With the acceptance by many states of the Common Core State Standards for Mathematics, new emphasis is being placed on students' ability to engage in mathematical practices such as understanding problems (including word problems), reading and critiquing arguments, and making explicit use of definitions (CCSSI 2010). Engaging students in mathematics through reading and discussing mathematical ideas is an important means of developing these mathematical practices and the skills needed to be successful in such tasks. Reading is a fundamental skill for learning in all disciplines, including mathematics. Independent readers can gain new knowledge and understanding from reading a variety of mathematics-focused texts. Students' reading abilities also influence their performance on mathematics assessments. In this article, the authors describe benefits and specific considerations for supporting reading comprehension in mathematics and discuss the use of anticipation guides as tools to actively and critically engage students in reading, mathematical reasoning, and comprehension of mathematics text. Their discussion is based on their work with mathematics teachers using literacy strategies in the Literacy Instruction in Math and Science for Secondary Teachers (LIMSST) project. During this four-year project, they observed mathematics lessons, collected lesson plans, and interviewed teachers about their use of literacy strategies.
