Domain - Measurement and Data

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

[3.MD.D.8] - 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.

    Successor Standards:

    • 4.MD.A.3
      Apply the area and perimeter formulas for rectangles in real-world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. (Note: When finding areas of rectangular regions answers will be in square units. For example, the area of a 1 cm x 1 cm rectangular region will be 1 square centimeter (1 cm2, students are not expected to use this notation.) When finding the perimeter of a rectangular region answers will be in linear units. For example, the perimeter of the region is: 1cm + 1cm + 1cm +1cm = 4 cm or 2(1cm) + 2(1cm) = 4 cm).

    Same Level Standards:

    • 3.OA.D.8
      Solve two-step word problems using the four operations for problems posed with whole numbers and having whole number answers. 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. [Note: Students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations)]
    • 3.MD.C.5
      Recognize area as an attribute of plane figures and understand concepts of area measurement.
