text: My sons had a weird schedule like this too and I'd suggest that if it doesn't bother your son, then leave it be.  I don't think the school needs a bunch of parents trying to figure their system out and take up their time, that they may not have.  Leave it be.  If there are any quirks, the school will figure it out and fix the problem.  Wait it out while they figure it out themselves.  I'm sure they understand there needs to be time for the child to walk to their other classroom in between time schedules.  I believe they're trying to fit classes into a system where they'll have math one morning, and then math in the afternoon another day because some kids learn better in the morning and other kids learn better in the afternoon.  They're the pros, let them figure it out.  You're not the one who has to follow the schedule and I bet the kids, your kid too, can and will follow it without a problem.  Just hang in there and have some faith in the teachers.  Good luck!
