The Common Core State Standards (CCSS) have been adopted by most states in the United States, and mathematics educators must attend to this widespread adoption and implementation. This book addresses the gap reflected in the statement, "It is also beyond the scope of the Standards to define the full range of supports appropriate for English language learners." This collection of pedagogical practices supports English language learners with the content and language demands of the CCSS for Mathematics. Each chapter highlights, via detailed classroom-based vignettes, specific pedagogical practices that teachers can use to support English language learners with the Standards for Mathematical Practices, and each concludes with questions for reflection and suggestions for action plans.
