Not much advice, as we start our homeschool adventure next week. But I already know that DS will be resistant to too much structure or teaching. He loves to learn. He does not always love to be taught. You have my sympathy!
HK, I love the idea of small notes, later pasted into a comp book. I will try this.
Something that has been successful (more or less) this summer is to post a summer-camp-style schedule for the week. Big piece of paper, divided into 5 columns. Lots of pictures, funny writing styles, multiple colors, stars, exclamation points, etc. Even if the content isn't the most exciting, at least the kids know what is happening during the week, and can look forward to something like a trip to a museum or playground. Granted, this wasn't school, but I plan to continue it into the school year and see how it goes.
