don't think you did, but could you?

Kim  02:03

Sure, and then I'd put... 

Pam  02:06

I want to learn. I want to learn. I want to learn how you would think about quarters.

Kim  02:11

Well, I think that I would do... It's kind of like 8 times 25 times 3. 

Pam  02:20

Okay.

Kim  02:21

So, then the 25 times 3 is the 3 quarters.

Pam  02:25

Mmhm.

Kim  02:26

So, then I would think, for each of the... Oh, how to explain. So, then I would have 24 quarters because I have 8 times 25 times 3. 

Pam  02:39

Oh, okay, yeah. 

Kim  02:40

So, then I know I have 24 quarters. But then I'd do some work to figure out the 24 quarters. 

Pam  02:47

Okay, so I also got 8 times 3 times 25.

Kim  02:51

Mmhm. 

Pam  02:52

And then I thought about 8 quarters to get 200. 

Kim  02:58

Mmhm.

Pam  02:58

And then scaled that times 3. 

Kim  03:00

Mmhm, that's great.

Pam  03:01

Okay, so I'm getting better. 

Kim  03:02

Yeah, yeah.

Pam  03:02

I have to force myself to do that. That took some... 

Kim  03:05

Well, good for you! That's fantastic! Yeah! 

Pam  03:07

I want my brain to go there next time. 

Kim  03:09

Yeah, okay. Super. Alright, well, we can't wait, every week, to see what you guys do in MathStratChat. Join us and let us know how you're thinking about the problems, and please comment on each other's strategies. People we love that.

Pam  03:21

Yeah, we do love it. We'll post the problems on Wednesday around 7:00 pm Central. When you answer, tag me, and use the hashtag MathStratChat, and then join us here to hear how we're thinking about the problem. We love having you as part of the Math is Figure-Out-Able movement.
