My kids love to play in the blocks center. We've had some unusual items to use in the center. In a previous post, I talked about having fabric with the blocks. Here are some of my other favorite unusual things we've had in the center.
Straws and Small Buckets - Kids played with the straws and buckets independently and added the straws to a building.
Index Cards - Simple index cards can add some different dimensions to building.
Chenille Stems and a Colander - The kids incorporated the materials in their structure and created things with the chenille stems alone.
