This worksheet can serve as a review of people/jobs and community places for more advanced students or as a mid-unit homework assignment or in-class activity.
Attached to the basic questions on the first page are two pages of "clues" to make the worksheet more interactive. To use these, print out a copy or two of the clue sheets and cut them into strips so that one sentence is on each piece. Give one clue to each student with instructions to keep it secret unless asked. Students can then pair up to ask each other "¿Quién hay?" questions as a structured communicative activity to gather more information, or they can simply call out their questions to the class at large — the person with the clue (or anyone who happens to already know/remember the answer) can help out.
This could also make a good assignment for a (non Spanish speaking) substitute teacher, since students have everything they need to help each other complete the assignment.
