How to do these

A plant is 10 cm in week 2 and 25 cm in week 4. Find the percent increase

  1. It grew 15 cm.
  2. 15 is what percent of the starting 10?
  3. 15 divided by 10 is 1.5.

The answer is 150%.

Where students go wrong

Dividing by the new value in a percent change. The change is always compared with where it started.

Also called line graph, line graphs, reading line graphs or interpreting line graphs.

What you can put on this worksheet

Read one point
How tall was the plant, in centimeters, in week 2? → 8
The change between two points
By how many centimeters did the plant's height increase from week 4 to week 5? → 2
The greatest increase
What was the greatest increase from one week to the next? → 4
The mean of the values
What was the mean number of visitors per day? → 36
Percent change
By what percent did the number of visitors decrease from Thursday to Friday? → 25%

Questions about these worksheets

Yes. Every line graph sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Pre-Algebra is usually taken around 7th or 8th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the line graph questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 6: read one point, the change between two points, the greatest increase, the mean of the values, percent change and make a line graph from a table. Tick as many as you want and set how many of each, or let it spread them evenly.

Dividing by the new value in a percent change. The change is always compared with where it started.
