Thanks, Paul, for alerting me about this thread,

I don't spend as much time cruising here as I used to.
Chris, we have homeschooled our kids from the beginning, our oldest well into high school. I have used all sorts of things out there over the years. I have primarily relied on Orthodox religious educational materials.
The Catechesis of the Good Shepherd which Daniel alluded to and which Subdeacon Paul has worked hard on to modify for Greek Catholic use is excellent, and I wish it had been around in that form 15 years ago. As with most Montessori-approach programs, there is much hands-on, the kids have a mini-church, etc. etc. This really interiorizes the material as the child combines the sensual and gymnastic with the academic.
There's far more specifics I can go into about the plusses and minuses of specific programs, Catholic and Orthodox, and to avoid me boring everyone you can send me a PM if you want more info.
