Art is the outlet for little imaginations.  But it also sharpens fine motor skills, introduces colors and textures, and prepares kids for writing. 

Mediums you can use for art include paint, crayons, markers and chalk.  You can make collages, mold clay, even mix food coloring in water.  Your kids can make a mess with glue and glitter, or cut away at construction paper.  The fun is endless.
