| Mice in a Cage Videos: | These videos document a Kindergarten class in Florida. The class had recently been working on all of the ways to compose 7 with two whole numbers and addition. One of the ways they did this was by playing "chips in a cup" in pairs. Using 7 counters and 1 cup, one partner hid some (or none) of the counters in the cup, and the other partner's job was to determine how many counters were in the cup based on how many were still visible. This lesson involves a similar idea at a higher cognitive complexity level by determining how many configurations of 7 mice could be in 2 cages. |
