When is conference time with the teacher? It sounds like she's aware of his needs, is open to his abilities, and is trying to help him. This is huge.
You might want to make a focused, bullet-pointed list about what he can do NOW (remember that she has a lot of students, so keep it as brief as possible). Examples:
* His tested reading level or titles of 3 books that he's read recently. Include AR or Lexile levels (whatever his school uses).
* His current skill level in mathematics.
Personally, I'd ask the teacher for her ideas. What kinds of resources does she have for testing these things so that she can have a formal-ish idea of where he is (e.g. SRA cards, grade-level math tests, etc.)? What are her ideas about helping him?
