I guess if that method of instruction works for your child than it's worth the $. I know for us it would be a total waste. If we ever got to do one activity just once if at all, that would be a miracle. My two sons don't like any sort of repetition or hands on learning. They just want to be shown something and move on. I have a ton of stuff I've accumulated over the years thinking they'd use it and they never wanted to do any of it. We are considering homeschooling too but no formal curriculum. Just want to make sure they are at and beyond whatever would be appropriate for their grade level in our district and the rest would be up to them and their interests.
