## 3.OA.3

Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. (See Glossary, Table 2)

### PARCC Examples of Opportunities for In-Depth Focus

3.OA.3  Word problems involving equal groups, arrays and measurement quantities can be used to build students’ understanding of and skill with multiplication and division, as well as to allow students to demonstrate their understanding of and skill with these operations.

### PARCC Examples of Major Within-Grade Dependencies

Students must begin work with multiplication and division (3.OA) at or near the very start of the year to allow time for understanding and fluency to develop. Note that area models for products are an important part of this process (3.MD.7). Hence, work on concepts of  area (3.MD.5–6) should likely begin at or near the start of the year as well.
