This is a great mini-project for students to practice collecting data, entering data into a spreadsheet, and finding measures of center.
A great extension activity would be to have them create different data displays using their data. Extension activity pages are not included with this resource.
See preview for the lesson plan.
Included in the Zip folder are PDF copies of all handouts, lesson plan with step-by-step instructions (detailed so a sub could potentially do this), and an excel file ready for students to input data. Excel file was created in Google Sheets, so should easily be able to upload to Google in you choose to share with your students that way.
