Who Did It?

This worksheet helps students in Grades 4, 5, and 6 strengthen grammar accuracy, sentence construction, and understanding of agency in writing by focusing on the preposition by. Students read sentences that include an action and the performer listed in parentheses, then rewrite each sentence using by to clearly show who completed the action. The activity connects grammar rules to clear communication and well-formed sentence structure.
