Read the book Mouse Shapes by Ellen Walsh.
Early Literacy Aside--Example: As I read the book, you'll notice how we can combine talking about shapes as we also talk about what is happening in the story. Helping children see shapes is the beginning of letter knowledge.

Craft: Have various shapes cut out, the same ones used in the book. Each PERSON gets a blank sheet of paper. Using shapes, they make a picture. Encourage the adults to talk about all the shapes and also about what they are making with the shapes, both their own picture and their child's. The adult or child can write the child's name on their the paper and find some of the shapes in the letters.

Early Literacy Aside--Empower: Playing with shapes is one way to help your child see shapes in letters and to later identify the letters. For example, this is an N the first letter in your name. See how there is a triangle shape between the lines? You will notice many opportunities during your day to talk with your children about shapes.
