2. Build Understanding
Caution students that although the same color is used for each Soma Cube piece throughout this unit, the
Soma Cube pieces have different numbers in each activity. Also, the Soma Cube pieces are rotated
differently in each activity.
Example: Green shape number 1 is identified as shape number 4 on page 99 in the textbook. It also is lying
flat. These differences will help students become accustomed to visualizing the pieces in different positions.
