Description: Explanations and examples of how to implement the Number & Operations in Base Ten standards in Grade 5. 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. As we go, think about the connections you see between standards, and how you can use these connections to help students build on their previous understandings. Throughout the guide, we'll look at examples of tasks and lessons that focus on students' abilities to look for and make use of structure, as students understand and explain place value and use place value to perform operations.*Teacher Advisor is 100% free.
