Read any version of "Jack and the Beanstalk" and ask the child to paint his favorite scene from the story. Let the child use tempera paint for a more abstract painting or watercolors for a more detailed one.
In the story, Jack plants a magical bean that grows into a beanstalk. Purchase a flower pot at your local garden store and allow the child to decorate it using paint, paint pens and glitter. Allow her to choose a seed to plant in the pot, and watch the bean grow.
Use beans to create a decorative mosaic. Purchase a mixed variety of beans at your grocery store and glue them on 4-inch by 4-inch square tile. Supervise this activity and use a hot glue gun to hold the beans to the tile. Cover the entire tile or simply create a single shape using the beans. Purchase a wall tile display for the artwork, and put the artwork in your child's room.
