The set's included activity guide comes with 10 brain-teasing challenges, which help kids boost early geometry, critical thinking, and fine motor skills as they build shapes piece by piece. Challenges feature progressive difficulty, and move from simple tasks like building shapes to more challenging tasks like designing and building bridges to help friends cross from one side to the other. In addition to STEM challenges, Geomakers also supports independent, open-ended play; this 59-piece set comes with enough sticks, curves, and connector pieces to help kids build triangles, rhombuses, trapezoids, or whatever wacky shapes they might dream up. STEM Explorers: Geomakers adds hands-on fun to math lessons, and helps kids build shape recognition skills every time they play.
