Reflection: Student Ownership The Real Number System - Section 3: Classifying Numbers Activity


I chose to run this activity as a competition and it overwhelmed me a little bit at first.  It is HARD to keep your eyes on 15 or 16 pairs of students.  I adjusted the number of groups that received points as needed when I couldn't tell who was first or last.  I also realized that I had to be careful to vary my scanning pattern so that I wasn't always catching a certain part of the room first each time.  

My students really got into this Competition.  They were very excited to get their cards into the air.  My favorite part was telling them they were wrong and watching them scramble to figure out why.  I felt like they had a much better understanding by the end of class that they would have otherwise with a less competitive activity.
