Reflection: Real World Applications Rational Exponents - Section 1: Warm Up


This was the very first warm up I wrote for BetterLesson!  I think this is a perfect way to start this lesson.  It really got the students talking and thinking about exponential models.  A few students stuck with the $200 per day, like Warm Up 1.  Most however, like Warm Up 2, figured out that the doubling pennies would be much better in the long run.  After my students completed this warm up, I lead a class discussion.  I asked who would be willing to share their opinion and called on volunteers.  I find that this language is powerful as asking for an opinion rather than asking for a correct answer takes some of the pressure off and more students tend to raise their hand.  They were excited to share and some expectation for set for what they would see in this unit.
