Third Grade
Measurement and Data
Solve Problems Involving Measurement and
Estimation.
 3.MD.A.1. Tell and write time to the nearest minute and
measure time intervals in minutes. Solve word problems involving
addition and subtraction of time intervals in minutes, e.g., by
representing the problem on a number line diagram.
 3.MD.A.2. Measure and estimate liquid volumes and masses of
objects using standard units of grams (g), kilograms (kg), and
liters (l).^{1} Add, subtract, multiply, or divide to
solve onestep word problems involving masses or volumes that
are given in the same units, e.g., by using drawings (such as a
beaker with a measurement scale) to represent the problem.
Represent and Interpret Data.
 3.MD.B.3. Draw a scaled picture graph and a scaled bar graph
to represent a data set with several categories. Solve one and
twostep “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.MD.B.4 Generate measurement data by measuring lengths
using rulers marked with halves and fourths of an inch. Show the
data by making a line plot, where the horizontal scale is marked
off in appropriate units— whole numbers, halves, or quarters.

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

3.MD.C.5 Recognize area as an attribute of plane figures and
understand concepts of area measurement.

MD.C.5a A square with side length 1 unit, called “a unit
square,” is said to have “one square unit” of area, and can
be used to measure area.

MD.C.5b A plane figure which can be covered without gaps
or overlaps by n unit squares is said to have an area
of n square units.

3.MD.C.6 Measure areas by counting unit squares (square cm,
square m, square in, square ft, and improvised units).

C.7
Relate area to the operations of multiplication and addition.

3.MD.C.7a Find the area of a rectangle with wholenumber
side lengths by tiling it, and show that the area is the
same as would be found by multiplying the side lengths.

3.MD.C.7b Multiply side lengths to find areas of
rectangles with wholenumber side lengths in the context of
solving real world and mathematical problems, and represent
wholenumber products as rectangular areas in mathematical
reasoning.

3.MD.C.7c Use tiling to show in a concrete case that the
area of a rectangle with wholenumber 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.

3.MD.C.7d Recognize area as additive. Find areas of
rectilinear figures by decomposing them into nonoverlapping
rectangles and adding the areas of the nonoverlapping
parts, applying this technique to solve real world problems.
Geometric measurement: understand concepts
of area and relate area to multiplication and to addition.

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.
