There are many rules related to pronoun usage in English. I’ve simplified the most common rules into one basic rule with four exceptions and come up with an auction activity to cement these rules into memories. The basic pronoun rule covers 90% of all pronoun usage. Exceptions, in general, drive students crazy. But tell the students that they should be happy there are any rules, since a lot of English usage must simply be memorized. Think about all the irregular verbs and plurals and the diverse ways we write and say words that look or sound similar. To prepare students for the auction or for homework assignments, review sessions, quizzes, or additional pronoun auctions, I’ve included five extra pronoun exercises and answer keys.
