I use the CK sequence.
I actually found a used copy of the monthly planner since I found that much more easier to navigate/tinker with than the day by day.
So far so good and I find I'm getting a lot done in our week.
ETA. I also use the free lesson plans that they (CK), the Baltimore school, and the Colorado place put online.
There is also a CK homeschool group located at http://groups.yahoo.com/group/ckhomeschoolers/
