I decided that the easiest way to make the connection for them would be to use "clubs". It was something that was easily relatable to them.
I told them that around the room were five clubs. Each club has very specific requirements. I gave them an envelope (each printed on color coded paper) with multiple copies of various shapes. It was their job to place their team's shapes into the envelopes at each station. If they do it correctly, they will use all of the shapes and will not have any duplicates in any one club.
I found this anchor chart through Pinterest on Lena's Leader's blog and it inspired me to use the "club"theme for this activity. As a class, we later worked to create our own anchor chart that looks similar. However, her anchor chart is SO MUCH better than mine. I hate my own handwriting. It's an annoying OCD thing.
