written by: Trent Lorcher • edited by: SForsyth • updated: 1/17/2012

Use semicolons to improve sentence structure; use them to look smarter. This lesson plan will help you to teach your students about the value of semicolons and when to use them.

    A Strange Dream

    I had mastered teaching Greek and Latin Roots. I had created some of the best Romeo and Juliet lesson plans ever. I had taught students how to use commas. I felt good. Then I read their essays and realized they had no idea when to use a semicolon. I failed to teach them semicolon rules. I needed to punish myself, so I strapped a 12-volt battery to my eyelids, connected it to a car and awaited the pain. The shock knocked me out. When I awoke, there stood a giant, bearded semicolon, explaining to me how to explain semicolon rules. He then whacked me on the head with a stapler and knocked me out again.

    When I awoke, a "when to use semicolons" lesson plan rested on my desk. Unfortunately, it was the principal's car battery I had connected to my eyelids and he fired me the next morning. I never got to use my lesson plan.

    But you can.

    When to Use Semicolons

    Use semicolons in the following ways:

    • separate items in a series if any of the items contains a comma.
      • Sharks love to eat shrimp, whales, and surfers; swim in the open ocean; and star in movies depicting blood, gore, and parades down main street.
    • to separate independent clauses joined by a conjunction if either of the independent clauses contains a comma.
      • I got lost outside of Denver last year; I got yelled at by my wife, laughed at by my son, and beat up by the paper boy.
    • to join two related independent clauses if no conjunction is used.
      • Some invest in a 401 (k); others invest in a Roth IRA.
    • before a conjunctive adverb (however, therefore, hence, consequently), or a parenthetical expression, that joins the clauses of a compound sentence.
      • No one with common sense would actually cascade; therefore, a more correct description would be canyoning with only a rope used to hang yourself after you plummet thirty feet and lie in pain with a broken back on the canyon floor with no hope of rescue.

    Prepare large strips of paper with the following:

    • 8 semicolons, 6 periods, 8 commas, 2 and, 1 however.
    • Write the following model sentences or come up with ones of your own. It's best to use sentences from literary works you've taught or sentences about topics of interest.

      • Farm animals are adored by children
      • young ones look to them for comfort and love
      • Farm animals possess power and influence
      • they abuse this trust by breaking fences and tearing up lawns
      • Disobedient animals include pigs
      • sloppy critters who stink up the yard
      • sheep
      • incessant blabbers
      • bulls
      • fierce rib breakers

    • Discuss semicolon rules.
    • Instruct students to copy the rules in their notebook.
    • Hand out the sentence strips.
    • Instruct the possessors of two complete sentences to place them on the board side by side.
    • Discuss when to use a semicolon and instruct the student with a semicolon to place it in the appropriate spot.
    • Remove the two sentences and continue with the other semicolon rules, asking individual students to place their sentence, word, or punctuation in the appropriate spot.
    • The final result should look like this:
      • Farm animals are adored by children; young ones look to them for comfort and love. Farm animals possess power and influence; however, they abuse this trust by breaking fences and tearing up lawns. Disobedient animals include pigs, sloppy critters who stink up the yard; sheep, incessant blabbers; and bulls, fierce rib breakers.
