This game was specifically created to support Chapter 1 of the first grade Go Math! curriculum, but it can be used by anyone to reinforce using bar models to solve addition problems. Students find the missing addends and sums on the activity cards.
Directions: Help the detectives solve the Case of the Missing Number! Match the missing parts and sums to the bar models. Complete a record sheet when you are finished.
Includes 36 bar model cards (12- missing large addend; 12- missing small addend; 12- missing sum).
Additional centers are available! I'm currently working on centers for the other chapters and will update this list as soon as they are available:
