Miniland's 72-piece set Nuts and Bolts can help children learn colors and shapes, while having fun. Assorted nuts and bolts shaped like circles, squares and triangles, come in bright red, blue and yellow. Kids must match the shapes to put the nuts and bolts together. Figuring out which pieces fit helps children practice problem solving, and develops hand-eye coordination and small motor dexterity. The nuts and bolts come with a set of plastic activity worksheets. Activities have been tested in schools, and highly rated by teachers, for teaching color and shape recognition.
