In this video segment from Cyberchase, Matt and Digit need to set up tables so that 20 workers will each have a spot at a table in order to assemble their circuit boards. Matt and Digit want to know the number of tables they need so that they can transport them all at once. Matt decides to use small shingles to represent the tables and washers to represent workers. He tests his ideas by positioning the washers around the shingles. Check out "Arrangement 2" and "Arrangement 3" to view Matt's other attempts to solve the problem.

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 were planning a big dinner party for 100 guests, you would need to figure out how many tables and chairs are needed to seat all the guests. How would you go about doing this? What do you have to know about the tables?

Focus: As you watch this video segment, you’ll see that Matt and Digit have to figure out how many tables they need to seat all of the workers. How do they figure this out without actually bringing in the actual tables and workers?
