Red: A Crayon’s Story by Michael Hall
This funny, sweet, and colorful book is about a crayon (a blue crayon with a red label) that finds the courage (with the help of a new friend) to be true to who they are. Available at Napa County Library.
Make blue crayon playdoh using this recipe. (Or make regular blue playdoh or use some you already have.)
Re-create any of the pictures from the book using blue playdoh, e.g., a boat, a blue bird, blueberries, blue flowers. Or have your child think of other things that are blue.
Another option would be to draw with blue crayons (find all different hues!) Challenge your child to draw their favorite thing but make it blue for fun!
