Time-wise, in a kindergarten class that's in school from 9-3 they spend an hour eating and playing outside, and hour doing art or PE, an hour in transitions to and from various things and arriving and leaving. So really, there's about three hours of academic instructional time in a day, almost none of which is one on one or tailored to the child's interest. So long as you're aware I wouldn't worry about not having six hours of intense academics.
You've received lots of good suggestions already - I would add something onto Tallulah's great advice. Thinking through my children's kindergarten days, the main focus of instruction *outside* of reading didn't require the children to be reading yet (since most weren't). The kids worked on learning-to-read for about 30 minutes in the morning but that was it - in the afternoon they had a wide swath of time devoted to learning about science or social studies etc type topics that were led by the teacher and usually included some type of art or project work or something experiential. Their teachers also read *to* them everyday and encouraged parents to read aloud to them at night - and their teachers were insisting that we read aloud to them at night all the way through 4th grade even when our kids were reading really high level books on their own. The other part of my kids' Kindergarten days were spent with pull-outs like PE, art and music. The thing I always wished they had more of (and they did too!) were field trips - that's one thing I think I'd work in as much as I could if I was homeschooling a young child - my kids just soaked up so much learning from simply visiting any place at all and seeing something new

Good luck!
