Aircraft; Procedure
Private pilot student working toward a commercial certificate; practicing a simulated engine out within 1 mile of the runway from 2;200 AGL. The student was guiding the aircraft toward the runway. We had passed the threshold and were still high. I (the instructor) was directing coordinated S turns in order to not overshoot the available runway. We were using Runway X with winds approximately 330 at 7kts. On the last turn back toward the runway we were just west of the runway and I then noticed that airspeed was getting too low; we attempted to still land the plane; at this point only about 20ft above ground. We continued the descent and were touching down on the runway but not aligned with the runway. The student initiated a bank to realign the aircraft with the runway and the left wing apparently scraped the runway without any indication on the flight controls. I took the controls and leveled the wings; controlling the aircraft through a bounce. We departed the runway at an angle into the grass median between the runway and taxiway A. We continued the ground roll in the grass; crossing taxiway G before coming to a stop.  Upon shutting down and inspecting the aircraft we found the scrape on the left wingtip and corner of the left aileron.
Instructor Pilot reported a wing tip impacted the ground during training and the aircraft departed the runway during landing.
