Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects

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.
Sample Activity:

Word Problems: Time Intervals
Also included in 
3rd Grade Math Centers
Time Barrier Game (v. 3)
Time Match (v. 5)
Time Bump (v. 4)

3.MD.A.2 Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step 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.

Sample Activities:
Estimating Weight
More or Less than a Liter?
Also included in 
3rd Grade Math Centers
Weigh it Twice
Marble Grab

Measuring One Liter
Capacity Lineup
Word Problems: Volume and Mass

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 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.
Sample Activity:
Represent and Interpret Data

3rd Grade Math Centers
Graphing M&M's
Gummy Bear Graph
Paper Ball Throw

Jake's Survey

3.MD.B.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show data by making a line plot, where the horizontal scale is marked off in appropriate units- whole numbers, halves, or quarters.
Sample Activity:
Measure to the Nearest Half-Inch 
Also included in 3rd Grade Math Centers
Measure to the Nearest Quarter Inch 
Squid Eyes!

Measuring Strips Line Plot
Measuring Names Line Plot (v. 1)

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.
a. 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.
Sample Activity:
Square Units
Also included in 3rd Grade Math Centers
Square Meters

b. 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.
Sample Activities:
Area on the Geoboard
Find the Area   (N.B. When printing this activity you may need to specify no page scaling so that the exact size is maintained. Some printers by default print pages at the setting 'Shrink to Fit'. Ensure that your printer is set to print at 100%.)

3.MD.C.6 Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).
Sample Activity:
Rectangles with Color Tiles
Also included in 
3rd Grade Math Centers
Cover Your Notebook
Measuring Objects in Square Centimeters
Area Compare 

3.MD.C.7 Relate area to the operations of multiplication and addition.
a. 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.
Sample Activity:
Find the Area of a Rectangle
Also included in 3rd Grade Math Centers
Complete the Rectangle (v. 2)

b. 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.
Included in 3rd Grade Math Centers
Word Problems: Area

c. 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 axb and axc. Use area models to represent the distributive property in mathematical reasoning.
Sample Activity:
Jack's Rectangles 
Also included in 3rd Grade Math Centers
Build Rectangles of Two Colors

d. 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.
Sample Activities:
Find Areas of Rectilinear Figures (v. 1)

Design a Flower Bed
Also included in 3rd Grade Math Centers
Find Areas of Rectilinear Figures (v. 2)
Three Rectangles

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.
Sample Activities:
Squares on a Geoboard
Rectangular Robot
