In this video, Lane and Molly are working together, using a measuring tape to measure their height. The children use world knowledge to guide their discussion about how to measure properly. Notice that each child stands vertically with knees locked, as they work to extend the measuring tape from the floor to the top of the head. Listen to Lane and Molly grapple with which end of the body should be referenced as the total number of inches, the feet, or the head.
