Flashdiscs were created by a third grade teacher to help students as they practice their basic addition, subtraction, multiplication and division math facts. Flashdiscs are great for students to use in a center and they also work well as a partner activity. Each set of Flashdiscs consists of 12 two-sided discs that cover all the basic math facts 1-12. You are replacing a traditional set of 144 flashcards with 12 discs! Flashdiscs allow the students to see a direct relationship between fact families. They are a self-checking tool which gives the students immediate feedback. Flashdiscs allow the teacher to differentiate instruction for students so they can work at their level.
