Do you need to consolidate object pronouns with short quizzes? Here's a nice worksheet to revise or assess students' knowledge on 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.
This PDF worksheet also includes an answer key page and a QR code key for you to give it as a homework assignment. Have a look at the questions here.
