Do you need to consolidate object pronouns with short quizzes? Here's a helpful worksheet to revise or assess students' knowledge of object pronouns.
It's a set of three short quizzes, which includes a matching task of noun phrases and the corresponding object pronoun. I advise you to give it groups of three students, and they'll swap each other's quiz to check in the end. It'll be much more challenging to comment whether the answer is correct and more interesting for students to take a teacher role in class time.
