Moon Phases
Observe and describe the Moon's changing shape over about a month, recognising that it goes through a repeating cycle of phases from new moon (invisible) to full moon (complete circle) and back again
Lesson
Set out your lesson
“Moon Phases means describing the Moon’s repeating phase cycle from new (invisible) to full (complete circle) and back. We will practise once together, then check a fresh example.”
Bring to the table
- Phase cards: new moon, crescent, half, full moon
- Simple month calendar strip
Extra for the adult
Worked example. New moon can look invisible. Full moon is a complete circle. The shapes repeat over about a month.
Optional challenge. For Moon Phases, add crescent or half between new and full.
What to notice. Keep one parent note: phases ordered; month cycle said; support used. This session samples Moon phases, not mastery of astronomy.

Moon Phases means describing the Moon’s repeating phase cycle from new (invisible) to full (complete circle) and back. We will practise once together, then check a fresh example.
Spend about 12 minutes ordering phases, saying the cycle repeats about a month, then checking a fresh phase.

Check understanding
- Describe that the Moon appears to change shape over about a month
- Name or draw at least three phases: new moon (dark), half moon, and full moon
- State that the pattern repeats — the Moon goes through the same shapes again and again
“If you asked your child to look at the Moon several nights in a row, could they notice that it changes shape and describe the pattern?”
