I would recommend using mini-Tootsie Pops so it doesn't take the kids forever to get to the center. I had them stop as soon as they saw any part of the center.
This activity gather data as a class and then students use the data to create a stem and leaf plot, frequency table and histogram. Student will also find mean, median, mode and range.
See my free download, "Tootsie Pop PowerPoint for a hook to get the kids started on this activity :-)
