We made a huge gumball machine with 100 puffballs on it. My students also filled out a gumball sheet with 10 machine hold 10 gumballs each found here.
My FAVORITE activity was making our 100 year old people. While we were brainstorming what 100 year olds would look like, one of my students said "they have cracks in their face that might make their lips fall off!! We made those "cracks" using torn paper. They turned out so cute.
All of the kindergarten students worked together to make a 100th Day quilt. Each student decorated at least one number however they wanted.
