I don’t want to make this list of must-have materials for teaching preschool too long, so these are only my absolute must-haves! These are the things that make my life easier while teaching preschool. For my preschool teacher style guide, click here. Lanyard. You may have one given to you from your school, but if not, this, for me, is a must-have. Especially one that will break away if a child is pulling on it. I pop my keys on, and I’m good to go even if my clothes that day don’t have pockets!Teacher Journal or other system for recording observations and lesson plans. You can buy my print-at-home teacher planner, but one from Amazon I love is the one from Scholastic. Everyday Preschool In The Classroom. I was sick of long handwritten lists of activities that I’ve used that work every time. Instead, I use this! Every activity is good and simple enough; I can plan at the last minute if I have to. It also makes sub plans so easy; I just make a basic outline and then add in page numbers for the sub to find the step-by-step instructions! No-Spill Coffee Mug I am trying to transition to more green tea this year, but that’s beside the point. My two main things that are must-haves are that the mug doesn’t spill and that it’s cool to the touch on the outside. I am lucky enough to be allowed to have hot drinks in class, but that means I have to be extra careful. I like that this one is not too tall, so it’s stable even when a child bumps into the table it’s on, and cool to the touch when a helpful student wants to bring it to me. Also, because it’s metal, when I take it outside, I am not worried it’s going to get damaged.
