Book excerpt: As Miki Murray proves, mathematics vocabulary has the power to enhance the conceptual learning of mathematics for middle school students. It's an essential tool to help them to express their mathematical thinking coherently and clearly to peers and teachers, to share problem-solving techniques, to gain confidence, and to participate in classroom discourse. Murray offers a range of strategies that highlight the important role language plays in the learning of math. Grounded in research and developed from more than 40 years of teaching, reflecting, and learning, Murray's proven strategies are immediately usable or adaptable by teachers.
