An update:

We're still working on it, but it looks like we're being foiled by class size restriction laws. frown Here in Fl there is a size restriction of 22 in grade 6 and since the gt language arts class is considered as an honors level language arts class, rather than as an enrichment class the size limit applies.
We're still working on it though to see if there is a legal way around this though. We will have to be creative, but we'll see what we can do. confused
The teacher of the class is willing to allow DH to use all of her curriculum and her website and teach it to DD at home while she acts as a guide, so that may be the way to go.
More later, once it is finalized.
