This page of videos is designed to showcase classrooms in which the NCTM Process Standards are evident. Scroll to video #45, and select the "VoD" box to view the 20-minute Cranberry Estimation video. Second-graders in Massachusetts estimate the number of scoops of cranberries that will fit in a jar. They report, graph, and discuss group estimates with the class as the concepts of range, mode, and median emerge. Observe as the teacher leads the class in developing strategies, learning about new concepts, and sharing and organizing results.

Great activity - need to look a little on the link By bethb on 05/17/2012 - 17:23
When you open up the link it does not go directly to Cranberry Estimation, you must scroll down to find it on the page. Once you find it though it is well worth it. Great lesson idea! I have done a similar lesson around Halloween with pumpkins and pumpkin seeds.
