Making with magnets!

The Cubelets STEMtrunk

Cubelets are robot blocks that make it fast and easy to engage children as young as four in learning by building robots. There’s no wrong way to build with Cubelets, so it is remarkably easy to transform these blocks into brilliant bundles of robotic curiosity. You don’t need to know how to code or wire to construct robots with Cubelets–just snap the robot blocks together and the magnetic faces do the rest! Every unique arrangement is a new robot with novel behaviors emerging from their construction.
