Constructive Triangles
The Constructive Triangles have a new companion! Discover our new Constructive Triangles with Task Cards.
The Constructive Triangles consists of a set of 5 wooden boxes that progressively introduce children ages 3-5 to the different shapes that can be formed with various triangles. Although the material aims to introduce math concepts, it is considered a sensorial Montessori material. Geometry is introduced through the children's senses using bright colors, sharp edges, and bold eye-catchy outlines to guide eyes and fingers.
Through the Constructive Triangles, children intuitively learn how to form new shapes, such as rhombus, parallelogram, trapezoid, and hexagon, using various triangles. Following the formal presentations, you can reinforce children's knowledge by encouraging them to interact with the materials using our new Constructive Triangles Task Cards.
This product includes a downloadable lesson plan.
