I would choose the activity set: The Moon as the moon is something the children can easily point out in the sky.
I would begin the lesson by asking the children to draw a picture of the moon. I imagine I would get a lot of variety. I would ask the children to describe their moon to their partner and ask what time of day is their moon showing at. The children could discuss why they drew their moon the way they did eg full moons, crescent moons etc.
I would give the children a template of ‘What does the Moon Look Like’ and get them to fill it in for homework once a week over the following four weeks. In school, the children would discuss any changes that came over the moon since last weeks drawing.
I would do an art lesson with the children based on the different phases of the moon with a focus on the light and dark colours. The children would label the moons they’ve done in their art lesson with the correct terminology:new moon, full moon, first quarter, last quarter.
