Incident occurred during pattern ops. Owner in left seat; self in right seat as instructor. On third approach (following two full stop landings) I indicated to student that I would demonstrate a short field approach and landing. On late downwind I assumed control of the aircraft through positive exchange of controls. Short field approach was conducted with verbal instruction. Landing was gear up following failure of gear unsafe warning in flight idle power with full flap. I had mistakenly assumed that Gear had been extended by owner during downwind prior to assuming control; and had not double checked status during final approach under high cockpit workload conditions while giving instruction.
I was flying left seat with my instructor in the right seat. We were practicing short field landings. After my second short field landing; my instructor said he wanted to show me how he flies a short field approach. I flew the departure from Runway XY and retracted the gear on climb out as usual. On the downwind leg; my instructor said 'I have the airplane' and proceeded to set up for his method for a short field landing. Since I was now in a learning mode; I focused primarily on his airspeed; distance from the airport; angle of descent; distance from the runway; etc. He did an excellent job controlling the aircraft and speed and configuring it for a landing within a short distance from the end of the runway. I was calling out his airspeed as it is easier to see from the left side of the cockpit. As he began to flair at the end of the runway; there was a short stall warning chirp as is normal during a flair; but no other warning signals. Then the aircraft slid on the runway and halted on the right side of the asphalt strip. We quickly exited the cockpit after seeing and smelling some smoke. Shortly thereafter; all switches were turned off. There were no injuries. To prevent this incident in the future; insure that the pilot flying (PF) is using the GUMPS process and best for that pilot to repeat each step verbally; don't assume the PF is completing GUMPS mentally and silently. If the non pilot flying does not hear the GUMPS process from the PF; then intervene for assurances even if it is your flight instructor. In addition; there was no gear up warning signal. Test and insure that the system is operable and add a redundant warning system; if possible.
A flight instructor was attempting to demonstrate a short field landing to the pilot owner when he neglected to lower the landing gear; resulting in a gear-up landing.
