She says his writing is messy and she has been working with him one-on-one to fill in "holes" in his language arts such as the difference between long and short vowels. She says that DS is frustrated by these sessions and tells her that he "gets it" and wants to go back to his seat and work.
I forgot to comment on this part yesterday. I am filling out holes in DS6 math knowledge and his reaction is pretty much the same like your son's
He usually only needs a hint and then he doesn't need more and very often doesn't even want to hear more. For example yesterday we came across improper fractions. He didn't know the term but he knew exactly what such fractions meant, how to simplify them and change them to mixed numbers. "Hole" filled. As long as the teacher can keep the sessions under 1 minute he will be fine anything beyond 3 minutes is annoying
