# Grade 3: Operations and Algebraic Thinking

1073 questions62 skills

## 3.OA.A.1

140 questions7 skills

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

86 questions4 skills

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

37 questions2 skills

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

61 questions3 skills

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

## 3.OA.B.5

117 questions8 skills

Apply properties of operations as strategies to multiply and divide.

Use associative property to multiply 2-digit numbers by 1-digit

Distributive property

Understand the commutative property of multiplication

Visualize distributive property

Understand associative property of multiplication

## 3.OA.B.6

84 questions4 skills

Understand division as an unknown-factor problem.

## 3.OA.C.7

490 questions29 skills

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.
