Help your students memorize their subtraction facts! Students are often overwhelmed with memorizing all of the basic math facts. This systematic method focuses on one level at a time. This lessens the burden for students, as they gain confidence with each level they master.
I used these flash cards in conjunction with my "Subtraction Fluency Assessments" download. I handed out 0s and 1s to all students. As each student mastered each level, the next level of flash cards would be provided to that individual student. To conserve paper and copies, students simply wrote each answer on the back after they cut each card. In addition, some pages contain the same problem multiple times to reduce copies (simply cut each card and attach one to the other sheets when distributing to students).
