Fractional Exponents, Clip 3, 1:03
- The teacher takes this opportunity to work with an individual group that is struggling.
- She uses a formula they understood to help guide them in this situation. She points out that it is only doubling 1/5th of the time.
- She also points out what is 1/5th, that it is not 1/5th of the pennies, but 1/5th of the time.
- In this case the teacher was explicit with the students. This can be necessary at times depending on time and how many students still need assistance.
