Integers Speed Test

Once your student understands integer rules, this speed test is the way to make those rules automatic instead of effortful. The 30 problems mix addition and subtraction across all four sign combinations, so there's no skating by on a single pattern. By the end of seventh grade, students should be able to solve any of these in under five seconds with a 90%+ accuracy rate — that's the threshold for being ready for integer multiplication, division, and the rest of pre-algebra.
