Strategic Math: Place Value: Discovering Tens and Ones

"Place Value: Discovering Tens and Ones 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.

Place Value: Discovering Tens and Ones helps you teach students how to identify the number of tens and ones in a double-digit number using the concrete-representational-abstract method of instruction. The manual outlines specific teaching procedures and contains student tests, progress charts, learning sheets, and more.

In studies, students' scores rose from a pretest mean of 20 percent to a posttest mean of 88 percent. Their mean scores on place value tests were posttest--88 percent; maintenance test--97 percent; and retention test--96 percent.
