QGIS: Finding and tagging polygons inside a larger polygon

Question

I have two sets of polygons in shapefiles.  One set of polygons is composed of a full and exclusive set of smaller polygons.  But the smaller polygons are not tagged as which larger polygon they were used to build.  Is there a way in QGIS to determine which smaller polygons make up the larger polygons and tag the smaller polygons with the ID of the larger polygon that is belongs to?

I found the correct command in QGIS.  Vector-->Geoprocessing Tools-->Intersection.  Set the larger polygons as the Input Layer and the smaller polygons as the Output Layer.
