Description: Explanations and examples of how to implement the Number & Operations in Base Ten standards in Grade 5. These guides are designed to explain what new, high standards for mathematics say about what students should learn in each grade, and what they mean for curriculum and instruction. In Grade 5, the Number & Operations in Base Ten (NBT) domain is composed of two clusters; each cluster has associated standards and is part of the major work of Grade 5, as indicated by the green square. So planning your instruction sequence carefully can ensure your students continue to build on previous understandings.*Teacher Advisor is 100% free.
