Three sentences need fixing on this set: "My teacher Mrs. Lopez gave us extra recess time" needs commas around the appositive, the zoo-aquarium-museum field trip line is missing series commas, and "Our dog Buster a golden retriever" needs commas hugging that appositive on both sides.
Fill-in items cover the Oxford comma, the meaning of an appositive (a noun that renames another), and where to place commas when an appositive sits in the middle of a sentence. Short-answer prompts ask students to write their own appositive sentence and explain why series commas matter for reader clarity. Strong starter practice for two of the most-used comma rules in fifth-grade writing.
