ABSTRACT
Other chapters in this book emphasize a variety of ways that representational fluency is an important component of students’ models and modeling abilities—and an important part of what it means to understand basic mathematical constructs in topic areas ranging from early number concepts, to rational number concepts, to concepts in algebra, geometry, probability, statistics, or calculus. The purpose of this chapter is to report some ways that the National Science Foundation supported Rational Number Project (RNP) has used the following translation model (Lesh, 1979) to develop curriculum materials and classroom activities that are aimed at helping both students and teachers develop deeper and higher order understandings of some of the most important ideas in the school mathematics curriculum. The Lesh Translation Model. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781410607713/20516923-ca77-409f-a29b-a63a47d73446/content/fig24_1_B.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
