Frame and Focus: Lock Combinations of Knobs and Keys

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: Let’s say you have a friend who really likes to coordinate her outfits. If she has three different color hats and two different color scarves, how many hat and scarf combinations does she have to choose from? How did you figure this out? Is there any opportunity to use multiplication to help you figure out the number of combinations?

Focus: In this video segment, you will watch Jackie and Matt as they try to find the correct doorknob/key combination to open a high security door. As they test some possible combinations, pay attention to what they do to make sure they try each combination without repeating or missing any possibilities.
