It would drive me crazy knowing the schedule of what they were supposed to be doing all the time! It was more than I wanted to think about last year when the teacher explained the system--there are six "specials" classes (PE, computers, art, music, etc.) and they have each one twice during every six day time period. Using a five-day school week. I don't know how anybody knows where their kids are supposed to be at any given time! Every time I dropped by the school for something, he was out of the classroom for something or other.
At least it's not as bad as the neighboring school district, where they decided to set up a system where a kid has a given set of classes on Monday and Wednesday and another set of classes on Tuesday and Thursday, and alternating Fridays between the two. I would have been perpetually in the wrong classroom with the wrong homework!
