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

Kim  0:07  
And I'm Kim Montague.

Pam  0:08  
And this is a...

Kim  0:09  
That's you this time!

Pam  0:13  
This is a MathStratChat episode where I'm going to talk very clearly. Where we chat about our math strategies. Every Wednesday evening, I 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  0:26  
Okay,

Kim  0:27  
so this Wednesday, our problem was 15 times 96. How would you like to solve this problem? Pause the podcast, solve it, and then come on back to hear how we are going to talk about it. 15 times 96.

Kim  0:41  
Do you want to go first? 

Pam  0:43  
So, interesting. I'm kind of playing with a couple different things. I'm not sure I love this problem. Or maybe I do love this problem, but I don't.

Kim  0:53  
I love this problem. 

Pam  0:54  
You love this problem. I got to tell you. I tried like three things that I didn't finish before I

Pam  1:01  
settled. 

Kim  1:01  
I love that. Yeah, that is. You're playing. (unclear).

Pam  1:06  
I hope

Pam  1:06  
this recording is working. You're like, jittery on my screen.

Kim  1:09  
Ugh. Maybe it's me. 

Pam  1:10  
No, no. It's my computer. It's like, it's not you. It's like the app. The app is like, bouncing up and down. I'm going to stop looking at it. I'm actually going to think about 15 times

Pam  1:21  
100.

Kim  1:22  
Ah, you stole my thinking! Okay.

Kim  1:23  
Haha! So, a hundred

Pam  1:25  
15s is 1500. But I don't want one hundred 15s, I only want ninety-six 15s, so I don't need four 15s. And four 15s... I got to tell you, Kim. Much of my adulthood, I did not own four 15s. I do now. Now, that pings for me. Isn't that interesting? I knew you would go, "Really, you didn't own four 15s?" I did not. So, four 15s is 60. I do now own that. And so 1500 minus 60, play a little I Have, You Need, is going to be 1440. 

Kim  1:54  
Nice. 

Pam  1:54  
Alright, what were you thinking?

Kim  1:54  
Well, that's what I was thinking. But I will... Since it's times 15, I'll use Five is Half of Ten. So, 10 times 96 is 960.

Pam  2:04  
Mmhm.

Kim  2:05  
Half of that, 5 times 96, would be 480.

Pam  2:08  
How do you know half of 960?

Kim  2:10  
Yeah, I did half of 900, which is 450. Hnd half of 60.

Pam  2:16  
So, do you know I now know half of 96? So...

Kim  2:19  
Oh.

Pam  2:20  
Yeah, that's a relationship that I was like, "That's for 48 right? Yep." Like, I had to check it.

Pam  2:26  
I now own that one. 

Kim  2:27  
I'm so

Kim  2:27  
mad I didn't think about that. You knowwhy I should know that?

Pam  2:31  
Mmm? 

Kim  2:31  
Because my husband works...

Pam  2:34  
It's not a contest, but mmhm.

Kim  2:36  
Well, no. I just I'm happy that you said that you know that because it made me think how would I know that?

Pam  2:42  
Ah. 

Kim  2:42  
So...

Pam  2:44  
How would we know that? 

Kim  2:45  
Because my husband works 48 hours, and then he's home 96 hours. 

Pam  2:51  
Oh, look at that. 

Kim  2:52  
So, like it's just something that hadn't occurred to me, and so now it will occur to me, so thank you for saying that.

Pam  2:57  
So, that's where I then was like, then I can't... 960 and 480.

Kim  3:02  
Yeah.

Pam  3:02  
I just didn't want to go there. I was like, meh. 

Kim  3:04  
Oh, okay. That makes sense.

Pam  3:06  
I mean, I could.

Kim  3:07  
Yeah, sure.

Pam  3:07  
And I probably would add 40 to 960 to get 1,000.

Kim  3:10  
Yeah.

Pam  3:10  
And then just left it with 440. That's not too bad.

Kim  3:13  
No. 

Pam  3:13  
But I would have had to actually do something, and I wondered, can I get away with less?

Kim  3:19  
Yeah.

Pam  3:19  
Yeah.

Kim  3:20  
Which, I think that's really cool, that you're like, "I obviously can solve this problem." You have the skill set.

Pam  3:25  
I could go that. I could go down that strategy. But yeah, I really (unclear).

Kim  3:28  
That seems to me that you were looking for like what can I do that's slicker?

Pam  3:31  
Yep. (unclear).

Kim  3:33  
And that is a play that happens.

Kim  3:35  
Yeah, yeah. Yeah, sure. 

Pam  3:36  
Nice. 

Kim  3:36  
Okay, we...

Pam  3:37  
Y'all, we can't wait to see what you do each week. Kim hates it when I take her part. 

Kim  3:40  
No, it's fine. I'm fine.

Pam  3:41  
Join us on MathStratChat and let us know how you think about the problems. And please comment on each other's strategies. It's

Pam  3:47  
awesome when you do that.

Kim  3:48  
It's super fun. Pam posts the problems on Wednesday at 7:00 p.m. Central. And when you answer, tag her and use the hashtag MathStratChat.

Pam  3:57  
Then

Pam  3:57  
join us here to hear how we're thinking about the problem. Y'all, we love having you as part of the Math is Figure-Out-Able movement. Math is Figure-Out-Able!
