Use the lights and flicker them for quiet. "I spy" is a great game for when you and the kids are stuck waiting for something. The only way to survive is to have detailed plans. Try your lessons to see how long they will take. Have a few extra go to lessons if you need them. One of the most amazing Pre k teachers I got to work with had two games she did on a regular basis. Take a tray and put items on it, show the kids the tray then cover with a blanket, sneek your hand in an take one or two items and have the kids tell oyu what is missing. The second game - Gather your kids on the carpet and give them one, two or three step directions. "Please Go to blocks and bring me a blue square." Remember to respect the kids and treat them like people. Look in every child's eyes in the morning. You will get to know if they are tired or feeling sick or need a little love. Try and give them time to talk to you. Kids will trust you to protect them. Make sure you get your circle time routine down cold and do it the same every day. Good luck, it is a great job!
