Classroom Centers (Posters) The Learning Pit Stop is the place you want your Students to stop at. Use these Stations for your classroom learning Centers. Just like a car needs to stop to refuel, enhance, and equip. So must the mind! Tape up these signs with fun duct tape on a tri-fold board and have a mobile center station in your class. Tape 3 sides of the center signs and leave the top side open as a pocket. Use the big pockets for worksheets and the small pockets for task cards, Writing prompts, and Math word problems.
