We don't do mama-planned topics so much, my planning is closer to what Donna described. I read a LOT & squirrel away information and resources so that when a topic comes up we are (somewhat) prepared to run with it. Our official school year starts on Tuesday although DD & I started last week. We are currently working through:
McHenry's Elements, a seventh grade science text and some assigned science reading (on flight ATM)
Finishing up odd pages from three different SM workbooks while we wait for LoF to arrive. I'll be ordering BA once the budget has recovered from paying all the new term class fees that are due in the next two weeks (if I wait long enough maybe I'll be able to order A-D? Wishful thinking)
A third grade handwriting wb
Music theory
That's all for formal school. DD does most of her LA through free reading & resultant discussion plus self-motivated letter writing and journaling (she always asks for help/guidance or proof reading). I try to make time to play chess or Khet or her new favourite Flux with her and she fills the rest of her day with violin practice, ballet research (i.e. watching her favourite productions and trying to learn the choreography) and fighting with oops I mean playing with her brother.
