## Reflection: Joy Number Tricks - Section 2: Math Magic

As students started to talk with their group I started to hear “Wait, you got 3 too?”  and “Everyone got 3!” and “Why did everybody get 3?”.  This trick excited students and got them asking great questions and looking for connections.  It also motivated them to dig into the mathematical reasoning in the next section of the lesson.  The next day a student told me that he had enjoyed using the trick on his younger brother.
