Narrative:

I was training a student out of ZZZ; which happens to be a parachute drop airport as well. After training; about 40 minutes doing landings; the drop plane began to make a descent.I was making calls for every phase of the traffic pattern (crosswind; downwind; etc.) when I get an alert for traffic. I look out to my right when I see the drop plane on a collision course with my student and myself (we are abeam the numbers on downwind). I make a call on the radio informing the pilot that the correct entry is midfield downwind and that he is less than 300 ft. From colliding with my aircraft. The jump plane spiraled down from 5000 ft.+ MSL to 1600 ft. MSL in a matter of a couple minutes and tried to enter a short base for the runway. If the plane entered the pattern at midfield downwind; this could've been avoided.
