Who said playing games wasn’t educational?

Math games give students a chance to get creative and burn a little energy, while reinforcing new (or old!) math concepts in a fun, engaging way.

Some popular math games include:

• Math baseball: Divide students into two teams. The “at-bat” team answers questions to move around the bases, while the outfielders steal questions and earn outs.
• Math facts bingo: Create bingo cards and fill the squares with answers to math questions. Instead of calling numbers, call out equations and wait for them to find the answer!
• 101 and out: Divide the class in half and have each side take turns rolling the die. Groups have to strategize and get to 101 points by multiplying and adding the rolls, without going over.
