This unit will teach the student what the census is about and why it is necessary. Students will take a sample census, process the results, and use Microsoft Excel to prepare pie charts. They will present the results to their classmates in an oral presentation. Materials are organized into two folders, Teachers and Students. The Teacher folder includes lesson plans, useful links, and sample finished pie charts to be used as models. The Students folder includes handouts and unfinished templates to prepare pie charts.
