Help. The chain on my Stunt Bike keeps coming off! Emergency.?

sorry. reposted. Wasn't showing the question. Well, I was riding to school today and my chain came off, not once, not twice, three times on my way there. I was unfortunty late for school cause of it. On my way back from school, my chain came off four times..! One time I almost ended up on the road. I have no choice, but to bike to school because I don't live as far. Walking would take me 45 minutes. Biking it's 10 minutes. I can't get a ride. My bike looks fine and it worked perfect when I first got it. I had it for about a week now and I never changed the chain or anything other than the pegs. If it helps, my bike's a Rhino AirMaxx. It's a great, strong bike, but I have no idea what the problem is. My dad took a look at it and saw exacty what I did. Nothing. The chain, the thing the chains attached to, looks completly normal. It usualy alls off when I go down a curb most of the time, but sometimes it's just anywhere. The sidewalk I use is smooth and normal. No cracks or nothing. I check often, and the answer that helps me the most will get 10 points. I need to know because I have to ride it to school tommorow. If I walk I'll be late. Thanks sooo much for your time! I highly appreciate it! It's a real emergency. P.S. Don't tell me to take it to the Bike Shop. Real info only! xoxo. ^_^

Loosen the nuts on the rear axle and move the wheel back and re tighten. http://www.parktool.com/repair/readhowto.asp?id=27
