3. Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one and two
step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw
a bar graph in which each square in the bar graph might represent 5 pets.

3. Apply the area and perimeter formulas for rectangles in realworld and mathematical problems. For example, nd the width
of a rectangular room given the area of the ooring and the length, by viewing the area formula as a multiplication equation
with an unknown factor.

Geometric measurement: understand concepts of volume and relate volume to multiplication and to addition.
5.MD.3
3. Recognize volume as an attribute of solid gures and understand concepts of volume measurement.
a. A cube with side length 1 unit, called a “unit cube,” is said to have “one cubic unit” of volume, and can be used to
measure volume.
b. A solid gure which can be packed without gaps or overlaps using n unit cubes is said to have a volume of n cubic units.
