Are you working on growing your students' addition and subtraction fluency? One of the most effective and efficient ways of assuring basic facts mastery is to have a system of daily timed assessments that students progress through. Upon mastering one family of facts, they move on to the next. This packet includes 10 addition and 10 subtraction assessments, grouped by strategy. The first 9 assessments are 24 problems, intended to be completed in one minute. 100% accuracy must be achieved in one minute in order to move on to the next assessment. Each assessment is a half-page. The final assessment for addition and for subtraction is a review consisting of 100 problems. Students are allowed five minutes to complete it, and can pass it off with 95% accuracy. Practice pages are included which correspond to each group of facts. Each one is a full page of 100 facts, and great for homework or independent practice. Along with the timed assessments and practice pages, I have included a record-keeping chart so you can easily track student progress.
