When I have a sub, or am doing something that day that requires me to pull students one at a time (such as individual testing or voicing), I have the rest of the class watch a musical/movie with a listening packet. These packets work really well! They help to keep students engaged and focused on the movie, as opposed to talking to each other. I give them a grade for the packet once it is done, and I tell them they are not allowed to talk since this is an "individual assignment".
Included in this zip file are the PDF version of the listening packet, the word document form (for editing), and the answer key. Please do not hesitate to contact me with any questions :)
