Strategic Math: Subtraction Facts 0 to 9

"Subtraction Facts 0-9 manual cover photo"

The Strategic Math Series focuses on how to teach basic math facts and operations to students of any age. Content is built upon the concrete-representational-abstract method of instruction. In this approach, understanding of mathematics is developed through the use of concrete objects, representational drawings, and an easy-to-learn strategy that turns all students into active problem solvers.

Subtraction Facts 0 to 9 provides all the materials you need to teach subtraction facts using the concrete-representational-abstract method of instruction. The manual outlines specific teaching procedures for each lesson and includes student tests, progress charts, learning sheets, and more.

In studies, students with learning disabilities increased their ability to compute subtraction facts by 66 percent and the speed at which they were able to make these calculations by 230 percent. Their mean posttest scores were computation--97 percent; word problems without extraneous information--100 percent; word problems with extraneous information--92 percent; and creation of word problems--82 percent.
