Narrative:
I was giving instruction to a student who was flying the GPS approach into cgz runway 5. We were approaching the VOR; which is the approach's final approach fix; at indicated altitude of approximately 4500. I noticed a target on tis (G1000) and or adsb (stratus) which was near the VOR and moving generally from my left to my right at what appeared to show -300 feet. I began looked outside for the aircraft in the area that the tis/adsb suggested. However; I didn't see the aircraft; and I told the student to climb and turn left while I looked for the other aircraft. We climbed to approximately 4800 indicated. The other aircraft asked my altitude and stated he was at 5000 indicated. Then I started looking up; instead of down as I had perceived from tis/adsb; and saw the helicopter at what I visually approximated to be 100 feet above and 500 feet laterally at 0200 o'clock to my position. I was on his right side as he flew past and to the rear of my aircraft at what I estimate to be about a 60 degree angle. After the flight I reflected on the situation; and read the portion of the aim about tis and adsb use; and refreshed my memory that they should not be used for avoidance maneuvering. In the future I will expand my visual search area more quickly; and not maneuver till I have acquired visual contact.

Narrative: I was giving instruction to a student who was flying the GPS approach into CGZ Runway 5.
