This is what my door looks like these days – it’s exploded! My students take daily one minute quizzes and when they get 100 % on a quiz, there is a shape for them to color. In my class, suns are multiplication, clouds are division, moons are multiplication and division mixed together and stars are addition, subtraction, multiplication and division mixed together. I have two girls in my class who have almost covered my door. The system as a whole has definitely kept my students focused on learning their facts. Find out how to grab the full set of 4 different shapes to be used as a reward to students who have learned their facts for free from my blog – Raki’s Rad Resources.
