A simple 5 step Brown Stair perfect to introduce in the 0-3 classroom. Consists of 5 rods graduated in proportional increments.
Aim:
To help develop the child's visual discrimination of differences in two dimensions.
To help develop the child's muscular co-ordination.
Indirectly, to prepare the child for later work in geometry through the general observation of the geometrically regular differences in the size of the prisms' edges, faces and total volumes.
