he's there I'm sure, but it does sound like you have work to do. Maybe approach math from a more play-based angle for now to tempt him back into it. Math fact sheets had my ds8 thinking he was not good at math- now that we have been de-emphasizing that stuff he is all over geometry, etc.
Don't ignore the trouble listening though. This could be boredom, or another learning issue which will need to be followed up on.
