In this video segment from Cyberchase, the CyberSquad analyzes the bar graph data showing the number of bugs in each room in the Cybrary. After comparing their bar graph to the one created by Hacker, the CyberSquad realizes that the issue may be a difference in scale. This segment is the second of three segments. Check out “Inventing Bar Graphs” to see how the CyberSquad created their bar graph. Watch “The Power of the Whole Picture” to see how they explain the difference between the two graphs to Ms. Fileshare.

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: Think about bar graphs you have seen. What are the different parts of a bar graph? What parts are labeled? How are numbers used? What do the bars mean?

Focus: In this video segment, the CyberSquad compares their bar graph to Hacker’s. What do they notice is missing from their bar graph? What do they mean when they talk about the “scale” of the graph?
