# Grade 3: Operations and Algebraic Thinking

### 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.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.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.
