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: Fractions describe amounts that are less than one whole. If you had a whole carrot and had to share it equally among three friends, how would you cut it up? What kinds of fractions would you have? What if you didn’t want any of the carrot, while one of your friends really liked carrots and you wanted to give her more? How much might you give her?

Focus: In this video segment, watch how Jackie and Inez go about figuring out how to measure out 2/5 of an Electro-Root. Also, notice how the root grows.
