This is a fun activity that any grade could do (including elementary school 6th or precocious younger grades). I did it as an “introduction to the dictionary” for my JHS 1st graders.
First, I gave them a blanked-out map of the school, and the worksheet. My OTE gave me the map of the school when I originally arrived so I’m not entirely sure where it came from, but someone at your school should have one.
