Here's a toy that grows with a child, from infants to pre-schoolers.

As a rolling rattle, it has lots of open spaces for infants to grab. Toddlers can use the 10 pieces to match the shapes on the toy, allowing them to identify shapes and develop coordination and dexterity. Each piece also has a number on one side with the corresponding number of dots on the other to teach preschoolers number recognition and counting.
