Narrative:

Four aircraft were flying in the pattern for runway 05 and one aircraft was shooting ILS (instrument landing system) practice approaches on runway 23. A sixth aircraft reported he was 7 miles out for runway 23; but then did not make another radio call. As we were on runway 05 the practice ILS traffic went missed for runway 23; so we continued with our touch and go. When we reached around 500 feet; I looked out and noticed an aircraft at the same altitude on a collision course with us. I took the flight controls from my student and quickly banked hard into the left crosswind. We missed each other by roughly 500 feet horizontally. The other aircraft did not acknowledge there was any issue and continued to land 23 even with other aircraft already established in the pattern on short final for runway 5.I realize that in this case we were on a head on collision hazard and I should have turned the aircraft to the right instead of left; but chose to go right to maintain in the traffic pattern.
