But that morning, I was just intent on maintaining an air of confidence—and it worked. I got through that day, and the next, and the next. By the end of the week, I had even learned most of my students’ names. And by the end of the year, I had uncovered a trade secret: Every teacher—no matter how experienced—gets nervous on the first day of school. As teachers, we spend much of the summer preparing for that opening class. We agonize over every detail of the day. We devote countless hours planning icebreakers and introductions; perfecting classroom policies and procedures; and arranging posters and pencils. That first day matters because – to teachers — every day in the classroom matters. And every teacher eventually develops a routine to start the year off right.
