This letter uses the six typical comma rules. After teaching a lesson on these rules, I have students complete this comma hunt. They've loved arguing over where a comma should go. Have them fold the bottom backwards, hiding it until they've finished.
This sheet uses these rules:
2) When you are introducing someone
3) interrupting a thought
4) Speaker tags.
5) Double Adjectives
EX: She avoided a terrible, sticky fall.
6) FANBOYS. Use a comma when you are using coordinating conjunctions
See my comma note sheet, if you'd like to have that resource as well!
