Checker Math

I thought I would share some math problems that the students in our class are asked to solve.  Students are able to solve these problems on their own or with partners.  The students are given time most days to share their mathematical thinking with their friends.  In solving these math problems the students learned once again that there is more than one way to solve a math problem.  It's always fun to listen to the students discussing a math problem together.  The problems below were solved by Deagin.

7. In a game of checkers each person starts with 12 checkers.  In the middle of their game Blake has 7 checkers left and Brynn has 4 checkers left.  How many total checkers have been removed from the board so far?                           13 squares left
