At my school I have to transition kids from my room down to the gym and switch classes with the P.E. teacher. I decided to post markers in the hallway so that I could say "Walk down to the far corner and stop." or "Walk down to the water fountain and then stop there and wait for the P.E. teacher." When I was looking in the closet for a picture or symbol or colored something to hang to mark off the space I came across these posters. I love the instrument family posters (though they rarely get used in my classroom) and decided to hang them at various points along the hallway. Now when I'm walking a class from one place to another I can say to the line leader "Walk down to the harp and stop" or "Walk all the way down the hall until the picture of an instrument from the brass family and then stop."
It's been a really great thing to control the line and free me up but also helps to solidify classroom content. The best part is when you have to stop and address a behavior with a student, or when a second/first/kindergarten student "really has to tell you a very important story" about their weekend. The line can take care of itself and has a natural stopping point. You can walk next to or behind the class and the line leader has a defined place to stop in the hallway. Makes life easier, reinforces content, allows me to breathe a bit more in the hallway between classes... win!
