Phases of the moon in Oreo cookies

Creating phases of the moon with Oreo cookies (or similar chocolate sandwich cookies with white icing) is a good activity for many age groups. For pre-school children, it can be used to teach basic phases of the moon, and for older students, it can help them remember how the moon proceeds around the Earth with respect to the Sun. This activity is covered in many places, such as the NASA spaceplace website.

The worksheet provided below has 4 simple stages of the moon designed to be overlaid with cookies, and shows the procession of the moon around the Earth. Alternatively, you can have students make their own charts.
