From our teachers' playbook

Full, half, crescent, repeat!

What do 3rd graders learn about the moon?

Third graders learn that the moon does not make its own light. It reflects light from the sun! As the moon orbits Earth, about once a month, we see different amounts of its lit side, and those are the phases: new moon, crescent, quarter, gibbous and full. Kids also learn the moon has no air, is covered in craters, and keeps the same side facing us. The click moment is when a student realizes the moon is not actually changing shape. We are just seeing it from a new angle.

Our favorite ways to teach the moon

The moon is right there in the sky every night, which makes it perfect for hands-on science. These moves turn moon facts into real understanding.

Lamp and ball phases

Darken the room, put a lamp in the middle as the sun, and give each kid a foam ball on a pencil. As they turn slowly in a circle, they watch the lit part of their "moon" grow and shrink. They will see every phase right in their own hands.

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

A month of moon watching

Send home a moon calendar and have kids sketch the moon each night they can see it. Check in every few days in class: "What changed?" Looking again and again over weeks builds a much deeper picture than one lesson can.

Why it works: spreading practice out over days is one of the two most effective study methods in a major research review (Dunlosky and colleagues, 2013).

Sing the moon facts

Play a moon song during morning meeting all week. Then pause the song and let kids finish the fact. Music gives them a hook to hang new vocabulary on, like orbit and crater.

Why it works: a catchy, repeating tune gives the brain a hook to hang words on, so sung text is remembered better (Wallace, 1994).

Questions parents and teachers ask

What are the phases of the moon for 3rd grade?

The main phases are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter and waning crescent. The cycle takes about a month.

Why does the moon change shape?

It doesn't! The moon is always a ball, and half of it is always lit by the sun. As it orbits Earth, we see different amounts of that lit half, which is why it looks like it changes.

Does the moon make its own light?

No. The moon reflects light from the sun, kind of like a mirror. That is why we only see the parts the sun is shining on.

How can I teach moon phases at home?

Go outside and look at the moon a few nights a week and draw what you see. You can also use a flashlight and a ball in a dark room to show how the phases happen.
