## Reflection: Flexibility Rational Exponents - Section 1: Power Sprints

When I gave the first sprint in class today, I didn't tell the students precisely how much time I was going to give them, but I did say that the time was supposed to be short enough that they might not finish.

I was intended to give a full two minutes, but as they raced through the first column of problems I realized that would be too much time.  The last thing I wanted was for a large part of the class to finish before the buzzer because it really kills their sense of urgency and their motivation to beat the clock.  So I decided to reduce the time to 1:30.

One of my students "finished" in the final few seconds, but he made a few mistakes along the way.  Quite a few students were surprised at how many they could answer, and they all seemed eager to try it again.

During the second sprint, which is a little more challenging, I quietly added about 10 seconds to the time just to be sure that most of the class saw some improvement.

Timing is Everything!
