I was on the ground at JNX with my student pilot getting ready for a soft field takeoff. The pattern was very congested with 5 aircraft in the pattern in various places. An aircraft had just landed; and there were a few other aircraft on downwind. A downwind aircraft stated that they were extending their downwind for departing traffic. I told my student that after the landing aircraft had exited the runway to be ready for immediate departure. The exiting aircraft called clear at this point and I told my student to make the radio call and take us out. As we were taxing out the aircraft that had said they were extending downwind was now on a 1.5 mile final. I told the student to accelerate and a radio call over the CTAF said go-around. I took the controls from my student to avoid a confliction with the aircraft going around. The aircraft going around side stepped to the right to avoid conflict. At no time was a G1000 traffic advisory issued; and no aircraft came close to contact. The overpopulated pattern with 4 aircraft doing stop and goes and my aircraft trying to find a spot to get out was a contributing factor to this issue. After the aircraft sidestepped; they immediately departed the pattern; and we continued our takeoff and entered left closed traffic to continue landing practice.
Myself and a student who is currently working toward his CFI certificate went out for a training flight. After an hour of practicing maneuvers we approached JNX to practice takeoffs and landings. During our final approach into landing on Runway 21 at JNX my student made a call to let the other traffic in the pattern know of our position and our intentions; shortly after this call another plane pulled out on to the runway in frontof us. We made the decision to go-around and commenced a turn to the west so not to be on a collision course with the downwind traffic. We then proceeded to climb and leave the area.
GA instructors on different aircraft reported conflicting with each other at JNX non-towered airport.  Reportedly; one of the instructor's aircraft took the runway for takeoff as the other was on final prompting a go-around and sidestep to avoid a possible collision.  Traffic volume at the uncontrolled airfield was cited as a contributing factor.
