In this video segment from Cyberchase there is a valuable Encryptor chip being auctioned off that the CyberSquad needs to purchase in order to save Motherboard. At first it looks like it will take about 100 Snelfus to win the bidding and the squad develops a plan to save that many Snelfus in the eleven days they have left before the bidding ends. As Hacker continues to bid, however, the price goes up and the squad must adjust their plans.

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 were saving up for a bike that cost $75. You found a job weeding gardens that paid $10 a day and you figured that within 8 days you would have enough money to buy the bike. Then you find out that the price of the bike will go up to $95 in 8 days. What would you do to adjust your work/savings plan?

Focus: Once Hacker has bid 450 Snelfus for the Encryptor chip, the CyberSquad realizes they will have to change their savings plan again in order to earn more Snelfus. What do they change and how do they decide on their new savings plan?
