One strategy here would be to play dumb:
"Wow, I must be having one of those days, because the first time I read your response, I thought you were asking a 9yo child to plan her own education, LOL. Can you please clarify? I would be happy to brainstorm with you, if that's what you mean, since I have valuable insights into DD's interests and personality. Really, anything that allows her to learn something more than how to fill pages with drawings would be a huge improvement, thanks."
All communicated via email, of course, so that there's always a record of what was said, which can go up the chain of command if necessary.
Dude - I actually used a bit of this - not quite as snarky though
!!! I cc'd the principal, the DH, and our psych. as I do with all the emails now. The teacher didn't reply to an earlier letter from our psychologist which asked that the teacher provide enrichment, but she sure did act when the principal got involved (well, she became a bit more involved!!).
