24 is a great game to work on mental math! I am introducing 2nd& 3rd grade to the primer version of the game over the next week and 4th & 5th grade to the single digit version over the next week. You can order cards to play this game at home. I have also found where you can play the single digit version online or with an app. 

​Thank you to the PMES foundation for buying a tournament kit and playing cards for the math lab! We will have grade level tournaments a couple times this year for third-fifth graders.
