The code for the 2010 Census Block contains information from higher level geographies. For instance, "060599800001002" the GEOID for some hotels/motels near Disneyland also contains information on the state (06 > California) the county (06 > 059 Orange County) the Census Tract (980000) and the Census Block Group within the tract (1). So, having information on Census Blocks you will be able to identify their Census Block Groups (060599800001).
