Here are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.
What is Frame, Focus and Follow-up?
Frame: If you want to measure your height, but you don’t have a ruler, measuring tape, or any other kind of standard measuring tool, how else could you measure your height? What if you could only use a part of your body as a measuring tool? What part would you use and why?
Focus: In this video segment, you’ll see that the CyberSquad is trying to find body matches. Body matches are found when the length of one part of the body equals the length of another part. In some cases, the length of one body part multiplied by a certain number will equal the length of another body part. Use a paper and pencil to write down the body match relationships that the CyberSquad discovers.
Follow Up: What tools, other than their own bodies, do the CyberSquad use to discover the body matches? Measuring with parts of your body or other objects like leaves or pieces of string is called non-standard measurement. Can you think of other examples where you could measure in a reasonable way with a non-standard measuring tool?
