1) Students finally got their target sheets added what they learned about rational and irrational numbers to the following two targets: "Why do we approximate rational numbers?" and "What is the difference between rational and irrational numbers?"

2) Intro to new PT, each group given one sheet of 8.5x11" paper and asked how many times they can fold it in half.

3) PT- Folding Paper, a task that explores exponential models
  • little to know direct instruction prior, with the exception of explaining "gallon guy"
  • both classes discovered patterns of repeated multiplication and had "lightbulbs" go off about using exponents to shorten the process.
  • first hour independently "discovered" an exponent of zero results in one, and second hour was lead to it
  • first hour started realizing that negative exponents also work duirng number 3, second hour had run out of time

4) Homework: complete number 3 (2nd hour only) and for all - find an example of exponential modeling in your life/real world, etc.
