Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 4. It's likely that a carefully sequenced curriculum map will begin with both OA and NBT standards, as the skills and ideas related to multiplication and multiplicative comparison described in these two domains play a role in many other parts of Grade 4. Throughout the guide, we'll look at many examples of tasks and lessons that focus on students' abilities to make sense of problems and persevere in solving them. As students are exposed to varied contexts and problem types, they will need to think carefully to understand each problem and develop an appropriate solution method.*Teacher Advisor is 100% free.
