Scheduling students

As an elementary resource teacher one of the first things I need to do is to create a workable daily schedule for my students.    Creating a schedule depends on what kind of model you work with at your school.  I generally do mostly pull-out with some inclusion. 
 
Creating a workable classroom schedule can be tricky, like putting together a puzzle.  I look at the students I'm working with and their needs (areas that I service them in).  I try and group by grade and ability level as well, while keeping in mind any behavior issues I might have and avoid scheduling some students at the same time (if possible).  Then I look at their classroom schedule and work with their teachers to find the best times to schedule them, so that they'll miss out on as little grade level instruction as possible. 

My schedule is a constant work in progress, as new students come and go during the school year (either transfer ins, or students that are test into special ed. during the school year). 

How do you handle scheduling resource or special education students at your school?

Happy Monday everyone!! ; )
