This play-doh cutter can be used for teaching/learning both multiplication and division. This comes in two parts:

1. A 10cm x 10cm cutter with labels 1-10 on two axis.
2. A slicing arm that allows you to place it at any of the marked intervals.

Students can use this to cut play-doh (or trace on paper) any rectangle from 1 to 10 cm on each side. This makes area multiplication models more quickly, thus allowing students to focus on the concept instead of counting 1s cubes with the Base 10 Blocks.
