Update...
Sent a clearer version to teacher and received a very kind email back asking for feedback on the supplemental work she sent home. Yay...a dialogue!
The work is way too easy, so that opened up the door to discuss this without complaining. She also asked what math would be helpful for him, so I was able to let her know where Sam is (waaaaaay past tally marks, counting, number lines, and basic addition).
Hope this is progress. I'd like to think it is - she had not yet asked for any feedback previously.
Excellent news!
