Using What Works: Strategies for Developing a Literacy-Rich Environment in Math is a close look at how strategies that have been successful in language arts can be reimagined and used within a mathematics environment to support students’ achievement in math. This book shows how a holistic approach to instruction and learning, focused on developing literacy skills across subject areas, can benefit both students and teachers — and change the culture of a mathematics classroom.

Using What Works includes many varied and diverse practical strategies that teachers can use immediately. The strategies presented are designed for a 21st century classroom and integrate technology, individualized learning, and inquiry‑based learning seamlessly and practically.
