Grade 3: Operations and Algebraic Thinking

3.OA.A

Represent and solve problems involving multiplication and division.

3.OA.A.1

Fully covered
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each.

3.OA.A.2

Fully covered
Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each.

3.OA.A.3

Fully covered
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.

3.OA.A.4

Fully covered
Determine the unknown whole number in a multiplication or division equation relating three whole numbers.

3.OA.B

Understand properties of multiplication and the relationship between multiplication and division.

3.OA.B.5

Fully covered
Apply properties of operations as strategies to multiply and divide.

3.OA.B.6

Fully covered
Understand division as an unknown-factor problem.

3.OA.C

Multiply and divide within 100.

3.OA.C.7

Mostly covered
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.

3.OA.D

Solve problems involving the four operations, and identify and explain patterns in arithmetic.

3.OA.D.8

Fully covered
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

3.OA.D.9

Fully covered
Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations.
