Strategic Math: Addition Facts 10 to 18

"Addition Facts 10-18 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.

Addition Facts 10 to 18 provides the materials you need to teach addition facts using the concrete-representational-abstract method of instruction, including specific teaching procedures and student materials for each lesson.

In studies, students who scored below mastery on a computation pretest and word problem pretest increased their computation scores from a pretest mean of 49 percent to a posttest mean of 93 percent. The word problem performance of these students rose from a pretest mean of 42 percent to a posttest mean of 87 percent. A second group of students who scored 80 percent or higher on the computation pretest but below mastery on the word problem pretest increased their word problem scores from a pretest mean of 41 percent to a posttest mean of 91 percent.
