This isn’t a lesson on how to use apostrophes, but a review activity once students have already been introduced to this concept.
I wrote out sentences without apostrophes on sentence strips and had students add macaroni to show where the apostrophes should be. On the answer sheet, students label whether they added the apostrophe to a contraction, singular possessive, or plural possessive.
I've left this as a word document, so feel free to modify for your own needs.
