One of the 3rd grade courses is "Gods of Greece". When we start reading, he loses focus...He really is not at all interested. While I think it's good for him to know that ancient Greek society revolved around their gods; I don't see the point in thrusting material at him that will only serve to make him hate school.
So I found a book about pirates, which he IS interested in; and we've begun reading that instead. After we read, I ask him questions about the material. He's got a toy pirate ship, and has begun acting out the chapters we've read. I'm sure I can find a good pirate exhibit in a museum not too far from here.
We didn't do the kindergarten program with him, so I'm not sure what it's like. We taught him to read using the Leap Frog "Leap Top" Computer. Kids can learn letter sounds from it, and start spelling 3 letter words. I made a game of it, using a basic phonetic approach: Dad. Sad dad. Mad dad. Bad dad....stuff like that. He loved it.
We're finding the science curriculum to be beneath his ability. He enjoys doing experiments; but I hate to spend time piddlefarting with stuff he already knows. We bought him an circuitry kit and a simple chemistry set for Christmas. I try to incorporate some of the Calvert vocabulary into what he's doing; but if he doesn't learn all those words, he'll be learning others.
