Pie Graph 🟪 A pie graph shows how each part of something compares to the other parts and to the whole “pie.” The graph below shows what part (or percentage) of the total number of guppies is contained in each grade’s aquarium. For example, if there were 100 guppies in the whole school, the 5th-grade class would have 62 guppies, because 62% of 100 is 62.

Quick Guide to Graphs

• Every graph has a subject—just like a paragraph.
• A bar graph compares things at the same time.
• A line graph tells you how things change over time.
• A pie graph shows how the parts of something compare to one another and to the whole.
• Some graphs repeat information you already read somewhere on the page; other graphs tell you more about a topic.
