The interlocking pentominoes can be fit together in a variety of ways and are a fantastic STEM (science, technology, engineering, math) learning toy that can help your child develop the basics of building, as well as counting, sorting, shape and color recognition. The blocks are also great manipulatives for encouraging the development of fine motor skills and hand dexterity. Constructed from Poplar wood, the pieces are durable and safe, and they also come with their own convenient play tray for easy cleanup and travel.Details:Rainbow40 piecesSupports STEM learningIncludes play trayWoodenFor ages 3 and up
