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: Have you ever wondered if it was worthwhile to do a job for the amount of pay offered? To make a decision like that you would probably have to do some estimation. If you were offered $20 to cut a neighbor’s lawn, what kinds of things would you have to estimate to decide whether it was worth taking the job? How do you make a reasonable estimate? What’s the difference between an estimate and an exact calculation?

Focus: As you watch the film segment, note how Franklin is able to decide if he should take on the job. What amounts does he estimate? How does he figure out his profit? Does he have to round any numbers?
