Shape sorting with a fun and brain-teasing twist! The set features ten unique shapes and four holes. Can you figure out how to fit ALL the shapes through the holes? Here’s how it works: with the push of a button, the top rotates and all the holes swap places. Kids must explore and experiment to solve this puzzle and fit the holes to all the shapes. Did you do it? Great! It’s time to open the door, get all the blocks out and start the fun all over again. Encourages spatial thinking, fine motor skills, problem-solving, and experimentation.
