Narrative:

I was instructing a student in VFR conditions. We had been cleared for touch and go on runway xxl at ZZZ. My student was preparing for landing on runway xxl. At approximately 600 feet AGL; I identified traffic in the downwind leg with landing lights flashing. At the time I identified the traffic; I recognized that traffic starting to turn its base leg in front of us and on a direct path to our aircraft at the same altitude. I immediately notified the tower of the traffic turning toward us. At that time I called for an immediate go around and my student initiated full power and a climb. At the same time the tower called a turn for the other aircraft away from us. I then notified the tower that we were going around. We continued our climb to 6;700 feet and entered a crosswind turn at approximately the approach end of runway xxl per the instruction of the tower. I estimate that the other aircraft was within 500 feet of us at the same altitude. We then continued our flight with no additional issues.
