Thanks for the suggestions!

I posted on here not too long ago about vocab and I was sort of leaning toward something where we could incorporate both spelling and vocab, so I like that idea.

I found a series on Amazon that is "Vocabulary for the Gifted Student" by Flash Kids. It claims to be 1 to 1 1/2 levels up from the listed grade level, but I don't see many reviews.

master of none - I just browsed "wordly wise" and the online part looks great! I'll have to look at the books when I have more time.

HappilyMom - did they just make up their own book or was this something they purchased?
