Prisms for the Brown Stair19 Prisms in a Wooden Box

The prisms for the Gonzagarredi Brown Stair are a set of 19 prisms in a natural wood finish, kept in a wooden box. In size they match the thinnest prism of the Brown Stair. They extend the work with the stair: the child explores and compares the volumes of the prisms and keeps practising the discrimination of size and dimension. The natural wood finish adds a tactile element to the work. It is an addition, not the stair itself; the Gonzagarredi Brown Stair is sold separately. For children aged 3 to 6.
