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 with a listening packet. This is the first one I made, and it worked really well! It helps keep student 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".
Make sure not to print the answer key with your packets! If you would like the word document form of this packet, don't hesitate to contact me :)
