Order the Moon Cycle
Start with a New Moon you cannot see, then Waxing (growing), Full Moon, and Waning (shrinking). The cycle repeats.
Reading
The Moon orbits Earth. Sunlight hits the Moon at different angles, so we see changing shapes. A New Moon is dark. A Waxing Moon grows. A Full Moon looks like a circle. A Waning Moon shrinks. The cycle is cyclical and repeats.
Tip: New Moon -> Waxing -> Full Moon -> Waning -> repeat.
