Breathe: Breathing correctly prepares you to talk in your teacher voice. Your goal is to breathe using your diaphragm. Inhale in a way that puffs out your stomach a bit like a balloon. Then push out the air like you're deflating the balloon. If you take in a deep breath and your shoulders scrunch up, you are not using your diaphragm. Try breathing using your stomach and not your lungs.
Take a Second: Now that you know how to breathe, you now need to take a moment to get into the right mindset. You don't want to start your statement with fillers like "Um". Take a second to gather your thoughts. What feels like a whole minute to you is only a couple seconds to your audience. Don't be afraid of a few seconds of silence.
Project: Congratulations, you're ready to talk! Project your voice in a way that allows all of your students to hear you. Point your mouth to your audience. Be aware that looking down or to the side may muffle your sound.
