I wanted a way for my students to be able to brag about learning their multiplication facts! I needed something easily assembled and I happened to have a bunch of colorful circle labels in my classroom. I printed off these empty bubble gum machines and as students master a fact (0-12), they receive a colored circle label. I write the fact on it for them, but they could also write it if you choose. Since everyone might not have colored circle labels on hand, I added some empty circles that could easily be printed on colorful cardstock instead :) Please note, this "idea" could be used for various grade levels in both math and literacy. Students could brag about alphabet letters learned, sight words learned, addition/subtraction facts learned, etc.
