Perfect for indoor or outdoor play, these heavy-duty colorful building blocks will create solid pathways for children to walk upon, tunnels for them to crawl through, or even a playroom to call their own. Because each Careplay grid block is exactly a square foot, they can be used for simple activities that introduce linear and area measurement. Each set includes 48 colorful square blocks, both solid and see-through, plus triangular blocks for pathway corners and pointed rooftops. Ages 1½–5.

Block Dimensions: 12" x 12" x 1"
