Resource Schedule

I am a resource teacher and struggle every year with how to best meet the needs of my ever increasing number of students on my caseload.  This year I adapted and idea from the other resource teacher at my school (she's great).  She teachers the younger kids and has them on centers schedule with working with her as one of the centers.  I decided to to this with my students as well.  Now that we are a few weeks into school it is really starting to go more smoothly.  Each student has their name on the wall with their individual schedule underneath.  Next to each time frame is the letter G for Guckenberger, I for independent work, and C for computer.  When students come in they know exactly where they need to go and what they need to do (most of the time).  I am still working on the independent work time.  I find I am taking time away from the students that are having time with me to remind the independent workers what they need to be doing.  I just need to come up with a system that reminds them of their individual activities.  If anyone has any ideas, I would love to hear them.
