We all know that memorizing math facts is a key skill to help students move forward into higher levels of math. Motivating students to memorize their facts is thereby very important. This reward system gives students the chance to color and post a symbol for every level they master. It includes different symbols to recognize the different possible operations (addition, subtraction, multiplication, and division) which makes differentiation simple.
