My DD's 4th grade teacher is making a big deal out of vocab this year and I'm really pleased...I feel this is something that sometimes gets forgotten in the early grades, and it's a great way for younger gifties to enjoy words. Kids who read way above level can use a little instruction with this, or at least mine can--her vocab seems a bit lacking, considering the books she reads. (Yesterday I had to tell her what "dominate" means, which I thought she ought to know.) I'm not sure she's really trying that hard to get meanings from context.
