I have decided to use Homeschool Tracker (the basic version is free) to keep track of what we are doing each day. Fortunately where I live requires very little tracking - but we want to keep track more anyway. This seems like a simple way to plan, and track, very inexpensively. Sure, we end up ignoring the grades section - but so far it seems to be working quite well.
While I was figuring out next weeks workboxes, I had a great idea. I've put in all the assignments for each day into Homeschool Tracher.... but I've been having a fun time trying to keep track of what fun stuff to do.
So - here is the idea. Add a "Fun Stuff" subject into H.T. - and for the various ideas, make a resource! So I have resources like "Maze", "Jigsaw Puzzle", "Play Dough". etc. Then if I want to be specific, when I assign it, I use the page/chapter/etc to specify. The cool thing is the resources only show up when I say I want a fun resource. (And when printing reports later, I can choose to exclude the fun stuff subject too)
Basically, I look at the schedule for the day - count how many box activities there are, and then figure out how many fun boxes I need - then pick out that many assignments from the fun stuff subject.
I can later print out the planner sheet for a week - and add in the box numbers. Then each night - fill the boxes as usual.
