Your students will beg to play these engaging games—racing the clock or each other, or they can “play” on their own. You don’t have to tell them that what theyre really doing is practicing number bonds (aka fact families) and developing mathematical reasoning.
Use these games with a Singapore Math program or with any other math curriculum, and make math come alive for your students!
