Subtraction Action!

Unit two of the Math Make Sense program focuses on addition and subtraction strategies, so we're working on applying those skills to problem solving situations. 

We took our first crack at it on Monday with the word problems shown below.  

We did the first problem together as a class and then I had the boys and girls work with their elbow partner on the second problem.  

We covered a lot in just one Math lesson and I wanted to capture it all on video so that the kids could review it not only in class over the next few days, but at home as well.  

Here's a video summary of yesterday's lesson.
