Student and instructor were practicing landings.  We came in for a full stop on the main runway. Approach was stable with a slight crosswind. Upon touching down the crosswind blew us to the left side of runway. To correct student used rudder to come back to centerline and slightly over corrected. We clipped our right wing and light on the runway/taxiway sign. After noticing we were out of control the instructor took controls and corrected to get back on the runway.
Flight Instructor reported the student lost control of the aircraft landing in a crosswind and the aircraft's wing clipped a taxiway sign.
