Unit Block System

Unit blocks are the ultimate open-ended toy for play based learning. Rooted in the understanding that children build knowledge through hands-on experience, block play lays the foundation for learning through play. Originally developed over 100 years ago, Guidecraft has innovated on the unit block system to facilitate exploration in light, color, and design. Every satisfying, mathematically-aligned piece seamlessly coordinates, providing opportunities for large-scale builds, STEM problem-solving, child-directed storytelling and more.
