Description

This is an activity for children to work in groups. Each child creates a train of interlocking cubes with a specific amount. When the "Snap!" signal is given, children divide their trains into two parts and hide one hand behind their back. In turns, they show the remaining cubes from the other hand. The other children in the circle must calculate the complete combination of numbers.

Materials

10 or more interlocking cubes per student.
