From the time my K5-son was a wee babe, I've been encouraged to establish a routine for our days. We are not strict, set-the-timer schedule followers, but I have seen so many good things come out of having a general routine - both for my children and me. And now, five years after our first "routine" was established we have cherished "times" in each day including Bible Time, Table Time, Story Time etc.
When I started planning to "officially" educate K5-son, I wanted our days to flow in the same way they had been. I did not want him to feel a "jerk" into "schooling" and have a big schedule change. Therefore, I fit our "schooling" times into his normal routine, with just a few tweaks.
Our schedule for Term 1 of Kindergarten reflects how I would like things to go. This is our general flow - sometimes the times correspond to the schedule and most times they do not. Having this list printed and on the fridge helps me get back on track if the out of the ordinary happens - which does happen most days. (The highlighted parts of the schedule reflect the "official" 4 hours per day of "schooling".)
When I make up a new routine, it takes a week or two before it becomes habit, so I mostly look at the "schedule" for the first couple of weeks and then after that, the kids generally remind me what we do next.
My kids don't know that the schedule exists. They do know the pattern in which we do things. It makes life easier for me and more predictable for them - and they thrive.
