Claim, Evidence, Reason: The Building Blocks of a Winning Argument
Your class is arguing about a real question: should recess be 30 minutes instead of 20? Some classmates blurt out "yes!" the second they hear it. But a strong debater doesn't just say yes or no — they build an argument out of three parts: a claim, evidence, and reasoning. Master those three parts and your ideas become almost impossible to brush aside.
What You'll Learn
How to state a clear claim instead of just an opinion. How to tell strong evidence (facts, data, examples) apart from weak evidence (guesses, feelings). How to connect evidence to your claim with reasoning. How to build a respectful rebuttal to someone else's argument.
The Three Building Blocks
A CLAIM is the main point you're arguing for — for example, "Our class should get 30 minutes of recess instead of 20." EVIDENCE is the proof that backs up your claim — facts, statistics, expert quotes, or real examples. For example: "A study from the CDC found that longer recess breaks are linked to better classroom focus and less fidgeting in elementary students." REASONING is the sentence that connects your evidence to your claim and explains WHY the evidence matters. For example: "Since longer breaks improve focus, giving our class 10 more minutes of recess would likely help us pay attention better during math and reading time."
Evidence has to be something you could check and confirm — a number, a study, a documented example. "Recess is more fun than math" is an opinion, not evidence, because it can't be proven true or false.
Listening for the Other Side: Rebuttals
A rebuttal is a response that shows why the other side's point doesn't hold up, without attacking the person. Suppose a classmate argues, "Longer recess means less time for math, so our test scores will drop." A strong rebuttal uses evidence too: "Research on recess actually shows the opposite — students who get more active break time tend to concentrate better once they're back in class, which can help scores instead of hurting them." Notice the rebuttal doesn't say "you're wrong" — it addresses the IDEA with new evidence.
Debate Etiquette: Disagree Without Being Disagreeable
Good debaters follow a few simple rules: wait for your turn instead of interrupting, use a calm and steady voice even when you disagree strongly, and always respond to the IDEA, not the person — saying "I see it differently because..." works much better than "That's a dumb idea." These habits keep a debate focused on finding the best answer instead of turning into an argument between people.

Build and Share a Mini-Argument
Pick a real question your class could actually debate (recess length, homework amount, classroom pet, or another topic your teacher allows). Write exactly three sentences: one CLAIM, one piece of EVIDENCE, and one REASONING sentence connecting them. Read your mini-argument to a partner. Have your partner respond with one respectful rebuttal sentence that addresses your idea, not you.
