Use this Simply First Math Fact Fluency Strips to help your students master each set of math facts. Each strip is intended to concentrate on subtracting one number to help students work their way up from -0 through -9 facts to differences of 10, to -0 through -19 facts to difference of 20.
As students master a Fact Fluency Strip, move them on to the next. Assess your students subtraction fact fluency by giving them the post-assessment for subtraction facts from 10 and then at the end of their fact fluency mastery for subtraction facts from 20.
Each strip gets more redundant than the next as there are less and less subtraction problems that can be calculated up to the given difference. This will only add to your students’ math fact fluency the more they practice each fact! :)
