Many wonderful playtime ideas are brought together with this Activity Center & Marble Run wooden cube. In addition to shapes for inserting and a string threading game, there is a marble run, a coordination game to learn numbers, and a wall of gears integrated into the cube. The entire set intensively trains motor skills and understanding of shapes, colors, and physics - but is also a lot of fun! The blocks and balls that are inserted into the cube can be retrieved through a small door in the bottom - and then put back in again. This motor skills cube is a great all-rounder for active young researchers who want to discover the world around them!
