Narrative:

During routine training; takeoffs and lndgs on runway 28L at ZZZ; we were practicing a no flap landing. I was explaining the site picture; nose high attitude with flaps up; and missed the before landing check light. The gear had not been extended. During the landing flare; tower notified us 'gear up.' I took control of aircraft; executed a go around; during which propellers struck runway. We knew something hit but had no other indication if propeller damage. Tower cleared us for a tear drop approach back to runway 10R at fcm. We returned with no other problem. Supplemental information from acn 717511: I was concerned about the wide traffic pattern and forgot to call for gear down and gear landing check.
