Math Detectives

My friends were detectives today in Math.  After we did some word problems together, I had my friends try one on their own.  After they finished the problem, I asked them to come up and I checked their work.  They first 3 who had the correct answer became the graders.  The rest of the class took their work to the graders and I helped friends who needed a boost.  We did this 2 times.  Way to go, detectives & graders.
