I would use the moon in the classroom in the following way.
First of all I would write the word Space on the whiteboard and find out what the children already know and would like to know on the topic.
We would then look at a picture of Neil Armstrong and listen to a short piece about his life and why he is so famous and we would draw a picture of him.
In the next lesson we would watch a youtube clip of the moon landing and we would take turns re-enacting the first steps on the moon. I think this would be a fun activity for the children and you could maybe have a little areas with blankets, bubble wrap etc where they could practice their walk.
In the final lesson, we would complete a short and simple sequencing activity on the life of Neil Armstrong. Cutting and gluing would also enhance motor skills.
