Timed Math Drills, Subtraction
Timed Math Drills: Subtraction provides step-by-step practice in subtraction that starts with whole-page calculations using the same, single subtrahend (0 thru 9), progresses to calculations using two different subtrahends, and then to all-inclusive, mixed subtrahends.
The goal is to achieve mastery at the highest possible accuracy level in the lowest possible time. A chart is included on which each student's progress can be recorded. Award forms are included to validate students' achievements.
