Students can go take interactive pronoun quizzes online and score points for correct answers. Depending on the quiz that your student chooses, he can have a running score on the screen to motivate him — each time he chooses the correct pronoun for a sentence, his point total will increase. Offer your students prizes for perfect scores or personal bests.
Using either photocopied text or an online interactive game, you can have students scan existing text and identify singular and plural pronouns. Separating pronouns from other parts of speech can confuse elementary (and even middle) school students, so add to the fun by giving stickers, candy or other small prizes for each successful "find."
This sort of activity offers students a text with blanks where the various singular and plural pronouns should be. Post the correct answers at various places throughout the room, and divide your class into pairs or small teams. The team with the first correctly filled page is the winner.
Most "Mad Libs" puzzles do not use pronouns, for the simple reason that it's hard to interject a vivid pronoun into a sentence; instead, they use nouns, adjectives, adverbs and verbs. Add some learning to the fun by deleting some pronouns from the puzzle you intend to read and asking students for a "Singular Personal Pronoun" or a "Plural Intensive Pronoun" in between wacky adjectives.
