I use this "school program" at home for my kids, but I also encourage the teachers at their school to use it.
It gives you a bunch of diff projects that you can due with your kids, integrating art into it and just simply letting their creativity bring them wherever that might be!
oh ya... and its free! I also use the infozone, I have the kids read with me some news articles there, never too early to learn about world affairs!
all the best!
