Narrative:

While practicing touch and goes with a student; after touchdown the student released back pressure on the yoke dropping the nose; this put the aircraft in an attitude that almost flipped the plane sideways. She proceeded to apply back pressure and right rudder since the airplane was veering left; this sent us heading right towards the edge of the runway 35L; I proceeded to take over the controls; applying full power and trying to rotate the aircraft before it flew off the side of the runway; and in the process; the left wing tip and left elevator tip appeared to struck the gravel (I did not notice this while in flight). I managed to rotate and stabilize the aircraft and proceeded to fly the pattern again and come in for a full stop landing. I failed to run a thorough post flight and did not notice the damage to both the wing tip and the scrapped elevator tip. Also on sunday I went out with a different student for a flight and again failed to notice the damage on the aircraft; given that the student had done previous preflights properly and I had instructed her that in the case of noticing anything strange; missing or out of place; she should notify me immediately for me to inspect and assess; she failed to notify me of the damage and we proceeded to fly staying in the pattern for 1.1 hours and 9 landings.

Title: A student pilot lost control of the aircraft during landing but the instructor recovered. Both pilots failed to notice wing tip and horizontal stabilizer damage during postflight. His next student also did not see the damage during preflight; but discovered it during that postflight.
