This activity combines numbers, colors and shapes into one fun and engaging exercise. The set consists of a baseboard with pegs numbered one to ten with bricks of different colors and shapes for each position. Remove all of the bricks to reveal the name of the shape for that spot, such as square, circle, oval, rhombus etc. Along the front are ten removable tiles with the number in words on one side and numerals on the other. The baseboard measures 48 cm (about 19") long.
