Math is Figure-Out-Able!
#MathStratChat - April 16, 2025
In today’s MathStratChat, Pam and Kim discuss the MathStratChat problem shared on social media on April 16, 2025.
Note: It’s more fun if you try to solve the problem, share it on social media, comment on others strategies, before you listen to Pam and Kim’s strategies.
Check out #MathStratChat on your favorite social media site and join in the conversation.

Pam 00:01
Hey, fellow mathers. Welcome to the podcast where Math is Figure-Out-Able. I'm Pam.
Kim 00:07
And I'm Kim.
Pam 00:08
And this episode is a MathStratChat episode, where we chat about our math strategies. Wednesday evenings, 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 00:20
Okay, so this week, our problem was 36 plus 48. How would you solve this problem? Pause the podcast. Solve it however you'd like. The problem is 36 plus 48.
Pam 00:33
Hey, you know how other people use MathStratChat, Kim, is sometimes they put it up on their classroom wall.
Kim 00:38
Mmhm.
Pam 00:39
Like on bulletin board and have kids participate. Sometimes they put it in faculty rooms. Sometimes they put in the hallway. We have a teacher friend who has a... Golly, what do you say? Their team is all on a chat, and they put it on the chat, and the people... Yeah, lots of ways that you can use MathStratChat. (unclear).
Kim 00:55
If you were a leader, I would love if that were part of your morning announcements.
Pam 01:00
Mmm, that would be good, huh?
Kim 01:01
Yeah.
Pam 01:01
Yeah.
Kim 01:02
Okay, I'm going to do... I'm feeling kind of Give and Take today. So, I'm going to say that 36 plus 48 is equivalent to 34 plus 50. I take 2 from 36. And I know that 34 and 50 is 84.
Pam 01:18
Very nice. I'm going to think about 6s.
Kim 01:24
Okay.
Pam 01:24
So, 36 is six 6s. And 48 is eight 6s. And six 6s and eight 6s is fourteen 6s. Ew, ugh. Okay, I'm not so happy about 6s.
Kim 01:37
I... Can I tell you what I thought you were going to to do?
Pam 01:39
Can I think about? Can I take it back? Can I think about 18s instead?
Kim 01:42
Sure.
Pam 01:43
I'm going to think about two 18s and three 18s, and that's five 18s.
Kim 01:50
Mmhm.
Pam 01:50
And five 18s is half of ten 18s. Ten 18s is 180. Half of that's 90. Yeah, I like that a lot better. Is that what you thought I was going to do (unclear)?
Kim 01:59
No.
Pam 01:59
No?
Kim 01:59
I thought you were going to do 4s. Nine 4s.
Pam 02:02
4s?
Kim 02:03
Nine 4s.
Pam 02:04
And?
Kim 02:04
Is 36. And twelve 4s for 48.
Pam 02:08
Okay.
Kim 02:08
Because then you have twenty-one 4s. Which is kind of nice.
Pam 02:11
Huh. Twenty-one 4s.
Kim 02:13
Mmhm.
Pam 02:15
Okay. Huh.
Kim 02:18
Yeah, I like these problems. Well done. (unclear).
Pam 02:21
We could do 12s as well, ay?
Kim 02:24
Yeah.
Pam 02:25
Three 12s and four 12s is seven 12s. Which is one of the facts I don't know.
Kim 02:32
Oh, I was going to say that's Cooper's favorite fact.
Pam 02:34
It's 84.
Kim 02:36
Yeah.
Pam 02:36
But I always have to think just a little bit about 7 times 12 and 8 times 12.
Kim 02:40
Huh. Maybe that's why you made this the problem. Maybe it was originally about the 12s.
Pam 02:45
Could have been. When did I write these? Years ago? Okay.
Kim 02:47
I don't know. Alright, well we can't wait to see what you do every week. Please join us on MathStratChat and let us know how you think about the problems. And while you're there, posting your solution, comment on each other's strategies.
Pam 02:58
That is the best way for us to get MathStratChat to more people, and more people can learn that Math is Figure-Out-Able. Ya'll, we post the problems on Wednesdays around 7:00 pm Central. When you answer, tag me, use the hashtag MathStratChat, and then join us here to hear how we're thinking about the problem. Thanks for making math more figure-out-able for everyone that you interact with every day because Math is Figure-Out-Able!
