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.Research: Place Value: Discovering Tens and Ones
