Circle graphs are easy to compare, but band graphs are easy to read.
16. Everything Is Out of 100 139
Some students may have some difficulty with basic observations of graphs at first. Advise them to be on the
lookout for basic errors in reading graphs. For example, with a band graph, students may mistake the bar
closest to 100 on the number line for the highest number in the graph, even though it may not be. Here’s an
example from the graph on the textbook page.
Which season is the class favorite? Winter.
This is incorrect. Because winter is the furthest to the right on the line, and therefore closest to 100, the student
thought it was the highest number. The highest number is actually summer, in the middle of the graph.
Remind students to study each graph thoroughly before answering a question.
