I use this blank template to write out the time of my sessions and which students are in my sessions. I write it in pencil since times can always change throughout the year. If there is a time slot that is not on the :00 or the :30 mark, I draw in lines and write the correct times. I stick this in the front of my binder with all of my data but could also be used as a weekly schedule and fill in with IEPs and meetings.
