High School Lesson Plan: How to Write a Thesis Statement

written by: Trent Lorcher • edited by: SForsyth • updated: 1/24/2014

Essays without thesis statements are easy to grade: simply write an 'F' at the top of the paper, laugh, and shuffle up the next paper. However, if you're sick of all your students failing, you may need to review this concept with your class.

    The Thesis Statement Dilemma

    On my way out the door, I noticed all the English teachers were busily grading essays. "Hey, Bob," I shouted as I stumbled into his Failing Grade classroom, "Not done with those essays yet? I finished mine an hour ago."

    "How'd you grade them so fast?" he asked.

    "It's simple," I responded, "I didn't teach my students how to write a thesis statement, so grading their essays was easy. I just gave them all F's. While you guys waste your time teaching valuable lessons and then having to actually grade their essays, we watch movies."

    "So, none of your students know anything about writing?"

    "Nope."

    "You're a disgrace!" Bob shouted. He moved toward me, stapler in hand.

    Next thing I remember, I was surrounded by angry tax-payers. Angry tax-payer #1 shouted, "Get up you thief! Our tax dollars pay your salary and you're supposed to teach the children of this great state how to write! I suggest you start doing your job tomorrow morning, or you'll pay dearly!" The angry tax-payer clubbed me with a ruler and knocked me out again. When I awoke, I saw lesson ideas on my desk titled "Writing a Thesis Statement."

    I now share these ideas with you.

    What to Do Before Writing

    Lesson Plan on Writing a Thesis Statement Before writing a thesis statement, the writer must be aware of his or her audience and purpose. Unclear thesis statements emanate from the minds of writers with an unclear purpose. Teach students how to write effective thesis statements by teaching the following:

    • You must begin with a topic question. If your instructor has assigned an essay question to answer, this step has been done for you. If you are doing a research paper, take time to come up with a good topic question.
    • You must form an opinion and state it clearly. Do not be wishy-washy.
    • Be sure you have approached your evidence fairly, without bias.
    • Consider both sides of a controversial issue.
    • Once you've established the topic question, a clear position, and objectivity, you're ready to write a thesis statement.

    What Is a Thesis Statement?

    Students have heard the term thesis statement hundreds of times by the time they reach high school, yet have only a vague understanding of what one is. Your first responsibility is to teach them that a thesis statement:

    • Presents your opinions or thoughts on a subject or an issue. You cannot write an essay without one.
    • Must contain a subject + an opinion.
    • Answers the topic question (the one you created or the one presented to you by the instructor).

    TIP: A thesis statement should never contain the following: in my opinion, I think, I believe, etc. Tell them that the entire thesis represents what they believe. However, it may be helpful for students to begin their thesis statement rough draft with in my opinion, I believe, or I think to make sure they are expressing their thoughts or opinion on a specific subject or issue. When writing the final draft, simply eliminate those phrases.

    Writing a Good Thesis Statement

    It is important to demonstrate the difference between good and bad thesis statements. These instructions will help you teach the latter:

    • A good thesis statement is short and simple: it should be no longer than one sentence, regardless of essay length.
      • Good Example: Success is a result of doing the right things consistently.
      • Bad Example: In a world full of success gurus and books about success, it becomes ever so more important to delineate the one trait that ultimately determines success: doing the right things consistently.
    • A good thesis statement is limited to one main idea.
      • Good example: The key to successful dieting is focusing on a specific goal.
      • Bad example: The key to successful dieting is focusing on a specific goal, which is also the key to successfully running a business and coaching a football team.
    • A good thesis statement is a declarative sentence with no qualifiers (might, maybe, perhaps, etc.):
      • Good example: Lebron James' ability to score, pass, and rebound make him the league's most valuable player.
      • Bad example: Does Lebron James' ability to score, pass, and rebound make him the league's most valuable player?
      • Bad Example: Lebron James' ability to score, pass, and rebound just might make him the league's most valuable player.

    Write It Out

    Knowing what to do and actually doing it are not the same. The following steps will help you and your students write clearly:

    • Write several trial statements: writing is a process. Teach your students to revise their work.
    • If you're having trouble deciding which side to take on a controversial issue, write your thesis statement from two different points of view. Then decide which one better represents your opinion. If you still can't decide, list facts on both sides of the issue and decide which facts make a more persuasive argument.

    Evaluating the Work

    You've spent a lot of valuable classroom time teaching thesis statements, but your lesson is not finished without teaching your students how to evaluate their writing. Instruct students to use the following questions to analyze their statement:

    • Have you answered the question or merely restated it? The following examples are based on this question: Does Romeo's prior feelings for Rosaline diminish the credibility of his love for Juliet?
      • Good example: Romeo's prior feelings for Rosaline diminish the credibility of his love for Juliet.
      • Bad example: This essay examines whether or not Romeo's prior feelings for Rosaline diminishes his love for Juliet.
    • Have you tried to argue both sides of the case? It is important to acknowledge the other side and address the other position. That does not, however, excuse you from choosing a side.
      • Good example: Juliet was not the first woman to capture Romeo's fancy; she was, however, the one who affected him the most.
      • Bad example: Romeo loved Juliet with all his heart, but he loved Rosaline too; It could be argued they were both his favorite.
    • Have you prejudged the issue by using loaded language? Immature writers manipulate readers through emotionally-charged language.
      • Bad example: Immature, whiny, male-pig Romeo, a male harlot, ruined precious Juliet whom he loved no more than Rosaline.

    More Teaching Ideas

    The following activities will help reinforce the concept.

    • Have students create thesis statements on a slice of paper. Collect the paper and read them to the class. Have the class vote on them.
    • Do the same activity, but use individualized white boards to record judgments.
    • Read the thesis statements anonymously. The ones that do not qualify get tossed in the garbage can (visualizing what happens to writing is powerful). Give students a chance to rewrite until they get it right.
    • Write random topics on the board and have groups of students brainstorm good ones.
    • Make the thesis statements part of a writing challenge.
    • Require that students get thesis statements approved before writing an essay.
