Word Study: Vocabulary Instruction for Elementary Mathematics (formerly titled Words Their Way(TM) Vocabulary Instruction for Elementary Mathematics) is designed for use by 4th- or 5th-grade classroom teachers. Filled with vocabulary-rich activities and strategies, this handy supplement supports the learning of academic vocabulary so your students will do better when they work in their core math textbook. Hands-on teaching units address 3 areas of study covered in a typical math class or textbook: geometry, measurement, and numbers and operations. Each unit provides specific directions, language, reproducible materials, supporting activities and assessments to help you effectively target the important content objectives you already teach, and reflect the expectations of your state or the Common Core standards.
