Scratched braking surface (pics)
Hello everybody!
I was riding my bike a couple of days ago at a moderate pace and suddenly my rear wheel slid into a crack in the road. I was going fast enough to not get stuck and fall, but my rear wheel is very scratched up. Unfortunately I have nowhere enough money to get another wheel(I am a 15 year old kid and have very little support from my parents to bike). So I wanted to ask if there is anyway I can repair the scratches or will I have to survive with these scratches? Thanks!

How do you have a caad9 with no parental support?
I wouldn't try to do anything, it'll only make worse... unless you want to take VERY fine sand paper and LIGHTLY take down sharper edges... but do NOT get carried away. And be prepared to replace pads often.

You can't magically fix a scratch, but that doesn't matter because they won't affect anything. The only problem is if there is a raised burr which can cause your brakes to be grabby.
File off the burr flush to the rim. If you don't have a file you can use sandpaper backed up with a block, or an emery board. BTW- if you do nothing the brakes will wear it smooth eventually.

Thanks for the tips. I guess I will sand the sharp parts and then keep on using them until I can afford a new wheel set!

fishymamba, Cosmetic damage only, judging from the pictures. Clean up the braking surface and save your money.

If you want a new wheel set for another reason, save weight, status, cool factor, or these are trashed and no longer round fine. But there's no reason to scrap these over a scratch. If there's not another reason to replace them keep riding them until there is, regardless of how much money you have.

Be sure to get the sharp bits near the tire.

First off, glad you're okay. Any encounter with the pavement that's enough to chew up your steed's metal is generally enough to chew you up too. So primum prima, it is good that a fellow BF rider escaped unscathed. 
Second, sounds like you've just christened your first pair of training wheels (race training, not "stay upright" training).
The advice you've gotten on sanding them down is sound. If you take care of your rig it will take care of you.
Third, check to ensure that the wreck did not knock the wheel out of true. Spin the wheel with your hand and ensure that the rim has no left/right wobble relative to the brake pads, when viewed from above.
Next, check to ensure that the wheel is not out of round. Spin the wheel again and view it from the side. Does the rim stay the same radius from the hub at all points? You're good to go.
Rock on man.
