Skills Covered

  • Read a line plot marked in halves, quarters, and eighths
  • Find how many, the most common value, and the greatest minus the least
  • Make a line plot from a table of measurements
  • Measure lengths to the nearest 1/8 inch and plot them
  • Add and subtract fractions with unlike denominators from a line plot
  • Share a total equally: total ÷ number of things

How to Use This Pack

Five pages on line plots of measurements in fractions. Page 1 reads two line plots, snail shells in eighths of an inch and kittens in pounds: how many in all, the most common length, how many are longer or shorter than a length, and the longest minus the shortest. Page 2 gives three tables of measurements, carrots, caterpillars and tomatoes, and students draw an X for each one on a line plot; the last line is marked only in eighths, so 1/2 must be found at 4/8. Page 3 measures eight ribbons with a ruler to the nearest 1/8 inch, then plots the lengths. Page 4 adds and subtracts from two line plots, yarn pieces in yards and rain in inches: longest minus shortest, two groups together (1/4 + 3/8), and the total of every measurement. Page 5 shares a total equally: the water in 8 beakers poured out so every beaker holds the same amount, and the growth of 9 bean plants as if each grew the same.

In the Classroom

Measure something real before page 2, such as pencils or cut pieces of string, to the nearest 1/8 inch, and build a class line plot on the board with one sticky note for each measurement. On page 4, have students write the equation they used beside each answer. Before page 5, pour water from three cups into a fourth and back out evenly, so students see the total being shared.

At Home

Measure a few things around the house to the nearest 1/8 inch, such as crayons, spoons, or leaves, and make a line plot on paper. Ask which length is the most common, and how much longer the longest is than the shortest.

Tips for Success

  • Each X stands for one measurement, so count the X's to find how many
  • Line up halves and quarters on an eighths line: 1/2 = 4/8 and 3/4 = 6/8
  • To find the difference, subtract the shortest from the longest
  • To add halves, quarters, and eighths, write them all in eighths first
  • To share equally, find the total, then divide by the number of things

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

  • 4.MD.B.4 Make a line plot of measurements in halves, quarters and eighths, and use it to solve problems that add and subtract fractions.
  • 5.MD.B.2 Make a line plot of measurements in halves, quarters and eighths, and solve problems from it with fraction operations, like sharing a total equally.

Line Plots with Fractions

4th – 5th Grade

A 5-page line plot pack for 4th and 5th grade. Read line plots in eighths (how many, the most common length, longest minus shortest), make line plots from tables of measurements in halves, quarters, and eighths, and measure ribbons to the nearest 1/8 inch, then plot them. Add and subtract the lengths and rainfall on a plot, and share a total equally: if the water in 8 beakers were poured out evenly, how much would each hold? Every page comes in color and in black and white. Answer keys included.
