In this video segment from Cyberchase, Hacker has created a game show called “Find Those Gleamers.” The CyberSquad has to figure out how many power glows are produced by each gleamer bug in order to win the game. Using the information they know about how many glows of power are produced by three gleamer bugs, the CyberSquad uses variables to help them figure out how many glows of power are produced by one gleamer. Then they use this information to calculate how many glows of power are produced by five gleamers.

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: When you are trying to figure out a mathematical problem sometimes it is helpful to make a drawing to better visualize what is being asked. But drawings can take up a lot of space and may take a lot of time, so often it is helpful to use shortcuts. Instead of writing lots of words or drawing pictures, are there any short-cuts you know of to help communicate an idea mathematically?

Focus: As you watch this segment, look for how the CyberSquad first organizes the information they have. Then think about what they do to solve the problem more efficiently. How and why did they use letters? What kinds of operations did they use?
