This is a quick to make holiday math game for your students to play. It reviews rounding to the nearest 100. Students use number cards or playing cards. They pull three cards and use those digits to make a three digit number. Players round that number to the nearest 100 and cover their answer on the game board. First to cover all numbers wins the game My students have enjoyed using this one. I like that they can manipulate the cards to form a number they need.
