This one can be good fun both for students and teachers with two major skills at play: vocabulary and speaking. I have not attached the key on purpose - I suppose you will enjoy refreshing your knowledge of phrasals (as you see, it's a random selection of them, but I've picked the most 'learnable' ones) . How to conduct the activity without any 'bumps' along the way? Just ask the students to read out each question (or do it yourself), explain the meaning (possibly in English) and then repeat a specific question and expect some concrete answer from a chosen student. :) For this marathon you will need to have the luxury of at least 60 minutes at your disposal, but I think it's worth it!
