Excerpt 1: Cluster 3.OA.A: Represent and solve problems involving multiplication and division. (Pages 4-13)

Description: Explanations and examples of how to implement the Operations & Algebraic Thinking standards in Grade 3. In Grade 4, the Operations & Algebraic Thinking domain describes some of the important expectations around multiplication and division and problem-solving. The NBT standards describe the place value strategies and articulate the size of the numbers being multiplied and divided in word problems. 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.
