Red Light/Green Light is two addition/subtraction math games in one and focuses on either addition with regrouping (carrying) or subtraction with renaming (borrowing). It will engage the students plus give the teacher a quick assessment of who understands the process by using visual signals.
The students each have a red light/green light card. Red means stop; regrouping or renaming is necessary before the problem can be worked. Green means there is no regrouping or renaming necessary, and the student can proceed to work the problem.
Since you choose the addition or subtraction problems, they can be as easy or as difficult as you would like.
A list of materials as well as complete directions is enclosed in the handout. An example of how to play the game is also included. This game is suitable for grades 2-4.
