Then I use a tennis ball and groups of 6 for hot potato. One person calls out a phrasal verb, a permutation of the four catagories, and tosses the ball to someone. The person who catches it has to conjugate the verb CORRECTLY IN A SENTENCE. It becomes very interesting since not all possible combinations of person/number/tense/form are actually used in real English, but as long as the student can convey that s/he knows the meaning it is acceptable. It is good practice with knowing where to put prepositions in sentences with phrasal verbs. For example, if a student is given 1st person singular past perfect continuous of the verb wake up, both "I had been waking up every morning at 7 am" and "I had been waking him up every morning at 7 am" is acceptable. The student who finished the sentence then chooses the next victim, or, as i would say from my old college French teacher, "voluntaire ou victim?"
Variations include multiple groups competing to complete as many sentences as possible in 15 minutes, or students competing individually to finish as quickly as possible. The teacher's role is to float between groups, answer questions about possible sentences and follow the score keeping, if necessary.
