Measuring to the Nearest Quarter Inch
Scaled bars and line plots for 3rd grade: a garden harvest where each square is 5 vegetables, and 10 seedling heights tallied to the quarter inch.
3.MD measurement: telling and writing time to the nearest minute and measuring time intervals in minutes.

Scaled bars and line plots for 3rd grade: a garden harvest where each square is 5 vegetables, and 10 seedling heights tallied to the quarter inch.

Elapsed time for 3rd grade with open number lines: reading from 3:15, violin from 4:20 to 5:05, a backwards planetarium problem, and a schedule table.

Read a picture graph keyed at 4 books per symbol, then shade a recess-sports bar graph in fives: scaled graph practice for 3rd grade with two-step problems.

Four tick-marked clocks reading 8:17 to 4:36, then minute intervals on a number line: telling time to the nearest minute for 3rd grade.

Sort 12 items into grams, kilograms, and liters, pick units for a textbook and a watering can, then add 4 kg + 5 kg: measurement for 3rd grade.

Grid rectangles with equal areas but different perimeters, a 7 ft by 4 ft lawn, and missing-side mysteries: area and perimeter for 3rd grade.
3.MD.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.MD.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.”
3.MD.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.2
“Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l).⁶ 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.⁷”
3.MD.5.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.”
3.MD.5.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.”
3.MD.6
“Measure areas by counting unit squares (square cm, square m, square in, square ft, and improvised units).”
3.MD.7.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.”
3.MD.7.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.”
3.MD.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.”
