Common Core requires second graders to realize that ten bundles of ten make one hundred. This is going to be an activity in one of my place value math stations next week. Gather up lots of popsicle sticks and rubber bands, a die, and print off the number cards. Students draw a card to determine the target number. They take turns rolling the die and draw that many sticks. When they get ten sticks, they use a rubber band to bundle them. The first person to reach the target number wins the game.
It's a quick game that you can also play with tables or small groups competing against each other.
