5. THE RESULTS: COLLEGE AND CAREER READINESS STANDARDS FOR MATHEMATICS 57
MATHEMATICS STANDARDS
Multiply and divide within 100.
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. Know from memory all products of two one-digit numbers. (3.OA.7)
Solve problems involving the four operations, and identify and explain patterns in
arithmetic.
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. 16 (3.OA.8)
Identify arithmetic patterns (including patterns in the addition table or multiplication table), and
explain them using properties of operations. For example, 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.9)
Geometry
Reason with shapes and their attributes.
Recognize and draw shapes having specified attributes, such as a given number of angles or a given
number of equal faces. 17 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. (2.G.1)
Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words
halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths.
Recognize that equal shares of identical wholes need not have the same shape. (2.G.3)
Reason with shapes and their attributes.
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share
attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g.,
quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw
examples of quadrilaterals that do not belong to any of these subcategories. (3.G.1)
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the
whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part
as 1/4 of the area of the shape. (3.G.2)
Measurement and Data
Measure and estimate lengths in standard units.
Measure the length of an object twice, using length units of different lengths for the two
16 This standard is limited to problems posed with whole numbers having whole-number answers; students should know how to
perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
17 Sizes are compared directly or visually, not compared by measuring.
