Narrative:

My student and I were in the right traffic pattern for runway 23. We called right abeam for touch and go. The controller told us that we were number 3. We found our traffic and told him; 'traffic insight; will follow; number 3.' at the time of this transmission we were abeam. Number 1 was on short final for 23 (just before the approach lights for 23). Number 2 was about a 1.25 mile final for 23 (just outside the river.) we had the traffic insight the whole time. We waited until the number 2 traffic was abeam us in the opposite direction and turned base (we turned base just before the river and just past the railroad tracks. About 0.8 mile from the runway.) we continued and turned final. After we turned final we heard the skywatch go off; 'traffic;traffic'. The traffic was + 400; right above us. Immediately we heard over the radio; [aircraft Y] has traffic on final in sight. (I think he might have said he was avoiding us; but I'm not sure exactly how he said it.) the controller said; '[aircraft X]; (us) looks like you cut someone off.' I quickly apologized over the radio and said; 'sorry just before we landed I saw 2 of our training planes taxiing back to the ramp on charlie. We got blamed for the near midair collision; but I'm not sure it was entirely my fault. I talked to [the pilot of aircraft Y] on the ground 20 minutes later. He said he didn't have a number in traffic to follow; but he was on an extended left downwind and was told to keep following traffic. I'm not sure if it was his fault or my own.
