All of the projects use kid-friendly, no-kiln clay (air-dry, homemade, and polymer) and water-based paints, perfect for home and classroom, plus there's an entire chapter of recipes for mixing up inexpensive homemade clays in the kitchen.
When creating with clay, kids are introduced to a wide range of cognitive and manual skills: they'll work three-dimensionally; make figurative models; use their imaginations in making jewelry and toys; design with color; and decorate with paints.
