Here is a quizlet I made to practice the passive voice: Active and Passive transformations--https://quizlet.com/817139966/active-and-passive-transformations-flash-cards/?i=fo89z&x=1jqt.

It is intended to practice every transformation from active to passive that I could think of, and I used it as a follow-up to my worksheet on all the passive tenses.  In my classes I use this to in the quizlet live mode (the classic live version), and the sentences are all deliberately similar enough to be easily mistaken in order to add to the challenge and hilarity of the game,  (When we play it in class, there's lots of laughing.)  This quizlet could also be assigned to the students as homework for self study.

The idea of doing as many transformations as possible based on the words teacher, student and teach is based on this old find your partner game, which in turn was based on the Headway activity book.

[This is also the second quizlet game I've created on the passive voice.  For the previous quizlet, see: Active and Passive Sentences: Present Simple and Past Simple--https://quizlet.com/_2ec67r, from this post here.]
