Do you know what a bar graph is? Or have you ever heard a pie chart? In Graphs for Kids, you and your kids will learn all about four basic graphs that people use to share data. You can use many types of graphs to display the same information. Sometimes it just depends on what you like best. Pictographs use pictures to display data. For instance, if you studied how many students liked a specific field trip, you could create a pictograph to show the numbers. A certain picture would represent each student or a specific number of students. You could use a bar graph to share the same information. Instead of pictures, you would use bars, usually of different colors.
