Large Group (Heidi):

 * Trading game going backwards: solve some problems about the trading game going backwards, and play all together as a large group. Use cubes instead of Base-Ten blocks. Have students work in pairs and begin with 50 (they make 5 groups of 10). Then go backwards and take away, going about five times as a whole group before they go off to work in pairs.

Small Group (Maria):

 * Play Plus-1 bingo or Plus-2 bingo
 * Solve a few story problems on paper and show work
