Tuesday: 3 Act investigation, cubes

1) Fill in any new information based on PT: Nesting Dolls for the following learning target: When are exponents used and why are they important?  

• Student responses centered around using exponents to find a rule as opposed to using an exponent to simplify repeated multiplication.
  
• For both classes, I planted the idea of using exponents to describe something getting smaller (intro to decay)
  

2) Go over homework answers 1-19 in small groups followed by my explanation for lingering questions

3)  Three Act Task: Cubes

• Kids were completely mystified by the video and somewhat annoyed.  : )
• It's important to have models for kids to use when learning to draw isometric shapes
• We stopped after Act 2 and will complete this task tomorrow
• Video for Act 1 Here

4) Assignment: We did several together from the bottom of yesterday's exponent handout to review substitution then for homework, students complete Odds Only on the side called "Substitution."
