"Teaching math at the elementary, middle, and high school level is an involved position that requires patience and a commitment to helping each student achieve success at an appropriate level. Students often need extra attention in this subject, so employers are looking for instructors who not only have a firm grasp of their subject, but can also impart that knowledge in engaging and effective ways. Expect to answer questions about your teaching experience and style as well as how you would handle a variety of classroom scenarios. While teaching credentials are required at public schools, this is often not the case at private schools."
How would you deal with a difficult student who is under-preforming?
I told a story about how I used to teach ESL abroad. On the first day of one of my new classes, a mom came to my office and told me she didn't think her son was smart enough to be in that room, and she didn't want him to feel embarrassed when he compared himself to the other kids. I told her he wouldn't have to worry about that, and stayed a half hour extra three times a week to make sure he caught up. By the end of the semester, he passed with the third-highest grade in the class. Honestly, just tell them a story that demonstrates your patience and willingness to spend extra time on a sensitive problem and you'll probably be saying what they want to hear.
