Narrative:

I was on an instructional flight with my student. We were level; headed southbound in slow flight; when I saw a flash that looked like a strobe light. This caught my attention because our aircraft does not have strobe lights. When I started to look; this is when the passing aircraft overflew us from the 3 o'clock to the 9 o'clock (west to east). By the time the aircraft was overhead/past us; there was no evasive action that could have been taken. At the time I was not talking to flight following or lakeland tower.
