For someone who is not currently employed as a teacher (I'm actually an Engineer), I seem to spend quite a bit of time in front of a class. My kids are in grade 3 and SK, and I've done various presentations in their classrooms, from an introduction to the solar system, to demonstrations of simple machines. I also help out in some other classes in the school, taking groups of students to do science experiments, math assessments, or anything else that's needed. At various times, I've tutored small groups in math or reading during breaks or after school. Basically, I like to pitch in wherever I'm needed!
