Slide 154 / 157 Lab: Foot Measurement Have students work in pairs to trace their own foot. After they trace their foot have them cut it out. Using their foot, have them work together to measure different items around the classroom. Once all students have measured the same few items, call them back together and compare their different measurements and discuss why they got different measurements. Then pass out the standard foot worksheet (see handouts) and have students repeat measuring the same objects from above. When they are done, discuss the results. Click to return to Table of Contents
