Narrative:

My student and I were doing a soft field takeoff. My student was on the controls and took off with a very high pitch up attitude to get the nose off the ground. He didn't think the airplane had lifted from the ground and continued to pull back on the yoke; causing for the plane to be very unstable on takeoff and in turn not getting into ground effect and positive energy. I took control and brought the nose down; but we had already shifted right of the runway due to a high crosswind and the wings were rocking side to side. I think it was also due to us having a passenger onboard and my student not being aware of the cg shift and more weight that was added by us having full tanks. We did not realize that we had hit the right wing tip until post flight. We also noticed the tail skid plate had been dragged from the result of the high pitch attitude. We flew the plane [multiple legs] not knowing there was any damage done to the plane.corrective actions to this situation would be to keep the nose just slightly above the ground and still being able to see the runway. Keeping an eye on airspeed on takeoff; especially on soft field takeoffs because of that low airspeed on liftoff. And the inaction to turn back and have maintenance check out the plane before continuing.
