In this video segment from Cyberchase, Matt and Digit need to set up tables so that 20 workers will each have their own spot at a table as they assemble circuit boards. They only have five tables, and they found out that when the tables were put together in video segment "Arrangement 1" there were not enough seats for all the workers. Since he cannot add any more tables, Matt realizes that perhaps changing the positioning of the tables will provide the extra seats they need. Check out "Arrangement 2" to watch one of Matt's other attempts to accommodate the 20 workers.

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 had a deck of 10 cards and some pennies and you were laying them out on a table. If you were allowed to put one penny on each side of a card, what would be the best way to arrange the cards to get the maximum number of pennies on the table? What if you had the same task, but this time there was a rule that said every card must be placed right next to another card (so that the sides touch)? How many pennies could you place down? How many pennies could you place down if there were twenty cards? How did you figure it out?

Focus: In this video segment, Matt makes a discovery about why his first arrangement did not seat enough workers. What did he realize? Using the new arrangement, how many workers can sit at a table?
