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 Interpret the factors as representing the number of equal groups and the number of objects in each group.
NC.3.OA.1.b 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 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 Illustrate and explain strategies including arrays, repeated addition or subtraction, and decomposing a factor.
NC.3.OA.3 Represent, interpret, and solve one-step problems involving multiplication and division.
NC.3.OA.3.a Solve multiplication word problems with factors up to and including 10. Represent the problem using arrays, pictures, and/or equations with a symbol for the unknown number to represent the problem.
NC.3.OA.3.b Solve division word problems with a divisor and quotient up to and including 10. Represent the problem using arrays, pictures, repeated subtraction and/or equations with a symbol for the unknown number to represent the problem.
Understand properties of multiplication and the relationship between multiplication and division.
NC.3.OA.6 Solve an unknown-factor problem, by using division strategies and/or changing it to a multiplication problem.
NC.3.NF.4 Compare two fractions with the same numerator or the same denominator by reasoning about their size, using area and length models, and using the >, <, and = symbols. Recognize that comparisons are valid only when the two fractions refer to the same whole with denominators: halves, fourths and eighths; thirds and sixths.
NC.3.MD Measurement and Data
Solve problems involving measurement.
NC.3.MD.1 Tell and write time to the nearest minute. Solve word problems involving addition and subtraction of time intervals within the same hour.
NC.3.MD.7.b Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving problems, and represent whole-number products as rectangular areas in mathematical reasoning.
NC.3.MD.7.c Use tiles and/or arrays to illustrate and explain that the area of a rectangle can be found by partitioning it into two smaller rectangles, and that the area of the large rectangle is the sum of the two smaller rectangles.
Understand the concept of perimeter.
NC.3.MD.8 Solve problems involving perimeters of polygons, including finding the perimeter given the side lengths, and finding an unknown side length.
Reason with shapes and their attributes.
NC.3.G.1 Reason with two-dimensional shapes and their attributes.
NC.3.G.1.a Investigate, describe, and reason about composing triangles and quadrilaterals and decomposing quadrilaterals.
NC.3.G.1.b Recognize and draw examples and non-examples of types of quadrilaterals including rhombuses, rectangles, squares, parallelograms, and trapezoids.
