NCTM: Illuminations: Bar Grapher

If you are like most teachers, you are always looking for new and creative ways for your students to create graphs. On this site students can select from pre-made data sets and explore the concept of bar graphs. In addition, students can enter their own data and see how the bar graphs change with their data. The site allows students to adjust both the x and y axis and change the thickness of the bars. This is a great, easy tool that allows students to explore the concept on their own and create dynamic and visually appealing graphs.
