How interesting to hear what everyone is doing! After reading through others' responses I think we're a bit more on the "loose" side of homeschooling, but it's working for us. I want to keep the whole educational process positive and not a chore, which means I have to keep things short. I've found that he absorbs a lot quickly and effectively, but I only have about 10-15 minutes and then the proverbial window is closed!
In the AM when he first wakes up, he does 1 page of his Handwriting without Tears workbook and 2 pages of math (Calvert). That fits nicely within the 10-15 minute time frame that I have to work with.
Usually after dinner or before bed we do some reading. We finished the 'Teach your child to read in 100 Easy Lessons' book last spring, so now we're just doing easy reader books from the library.
That's it for formal, sit-down schoolwork.
Otherwise, we read books about various topics, he collects rocks, he does a lot of art with my very artistic babysitter, he is part of a weekly Waldorf crafting group...he runs around outside a lot...I don't know. It's not all formal and scheduled, but it's working well for us .
