I'm a new teacher of middle school mathematics starting in two weeks. I am already prepared for the mounds of paperwork and the difficulties of creating lesson plans from scratch and classroom management as I enter my very first year of teaching. However, given the current economic times, we all know how easy it is for school districts to layoff teachers or deny teachers (who do not already have it) from tenure. My question is, as a first year teacher, how can I go above and beyond to make myself as irreplaceable as possible? I would like to be a valuable asset to the students, their parents, as well as my future colleagues (both teachers & administrators). Do you have any tips on how I can go above and beyond my expected duties (whilst possibly avoiding the infamous teacher burnout)?
