Beautiful smooth solid beechwood nesting triangles in the seven colours of the rainbow, with a natural finish to show the grain of the wood. The inner block is a solid 3D triangle. Ideal for construction and imaginative play: to build towers and design rooms or outdoor areas for filling with small world play people or animals; applying mathematical logic to sort counters by colour or size; learning the geometric properties of triangles; exploring size and scale; using mathematical terms - larger, smaller, taller, steeper etc; and improving language skills and broadening vocabulary to describe their activities in action.

Testers commended the open-endedness of the product and their value for exploring a range of concepts - colour, size, shapes, curved and straight - as well as how shapes fit together. A very "versatile and open-ended resource" [said] one setting whose children used them to create patterns and design rooms which they filled with small-world play people and furniture. The shapes are also useful for helping the children to learn colours, shapes and sizes and use mathematical terminology such as "larger", "smaller, "taller" and "wider", which is great for broadening their descriptive vocabulary. "I would definitely recommend them to other settings - and they are a timeless resource that we look forward to using with the children for many years to come!" enthused one tester.
