Sidewalk chalk is sometimes expensive and not always easy to find. Mix 1 cup Plaster of Paris with 3\4 cup water and powder tempera paint of your color choice. Pour into an egg carton container, and let harden for 24 hours. Pop the molds out and enjoy. The shape of the sidewalk chalk is easy for smaller hands to use.
You can only purchase the 3 primary colors of tempera paint (red, yellow, and blue) and mix the powders together with the plaster and water to create so many beautiful colors. It makes a great science experiment too for the young ones!
