Subject based rather than timetable based.
have a timetable/schedule on the first page and then just each subject area have it's own page- a bit lime when you view it as a day. As you'll know and understand- primary teachers tend to plan the subject for each week rather then each individual lesson for that subject. My planner at the moment on a PDF is 18 pages. I've just started to use this so maybe there is a way.
