Simple shapes make for flexible building. With 150 triangles and squares, a child can make flat patterns, tall towers or enclosed shapes, and take them apart to start again. There is no right answer, so the child decides what to make.
How your child plays with it
- Shape sense — Combining triangles and squares shows how simple shapes make larger ones.
- Planning — Deciding what to build and how to join it builds problem-solving.
- Hand strength — Pressing blocks together and pulling them apart works the fingers and hands.

How to give it the Montessori way
Begin with a small number of pieces on a mat and build a flat pattern side by side with your child. Add more blocks only when they want to go bigger, and leave finished builds out to admire.
