When I’m planning lessons each day, I do not consider myself finished with a lesson until everything I need to teach it is on my cart. So, if I need copies for the lesson, they are in the bin for that grade level. If we are reading a book, it’s on the cart. If I need puppets or stuffies, on the cart. Manipulatives for a game? On. The. Cart.
Like everyone, I am, of course, human. I occasionally realize I left something in my office as I’m teaching a lesson. Luckily, I teach with some amazing teachers and they are always very gracious in covering for me as I run back to grab what we need.
Also, it’s really easy to set something down in a classroom somewhere and not ever think about it again until you need it as you’re teaching days later in another class. It can be challenging to think back and find it again! I try my best to never set things down in the classrooms I’m in and instead always put them down on my cart.
