There are many types of graphs. Learning to read and create graphs is a very useful skill.
The graph above has a title and a scale. Let say that the circles were drawn by David, Peter, John, Brown, and Jennifer.
The title is "number of circles drawn"
The scale used is the following: one circle represents 5 circles.
David drew 15 circles since we have 3 circles and each circle represents 5 circles.
John drew 7.5 circles. How did we get 7.5?
Note that if a circle represents 5 circles, half a circle will represent 5/2 circles or 2.5 circles.
Add 5 circles to 2.5, give 7.5
