Most humans prefer some type of predictable schedule, and children are no different.
Math, history, geography, English, arts, science - pretty-much same time-frame each day. Broken up with plenty of breaks.
And field trips, and usually one or two co-op days a week.
Then it's back into their cages in the trailer....
We were more flexible, letting kids decide as long as all the week’s work goals were completed, didn’t matter what order... But we locked ours in the basement, not a trailer.
