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’ve ever looked closely at a thermometer you may have noticed how the numbers on it are arranged in what might be called a number line. Have you ever seen number lines used in other measurement instruments? If the temperature measured on a thermometer starts at five degrees and then it gets seven degrees colder, what is the new temperature?

Focus: In this segment, the CyberSquad receives information from Motherboard about the moves Buzz and Delete are making with the Council. How does the squad finally keep track of these changes and figure out which floor the Council is on?
