Free interactive math game: Line Graph Reading — Trends over time. Part of the Statistics category on MathKite.
Taken from the generator that powers this exercise. A fresh set appears every time the page is opened, and the printable worksheet holds ten of them.
Reading values and trends from a line graph.
Follow the horizontal axis to the point you want, then read across to the vertical scale. A steeper line means faster change.
A line climbing from 20 to 50 across a month shows a rise of 30.
Reading a flat section as zero. Flat means unchanged, not empty.
