Preschoolers age 2 and up can learn while they play with a Geometric Sorting Board. Stack different geometric shapes together based on the number of holes in each. Children will learn to recognize different shapes by using mathematical understanding. Shapes can be sorted by number of sides, number of holes, colour or size. Kids can also develop sequencing skills by ordering the shapes according to colour. This toy is also a great confidence builder as children will feel a sense of accomplishment when they have placed all the shapes in their correct spots. The Geometric Sorting Board from PlanToys is one great developmental toy!
