Math Sprints Workbooks help students develop mental math fluency. The Workbook consists of differentiated sprints, which may be presented to students as fun, timed games. These sprints will help them build speed and accuracy. The material includes some basic math facts, but mostly goes beyond math facts to other mental math skills. If your student’s mental math fluency is not at level, build their confidence by starting with a Workbook from an earlier grade. The series can supplement any Singapore math curriculum, and is meant for one-on-one instructional use.
