Math Exchanges

One of the math activities that we frequently do is called a math exchange. We call it this because we are exchanging our ideas around a mathematical topic or concept. The activity begins with a problem that we read together as a crew to make sure that we all understand what the problem is saying. Then we all try and work to solve it on our own. After we have had a chance to think about this problem on our own, we collaborate with a partner to see if their ideas will influence our ideas and vice versa. Finally we end with a whole crew debrief session where we share our ideas and the methods we each used to solve the problem. So much great sharing and learning happens during these sessions. Below are some pictures of our session from last Friday.

 The Problem
