One of most important things a teacher should leave a sub, aside from the lesson plan for the day, is a current seating chart! So far this school year, none of the teachers whom I subbed for left a seating chart for me. Seating charts are helpful because: students respond better if you know their names students may have IEP and the seating arrangement may be apart of the plan (but without a seating chart-----how does the sub know?) In fact, I have resorted to making my OWN handwritten seating chart for the day because, as a teacher, I believe using students' names frequently (especially if you're a sub) sends the message that you are "with it" and "in charge". Anyone else run into this situation?
