Teacher's field guide

What Students Need to Do: Students join two closely related, complete sentences with a semicolon. They also use semicolons to separate list items that already contain commas.
What Mastery Looks Like: A student can write, “The bus was late; therefore, we missed the bell,” with a comma after “therefore.” They can punctuate a list of city and state pairs: “Pierre, South Dakota; Omaha, Nebraska; and Denver, Colorado.”
Common Misconceptions: Students put a semicolon between a complete sentence and a fragment. They may leave out the comma after “however” or use only commas in a list whose items already contain commas.
How to Assess It: Exit ticket: Join “The rain stopped. The field stayed muddy.” with a semicolon and “however.” Then punctuate “We visited Pierre South Dakota Omaha Nebraska and Denver Colorado.”

Lesson moves

Give pairs two sentence strips and a semicolon card; have them join related complete sentences and read the result aloud.
Ask students why “I packed a coat; because it was cold” fails, then have them revise it into two complete clauses.
Run a punctuation relay: teams correct cards with run-ons, misplaced semicolons, missing commas after “however,” and lists of city and state pairs.
Show a school trip itinerary with city and state pairs, then have students punctuate a new three-stop itinerary.
