2 player game
materials: 4 straws, 6 paper plates (2 large, 4 small), tape
Younger kids - dice and number counters (or paperclips, beans, cheerios, etc.)
Roll the dice, using number counters, kids count out the number they rolled. Then, they place the number counters on the whole plate. They roll again, count out the number with their number counters, and place the counters on one of the "part" plates. Whoever figures out the missing part and places the correct number of counters on the plate first gets a point!
Kids pull two number cards from the pile. They place the larger card on the whole plate and the smaller card on one of the part plates. The first one to figure out the missing addend gets a point!
