My class needed a little extra review on their new math terms today. So I set up a math graffiti wall, armed the students with a marker, and let them at it. I taped 7 sheets of large chart paper to the wall (one for each of our terms). Then I instructed the students to write something related to the concept (in numbers, pictures, or words) on each of the pieces of chart paper. They LOVED it! It was such a fun and interactive way to review! If you haven't already, you've got to give this strategy a try.
