Third Grade mathematics is about (1) developing understanding of multiplication and division and strategies for multiplication and division within 100; (2) developing understanding of fractions, especially unit fractions (fractions with numerator 1); (3) developing understanding of the structure of rectangular arrays and of area; and (4) describing and analyzing two-dimensional shapes. Major emphasis in Third Grade is placed on:

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 – Fractions

• 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.
