I bought individual boxes of jellybeans for my class, but you could just create sample sizes from a large bag to use. It was more expensive to do it my way.... but easier in the long run.
I had students predict how many jelly beans were in each box, then record the actual number. (this could be graphed as well)
Students create their personal graph, then work in a group to combine numbers and create a group graph. Focus on scale needed to graph information (count by 2) and use that information again for a pictograph.
Data for red jelly beans are used for a line plot. (20 students are plotted, if you have more, then just chose the data from 20 students)
Percents and circle graph is intended for 5-8th grade, along with the number sense page.
