Are You a Square or a Rectangle?


Tip: Are You a Square or a Rectangle?

How do I do it?
Read the chart directions above and model each step with a volunteer as you go.  Encourage students to problem solve how to measure accurately.  Pair students and have them measure one another and collect their data. Collect, display, and discuss the results, posing questions that arise.

Variations & Extensions
Graph the results and draw conclusions.  Why might our height and arm-span be so similar for many of us?  GIve students standard and non-standard measurement tools.  Have students measure classroom pets of pets at home.  What is the relationship between height and arm-span?  Have students create ratios from their data and compare or plot it on a coordinate plane.  Take the heart rates and plot those along with the ratios and create hypotheses about any relationships calculated.

Common Core Mathematical Practice Standard 5
Use appropriate tools strategically.
