Assembled for eager inventors, the Discovery Set includes 5 SENSE, THINK, and ACT Cubelets®. Designed to support kids at home, this pack has tons of building options as kids invent and build robot after robot. Also included are Brick Adapters, Bluetooh Hat, and a micro-USB charging cable. Cubelets are robot blocks that help teach important problem-solving skills – like collaboration, engineering, design, and computational thinking. Why blocks? You can build all sorts of things with blocks. Our world is made of blocks. Wood and brick blocks form our homes. Inside, glass blocks filled with code blocks bend light into blocks of letters that shape our perspectives. And now – robot blocks can help you build better thinkers. The experiences we create for students shape them. Cubelets are designed to help students build cognitive skills. So they can solve the biggest problems and teach all the standards we need to cover.
