Touch points are great for students to practice their math skills. This packet includes subtraction facts up to 9. For instance, 16-9. Students could subtract independently or with others. There are a different print for each fact. For instance, all the facts for 0 have a zebra print. You glue the subtraction sentence (3-2) on the top of the water-bottle cap. Then you glue the answer on the inside. Each number has touch points on it. Another option is you print it on Avery 6450 8.5 x 11 sheet (circle stickers), which I bought at Avery.com or just use tacky glue.
