This is an activity students can do to explore proportionality. This is a lesson for two days. Day one you will read Wilma Unlimited by Kathleen Krull to your students. Students will time each other as they walk, hop, and run 100 feet. Students will then work together to create function tables and graph their data. Worksheets and answer keys included. I hope you and your students enjoy! If you do not have this book, no problem. I know you can find a video of it being read on youtube.
