I was flying with my Private Pilot Student working on maneuvers. I noticed at first my flaps weren't responding normally. Next my comm 1 radio had a lot of static when I tried to communicate. I then switched to comm 2 and did a radio check. Someone responded and said 'loud and clear'. Moments later my transponder failed. I called up ZZZ Tower and was requesting to come in for landing. Once the Tower began to respond; comm 2 failed. I called ZZZ Tower via my phone and received a landing clearance. I landed safely and was escorted to the ramp.
Flight Instructor conducting training reported radio failure; transponder failure; and malfunctioning flaps.
