IO Blocks are Guidecraft’s friction fit building system influenced by virtual world design elements. Each of the 11 unique shapes are designed to a 1:1 ratio standard building unit. While playing with the toys, children become familiar with many concepts vital to understanding STEM concepts such as spatial and number sense, structure, and balance. These characteristics make IO Blocks an ideal physical model for introducing children to digital 3D design and product and part creation. This program is open to all ages, whether you’re an expert or beginner. Registration Required.
