Hi,
I have a similar experience too. My kid is in 1st grade and I had his GIEP meeting last week. His GIEP was even more ambiguous. There were lots of jargons and the teacher did explain everything to me. However, I was not sure what they cover as part of the Gifted curriculum in specific. She also showed me a 2nd grade math book that he is currently independently working on and a few other math tiles and packets. The bottom line is there were no specifics with respect to the curriculum. However, I did not worry much as he would be moving to full time gifted classroom from 2nd grade where he would be learning 3rd grade CCSS.
I would, however, be interested to learn what many of these terms in GIEP mean.
