Hello there-
I didn't homeschool my son at first grade, so I may be off on this. I looked around at a couple of resources and found the average to be in the 1-2.5 hour range. That was even with advanced kids. Have you looked at the Well Trained Mind website? They have an accelerated forum that you might be able to get some more feedback on this topic. I noticed my son at 9 is still pretty dependent on me for school, although that is improving. It's really tough trying to figure out. It just takes a lot of fine tuning for who your little one is. As it is, we've only been doing this for 4 months and I'm still working out the kinks. I wish you well-
