A crucial teaching point is orientation: the teacher must clarify whether the model represents the Northern or Southern Hemisphere view. Most resources default to the Northern perspective (left side illuminated for waxing, right side for waning).

Despite its strengths, teachers should note a few cautions.

They quickly got into the activity, twisting and turning their Oreos to recreate the different moon phases. The hands-on approach made it easy for them to understand and visualize the concepts, and they were amazed by how accurately they could represent the moon's cycles.
