A saw an NXT homeschool package at the Lego Education store and am considering it, however, it's pretty expensive.
I guessed the competitions are heavily populated by boys. I think both girls would do great on a boy's team. However, I also think they would contribute more in a girl's team. Especially DD8, she seems to clam up more around boys. blush
The girls met a young lady who was doing floor science demos at the Science Museum. She was studying physics at one of the city colleges and was involved locally in competion. She was talking to DD's about it and they were really interested in looking into it in the spring.
But perhaps I don't know what I'm getting into. Maybe we should start with the NXT on our own and look at FLL later on down the road.

Thanks much.
