2. Build Understanding

Before you get into more elaborate operations, give students some basic tips to help their understanding of
both types of graphs.
Band graphs show how everything adds up to a whole. Think of the different portions of a band graph as little
chunks building together to make one whole thing.
Circle graphs allow you to see how everything compares to everything else. It all forms one whole circle, or
“pie,” but it’s also very useful for seeing how one portion is greater or smaller than another.
