# Grade 3 Mathematics

The focus areas of Grade 3 modules address:

**Operations and Algebraic Thinking**

- Represent and solve problems involving multiplication and division.
- Understand the properties of multiplication and the relationship between multiplication and division.
- Multiply and divide within 100.
- Solve problems involving the four operations, and identify and explain patterns in arithmetic.

**Number and Operations in Base Ten**

- Develop understanding of fractions as numbers.

**Measurement and Data**

- Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects.
- Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Each curriculum module will consist of a high-level outline (curriculum map and module overview/assessment bundle) for instruction and a set of curriculum materials following that outline – including topic overviews, daily lesson plans, extensive problem sets, guiding questions, examples of proficient student work, and other materials. Curriculum modules are high-quality sets of materials for major, supporting and additional clusters in each grade and high school course, developed coherently with attention to progressions in the NYS P-12 CCLS for Mathematics.

The number of modules (between 4-7 per grade) and the time required (between 10 days to 45 days per module) will depend on the scope and difficulty of the mathematical content that is the focus of the module.
