The Small, Medium, and Large Circles, Set II, model 1-08600-00, is a pegboard, form board, and perceptual training activity designed for children who are blind or have low vision. This activity facilitates perception of three dimensions while strengthening manipulative, matching, and discrimination skills. It has a base with three pegs for sorting three sets of four circles with holes in their centers for fitting over the pegs. The three sets differ in circle diameter, and as circle diameter increases, thickness decreases. COLOR: The base is cream and the circles are yellow, light blue, red, and black.
