We recently heard a great variation on the I Spy With My Little Eye Game to help children learn their shapes ...
Instead of having your child guess something you see of a special colour (i.e. I Spy With My Little Eye something that is red), ask your child to guess something you see that matches a specific shape; i.e. I Spy with my little eye, something that is round. Reverse roles to give your child the chance to identify shapes first.
Enjoy playing together!
