Ask your kids to show you the moon in the night sky. The sometimes round shape in the night sky is the moon, and it is a source of light to the planet. Does your child know why the shape of the moon changes many times during the course of a month? Explain to them the wonders of moon phases with this simple worksheet. Then, help them solve some math.
