## Reflection: Joy Greatest Common Factor - Section 1: Do Now

My students enjoy when I start off a lesson with something that seems completely unrelated to math.  It catches them off guard and relaxes those students who are lower level math students that dread math class.  It's also a great opportunity to build excitement and to encourage students to work together.

By the time I began the mini-lesson students were focused and ready to discover the Do Now activity's connection to math.
