The activity set I would choose from is stars.
As I have stated in previous posts I like t use a story or song as a starting point for my lessons. My students at times find it hard to engage with lessons. I find stories and songs capture their attention. I would use the story ‘How to Catch a Star’ by Oliver Jeffers. As I teach an autism class, I sometimes use the physical storybook and a youtube version of the story as some students like to feel and touch the book and others like to watch it on the screen. Once we have watched the story and identify the topic as being stars, I would use a tuft tray to examine and play with types of stars. I would use popsicles for some children to create stars, others may like to use their fingers in sand to draw stars with support. One of my students loves space so I would differentiate his lesson further to involve constellations. He is very good at making planets out of playdough and paper so I like the idea of him creating his own constellation. I think he would really like this idea.
I would again use stars as a topic throughout many lessons such as music with Twinkle Twinkle as a previous participant has mentioned. Maths for shape and counting stars, grouping stars of different colours together. Art I would use the idea mentioned in Lots of Stars article of using a splatter painting screen and a tooth brush to create a Starry sky. We could display our finished pictures and compare them to a photograph of a starry night.
