I use this game in two situations: to motivate my students to finish their work and whenever I have an extra 5-10 minutes. My students always want to play it, and once it becomes too easy we switch out the cards for extra ones (they help me decide when it’s time to switch them out).
There are 24 cards for each set and 6 different sets. They can be switched out every 6 weeks or whenever they become too easy for your students. I prefer to print each set (2 pages) on a different color, laminate them, and put each set in a bag marked according to set number and level of difficulty.
a. First Set: Addition and subtraction (fact families)
b. Second Set: Addition (Equivalent results)
c. Third Set: Subtraction (Equivalent results)
d. Fourth Set: Equations with a missing number
e. Fifth Set: Addition with a missing number
f. Sixth Set: Doubles plus one and doubles
