Yes.
I would agree with both PPs. Typical speech language intervention, especially at this age, does not involve pencil and paper. An effective reading/spelling intervention (and there are really only two effective evidence-based decoding/encoding approaches, including variations: OG and LMB) does not have to require writing. Even for spelling. One of the beauties of AAS for spelling is that you can use only the magnet tiles to practice spelling, if you need to, which reduces the fine motor demands substantially, while helping with visual reinforcement of the phoneme-grapheme combinations.
And likewise, the DC for which I used AAS still doesn't love writing, but did go from refusing to do any whatsoever, to completing short answers independently, and even multi-paragraph writing with support (mostly of the motivational kind, these days). And from reading only under duress, to some grade-level pleasure reading. Mine is a little older than yours, but was about that age when we started AAS.
