Although at this point in my career, I generally only make overview notes for each lesson in my dayplan, and therefore, only have one page per day, I try to make the outline user-friendly for myself and detailed enough for supply teachers in my classroom.
In general, I begin the first weeks of school with a fairly open- ended dayplan, just something to get me started, and I hand-write duties in, until the duty schedule firms up.
Within a few weeks, I incorporate teaching blocks to accommodate individual & small group instruction for Daily 5/CAFE. I also include my duties so that they are clearly marked for each day, and I don't have to write them in by hand, even for a supply teacher...
...Soon, I am once again re-creating my daily plans, this time with ESL/ISSP support, reading buddies and library exchange periods built in, so that I can take these special times into account as I am developing my weekly and monthly plans.
My day book as a teacher has gone through many incarnations since I first began teaching in the late 90s... I so love the templates I am able to create, and the fact that they are easily modifiable year to year or even month to month as schedules or philosophies evolve; I cannot imagine the struggles of my predecessors who had to do this work without the assistance of a computer!!!
