With almost 200 different types of mental math problems in this reproducible book, Mental Math Workouts presents a challenging format that stresses problem solving and the reinforcement of math facts. A glossary of mathematical terms and student assessment records are provided to help the teacher keep track of individual student progress. Each set of activities includes a review exercise, which provides slightly more difficult problems to reinforce covered concepts. Also in this series are Mental Math Workouts, Grades 5-7, Mental Math Workouts, Grades 6-8, and Mental Math Workouts, Grades 7-9.
