4th grade scheduling is a nightmare.  Just when we think we have the groups equally divided into a M/W group and a Tue/Thurs group, we find out that speech/social work has scheduled more than half of the RTI group for that time frame on Tuesday mornings!  So now we  have a M/W group and a Thurs group?  Not sure how that is going to work.  Does intervening one day a week count?
