This activity can be done individually or with a partner. Post the questions around the classroom. Have each student visit each problem, solve it, and record their answer. At the conclusion of the activity, I reveal the answers on the Smart Board so students can check their work and ask questions if necessary.
In order to make it more exciting, you can give students a certain amount of time to complete each problem and have them move in order around the room. Conduct the activity how you see fit based on your particular students.
