Represent and solve problems involving multiplication and division.

NC.3.OA.1

For products of whole numbers with two factors up to and including 10:

NC.3.OA.1.a

Fully covered
Interpret the factors as representing the number of equal groups and the number of objects in each group.

NC.3.OA.1.b

Mostly covered
Illustrate and explain strategies including arrays, repeated addition, decomposing a factor, and applying the commutative and associative properties.

NC.3.OA.2

For whole-number quotients of whole numbers with a one-digit divisor and a one-digit quotient:

NC.3.OA.2.a

Fully covered
Interpret the divisor and quotient in a division equation as representing the number of equal groups and the number of objects in each group.

NC.3.OA.2.b

Mostly covered
Illustrate and explain strategies including arrays, repeated addition or subtraction, and decomposing a factor.

NC.3.OA.3
