In this lesson found at http://illuminations.nctm.org/LessonDetail.aspx?ID=L534 students create bar graphs and find the range and mode of a set of data.. The lesson suggests they find out how many of each vowel are in the classroom names, but anything would work. Once collected, they put the data in an online graph. They will need to have a title for their graph and name their x and y axis. There are buttons to choose whether they want it a bar, line, pie, or pictograph. After all information is put in the template, the graph of their choice is created.
This lesson is perfect for many grade levels. Children start graphing in kindergarten and never stop. I will use the application periodically throughout the year.
