Whether you're a brand new teacher just out of college, new to a country, school, or even grade level it can be intimidating to get started. After all, you're expected by those little people in your classroom to be in complete control and be knowledgeable about everything, even though, just as the kids are learning about you, you're learning about them. When they're not in the room you can panic, ask for help, support from the team or admin, but while they're there, they trust you know what you're doing even though that couldn't be further from the truth. So you gotta fake it, act like you know exactly how kids their age think, act like the little surprises that happen in the day or in your lesson are completely planned out and on purpose, act like you are the the most skilled and resourceful person you know, instead of the frazzled mess you feel like inside. Eventually the act will become the truth as you learn your kids, feel more comfortable in your position and your curriculum, and get to know the inner workings of the school itself. If you do it well the kids won't know the difference and will have more confidence in you as you build more confidence in yourself.
