Hi! We haven't tried LanguageSmarts yet, but I've become a fan of the Critical Thinking resources in general because they are very logic-driven. Many of the teachers in our family have suggested these materials for GT children, and I know another gifted child at our charter uses a lot of them, too.
Here's the link to LanguageSmarts C, which is for 2nd grade.
http://www.criticalthinking.com/getProductDetails.do?code=p&id=01002 My son is 1 year older than yours (turned 6 in June), and we're going to try D when it comes out b/c he's already met 2nd grade proficiencies. (If we don't leap to MCT first! I'm *still* on the fence! LOL)
We are also using Mindbenders, Word Roots, and Reading Detective from this catalog. My 2 year old has been using Mathematical Resaoning and Beginning Thinking Skills (sporadically and just for fun). If you look around the site, you'll find that there are lots of great sample pages to give you a feel for the materials.
For what it's worth, last year we tried and discarded First Language Lessons (too simple and redundant for us, 'though we used a few of the poems for memorization work), Spectrum 2 and 3(dry and too much writing!), WriteSource 2 (the teaching style didn't give me a lot to work with), and Four Square (MCT would probably have something to say about the narrow structure and prompts!).
As you saw from my other post, I'm thinking about doing Language Smarts D this semester, then moving to MCT. We'll also likely use the grammar piece in EPGY, and we have other specific materials for poetry, latin, vocab/spelling, reading comp., handwriting, and literature. I think the way we'll do this is that "Mondays/Wednesdays are vocab/poetry, Tuesdays/Thursdays are grammar/reading comp.", or something like that. I know, it sounds crazy to list everything, doesn't it?!?
