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. Another type of graph is the line graph. Line graphs are helpful in showing information over a period of time. For example, if you want to measure how tall you are at different ages, you can use a line graph to show your steady increase in height. The final graph you will learn about is actually called a pie chart. This is because it looks like a pie! The sizes of each "slice" depend on your data. If you interview 100 students about their favorite pet, and 50 of them like dogs the most, then half of the pie would represent students who prefer dogs.
