Standard Identifier: 3.MD.6

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Standard:
Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).

Standard Identifier: 3.MD.7.a

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Standard:
Relate area to the operations of multiplication and addition. Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths.

Standard Identifier: 3.MD.7.b

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Standard:
Relate area to the operations of multiplication and addition. Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real-world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.

Standard Identifier: 3.MD.7.c

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Standard:
Relate area to the operations of multiplication and addition. Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b + c is the sum of a × b and a × c. Use area models to represent the distributive property in mathematical reasoning.

Standard Identifier: 3.MD.7.d

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: understand concepts of area and relate area to multiplication and to addition.

Standard:
Relate area to the operations of multiplication and addition. Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real-world problems.

Standard Identifier: 3.MD.8

Grade: 3
Domain: Measurement and Data

Cluster:
Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures.

Standard:
Solve real-world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.

Standard Identifier: 3.OA.1

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7.

Standard Identifier: 3.OA.2

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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. For example, describe a context in which a number of shares or a number of groups can be expressed as 56÷8.

Standard Identifier: 3.OA.3

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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.

Footnote:
See Glossary, Table 2.

Standard Identifier: 3.OA.4

Grade: 3
Domain: Operations and Algebraic Thinking

Cluster:
Represent and solve problems involving multiplication and division.

Standard:
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 × ? = 48, 5 =  ÷ 3, 6 × 6 = ?.
