Description:

Metric measuring tapes meter sticks and rulers are needed for this activity. After measuring a variety of body parts, students look at the proportions as both rational and decimal fraction to determine which form is easier to compare. The values for each ratio are then averaged to determine an approximation to the actual relationship. Using these values students are then asked to determine the size of a person given the length of a bone.

This activity has been circulating in many forms. It has been adapted to emphasis the advantage of using decimal fraction when comparing values with different denominators. In addition, students find an average value so that they can make prediction as might be the case for an anthropologist or a crime scene investigator.
