I cannot remember where I first came across this resource, but if you or your students are into apocalypse scenarios, then this might be a good resource for you. There are 25 zombie based questions, including worked solutions and pdf handouts of the problems. I am thinking that it might be a good activity for the last few days before winter or spring break, when a portion of my students have already left for vacation. I may even take some of the problems and make an escape game activity.
Access the resource here.
