Good exercises to do at home to lose weight?

Hi, I am 17 and I am 5'4 and 152-151 pounds. I was wandering if anyone knew any good workouts that I can do at home. I would like to lose at least 10-20 pounds before my school starts up next month. If you can tell me the workout and how many of them I should do at a time, that would help a lot. Please and thank you!
