20 min
individual
presentation

Overview

The child uses a box of colored wooden triangles to construct larger equilateral triangles and other figures. This material shows how smaller shapes combine to form larger ones, preparing for area and geometry concepts. The triangular box contains pieces to form equilateral triangles from smaller ones.

Objectives

What the child gains from this work

Compose larger triangles from smaller ones. Develop spatial reasoning and composition skills. Refine fine motor placement of pieces. Experience equivalence of area through construction. Build vocabulary for triangle types.
