Grade 3: Operations and Algebraic Thinking (OA)

3.OA.A

Represent and solve problems involving whole number multiplication and division.

3.OA.A.1

Fully covered
Interpret products of whole numbers as the total number of objects in equal groups (e.g., interpret 5 x 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 group when 56 objects are partitioned equally into 8 groups, or as a number of groups when 56 objects are partitioned into equal groups of 8 objects each). See Table 2.

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.

3.OA.A.4

Fully covered
Determine the unknown whole number in a multiplication or division equation relating three whole numbers For example, determine the unknown number that makes the equation true in each of the equations 8 x □ = 48, 5 = □ ÷ 3, 6 x 6 = □.

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. Properties include commutative and associative properties of multiplication and the distributive property. (Students do not need to use the formal terms for these properties.)

3.OA.B.6

Fully covered
Understand division as an unknown-factor problem (e.g., find 32 8 by finding the number that makes 32 when multiplied by 8).

3.OA.C

Multiply and divide within 100.

3.OA.C.7

Mostly covered
Fluently multiply and divide within 100. By the end of Grade 3, know from memory all multiplication products through 10 x 10 and division quotients when both the quotient and divisor are less than or equal to 10.

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. Utilize understanding of the Order of Operations when there are no parentheses.

3.OA.D.9

Fully covered
Identify patterns in the addition table and the multiplication table and explain them using properties of operations (e.g. observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends).

3.OA.D.10

Not covered
When solving problems, assess the reasonableness of answers using mental computation and estimation strategies including rounding.
