Code-a-Pillar coding toy STEM Kit contents

This unique caterpillar features easy-to-connect segments that preschoolers can arrange and rearrange to "tell" the toy how to move: forward, left, right, wiggle, dance, or even wait for a couple seconds before moving again. When children connect the segments to make Code-a-Pillar move, that's sequencing! When they build a sequence that will create a path for Code-a-Pillar to reach a target, that's programming (and problem solving, too)!
