Another vote here for "no no, anything but drawing", although of course your DS may vary. Can't speak to the AR stuff, we don't have it here, but we've had trouble getting reading material that's engaging and any challenge at all for DS5 - fiction that's at the right reading level is usually "too scary". Some things that are proving useful to us:
- science books! Is your DS not into science as well as maths? While there are some great maths books, if he's into science as well and his teacher will let him read science books I'd think that would be problem solved. We can tell DS comprehends them because he won't shut up about what he reads, lol.
- once he was sent back from school with a Just William book, which has abstruse vocabulary and also complex "he thinks that she knows that he thinks" situations. This was a problem as he didn't like to interrupt his reading flow to ask for help, but then couldn't understand the next chapter because he'd missed things in this one. So what we did was: he'd read a chapter to himself; then I'd read the same chapter aloud to him, and we agreed a hand signal he'd make if he wanted anything explained. Not ideal - really the vocab was a bit too hard for him here - but this was one of the first books school gave him after they stopped sending him home with reading scheme books, so we didn't want to complain!
- with stuff that's just not very interesting and which he tends to skim, I'm not above requiring him to read a homework chapter aloud instead of in his head, and explicitly making the point that if you're reading something for work you're required to read it well enough that you can answer questions about it.
