My students are expected to have automaticity in their multiplication and division facts. To help them with that, we started taking a 1 minute/20 question multiplication quiz each morning. As students get 100 percent on their quiz, they get to color in a sun, add it to our door and move on to the next level. Here’s a picture of our door right now (sorry about the glare!) You can grab the suns from my Basic Fact Reward Kit for FREE at my TPT store. I also have stars, moons and clouds as part of the set. If you have younger kids, you could just as easily use this for addition and subtraction.
