Narrative:

Prior to takeoff clearance; run-up was completed and no errors/problems were detected. After receiving clearance; student and I taxied for takeoff and student went full power announcing 'takeoff power set; engine instruments green; airspeed alive.' I then verified everything was correct and we started our roll. After rotation and at about 10-20 feet off ground (still in ground effect) I noticed a roughness in the engine and immediately took controls from the student. I then closed the throttle; flared; and landed on the remaining runway. At this point; I advised tower we were aborting the takeoff. We then taxied off the runway back to operations and secured the airplane. No one was injured.

Title: A PA28-181 engine began running roughly at about 10 feet after takeoff; so the instructor took command of the aircraft from his student; landed on the runway and taxied to the ramp.
