Learning Advantage Color Crystal Block Set

This set of 25 polished, colorful acrylic blocks features 17 different shapes. As kids learn to fit these shapes together, their understanding of spatial relationships, geometric vocabulary, color recognition and congruence will grow. These manipulatives will also spring to life in front of a light panel or a sunlit window. The blocks create colorful streams of light and eccentric shadows. Made from extra thick acrylic plastic, these colorful shapes are designed to last for years. And just rinse them with soap and water for cleaning. For ages 3+. Size of largest block: 3.1"W.
