Measuring to the Nearest Quarter Inch

About this worksheet

A two-part data worksheet for 3rd grade covering scaled bar graphs and quarter-inch line plots together. Part 1 reads a school garden harvest chart where each unit stands for 5 vegetables: 35 carrots, 25 tomatoes, 15 peppers, and 20 cucumbers. Part 2 turns 10 sunflower seedling heights, measured to the nearest quarter inch, into a tally table and a set of comparison questions. Students verify Maya's claim that 10 more peppers would tie the tomatoes, and the key confirms she is right.

Curriculum objectives covered

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.”

The garden harvest graph and questions 1 to 4, including the two-step reasoning in Maya's claim (15 + 10 = 25 tomatoes).

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.”

The seedling data in Part 2, recorded in quarter-inch units and organized into the tally table before questions 5 to 7.

What's inside this worksheet

Part 1: Scaled Bar Graph: School Garden Harvest

A table pairs each vegetable count with its scaled bar (each square = 5 vegetables). Four questions follow: carrots minus cucumbers with the equation shown, peppers versus tomatoes, the 95-vegetable total, and Maya's 10-more-peppers claim.

Part 2: Measuring Lengths to the Nearest Quarter Inch

Ten seedling heights from 2 to 3 inches (including three at 2 ¼ and three at 2 ½) get tallied into a five-row table. Students then find the most common height, count seedlings at 2 ½ inches or taller, and subtract for the 1-inch range.

How teachers use it

Strand review

Both MD graphing standards sit on one sheet, so use it before a data assessment to see which representation, scaled bars or fraction measurements, needs another day.

Scale emphasis

Before question 1, ask what one square is worth. Students who answer "one vegetable" will subtract squares instead of fives, and you catch it before they start.

Tie talk

Question 5 has two answers: 2 ¼ and 2 ½ both appear three times. Let students argue there must be one winner, then use the tie to define mode properly.
