After a lot of wavering and indecisiveness, I finally purchased a homeschool kindergarten curriculum for Dana. It's called My Father's World, for those of you homeschooling geeks. It's pretty awesome too as it incorporates some great teaching techniques like "bundling", phonics, lots of reading, and plenty of hands-on fun. Thankfully, it starts out with a transition phase to get Dana and me used to the whole homeschooling thing. The best part--it's not expensive.
We've only homeschooled for two days, but Dana is loving it and he's really excited about homeschooling in general. It's also had some other cool ripple effects. 1) Dana has asked me a lot of questions in the last two days. 2) He's happier and his eyes are lit up. 3) My relationship with Dana is much better, I think because he's getting more encouragement from me and less criticism. He's been so bored that he's been in a lot of trouble over the past few months, so the change for the better is pretty nice.
Granted, we're on day 3, so obviously we haven't gotten very far. I'm sure there will be conflicts, but for now, I'm happy to have the excitement of a new and pleasant thing.
