1. Cut multiple pieces in each shape. Demonstrate how to post each paper shape in the corresponding hole. In addition to teaching shapes and colors. This is an excellent fine motor activity as they need to pick up small pieces of shapes using their finger and thumb. Hence works on fine motor skills too.
2. Place the solid wooden shapes in front of your child and ask them to map the 3D wooden shape to the 2D paper cut shapes. This seems easy and intuitive for us. But this uses visual discrimination skills and is very complex work for a 11 month old.
