Free Grade 4 Line Plots to Display Data Practice

Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots.

Topic Overview

Definitive Answer: Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Solve problems involving addition and subtraction of fractions by using information presented in line plots.

A **line plot** is a special graph that uses a number line to show **data**. It helps us see how often different measurements appear. We mark each measurement with an 'X' above its spot on the line. It's like putting a sticker for each item! Today, we'll make line plots for measurements using **fractions** like **halves** (1/2) and **quarters** (1/4). This helps us organize and understand information, like the lengths of different objects or the amount of liquid in cups.

Step-by-Step Examples

Example 1: A group of students measured the length of their crayons (in inches) to the nearest quarter-inch: 4, 4 1/2, 4 1/4, 4, 4 1/2, 4 1/4, 4 1/2. Create a line plot to display this data.
  1. Draw a number line. Start at 4 and go up to 4 1/2, marking every quarter-inch (4, 4 1/4, 4 1/2).
  2. For each crayon length, place an 'X' above its matching spot on the number line. For example, for '4', place an X above the '4' mark.
  3. Your line plot should show: two X's above 4, two X's above 4 1/4, and three X's above 4 1/2.
✓ Answer: A line plot with a number line labeled 4, 4 1/4, 4 1/2. Above 4, there are two X's. Above 4 1/4, there are two X's. Above 4 1/2, there are three X's.
Example 2: Ms. Lily's class measured the height of their bean sprouts (in inches) after one week: 2, 2 1/2, 2 1/4, 2 1/2, 2, 2 1/4. Make a line plot to show the sprout heights.
  1. Draw a number line. Label it from 2 to 2 1/2, including marks for 2 1/4.
  2. Go through each measurement and put an 'X' on the line plot above the correct height. If a height appears more than once, stack the X's.
  3. Label your number line 'Bean Sprout Height (inches)' to make it clear what the plot shows.
✓ Answer: A line plot with a number line labeled 2, 2 1/4, 2 1/2. Above 2, there are two X's. Above 2 1/4, there are two X's. Above 2 1/2, there are two X's.
