The Two-Minute Math Drill series was created to help teachers and parents monitor student progress in operations skills. This book focuses on fractions and decimals. It is a great tool to improve student efficiency in absorbing math facts by making use of timed two-minute drill exercises. Students learn one skill at a time and must master each assignment before moving on to the next timed drill. Each exercise includes a brief review of the skill offered in the last timed test before parenting problems involving the new math fact. The first half of the book reinforces operations skill with decimals; the last half focuses on fractions.
