Larry,
Opinions on this can be far and wide depending on people's experiences and approaches for this age. Some of it depends on child's temperament and willingness to practice. For example, how long can he focus? What are his other interests that could detract from available practice time?
Finding a balance between keeping it fun while keeping the learning experience moving forward is the trick.
He's probably too young to realize why spending a great deal of time with Stick Control is critical, yet doing the first few pages of the book are both possible and beneficial for a 9 year old as much as they are to a 19 year old.
Speaking for myself, working with that age, I used a combination of resources. A beginner snare drum book such as the Alfred's Drum Method, Book 1 (but there are others) along with the first page of Stick Control. This provides a fundamental concept of reading, intro to rudiments and applied both of these books to the drum set. The old stand-by - Syncopation - can also be introduced by creatively using and adapting the first section of the book to the drum set as well.
Collectively these open the mind for creativity and independence which he can't grasp yet but you are laying the groundwork for longer term... By having such open ended material, it can be adapted to fit his interest and mindset but using these put you in the position of how to apply these to the set. It's not written for you but that's where the creativity and interesting things come about.
Since these are just the "academic" side of things, playing this stuff along to existing tracks make them applicable to music, which in all likelihood is what he may be interested in doing most.
This opens the door to discuss/teach 4 & 8 bar phrasing. Again, he may not be interested in it on those terms, but approaching it to him as play this pattern for 7 measures then play this pattern from your snare book as the fill for 1 measure (and all the combinations that come with this), get's him on the track of phrasing.
It's all in approach and making it not seem so academic but more interesting and exploratory.
Not sure if this is the sort of opinions you are seeking but I can gladly expand on any of it if you want.
Good luck! Starting your teaching with a 9 year old is trial by fire but is certainly possible. Very different than working with adult students (which is all I do these days).
Good, time-tested ideas here, but this approach probably would work better with a slightly older student. In terms of maturity, even a year is a very long time.
Larry, your goal should be to make, and keep, the instrument fun for him. Stick Control can wait. He needs a BUDDY that also helps him learn. Meet him at his interests, which is probably based around the music and/or bands and drummers he likes. His inspiration probably comes from YouTube, so it might be good to bring a laptop to the lesson, so you can check out videos. Teach simple beats and patterns that go along with songs he likes. If he "doesn't like any songs", then explain that he should find some. Even at 9, you can enforce the idea that he participate in his own education (and his parents will love you forever for that!).
Due to his age, he might not yet have the physical coordination that's required of full-on beats and fills, in which case you should simplify. For example, a kick, snare, and hi-hat groove becomes just a kick and snare groove.
You can play musical games, too. Simon Says is a good one. Another is to get out a piece of paper and draw little pictures of bass drums, snare drums, and cymbals in the order of a beat. Point to each picture as he plays to help him learn more complicated combinations.
At 9, he's also old enough to read quarter, 8ths, and 16ths and use a metronome. Get a beginner snare book and go through some pages (I like Vic Firth's Snare Method 1). Don't call it "reading"; call it "timing practice" (because drummers need to practice good timing).
