Debate: Prep & Rubric

A DEBATE is a structured argument where two sides take turns making CLAIMS, backing them with EVIDENCE, and answering each other’s COUNTER-ARGUMENTS - all while staying RESPECTFUL. Good debaters do not just talk loud; they prep before debate day. In this Unit 5 celebration lesson you will walk the FIVE prep steps and learn the FOUR-CRITERIA RUBRIC a grown-up will use to score you. Master the rubric first - then practice scoring 3s and 4s on every row.

The 4 rubric criteria you are scored on

The rubric has FOUR rows: CLAIM, EVIDENCE, DELIVERY, and RESPECT. Each row is scored 1 (needs work) to 4 (excellent), so the maximum total is 16. CLAIM means: did you state your side clearly in one sentence? EVIDENCE means: did you back it with at least two facts from reliable sources? DELIVERY means: were you clear and audible - or mumbling? RESPECT means: did you listen to the other side and disagree without insulting? Aim for 3s and 4s on every row, not just the ones you find easy.

1. CLAIM - one sentence that says your side clearly. Vague = 1, sharp = 4.
2. EVIDENCE - 2-3 facts from reliable sources. Cite them by name.
3. DELIVERY - clear voice, eye contact, no rushing. Audible at the back of the room.
4. RESPECT - listen, then reply. Disagree with the IDEA, not the PERSON.

The 5 prep steps before debate day

Strong debaters PREP. Step 1: RESEARCH - read both sides honestly, even the side you disagree with. Step 2: FORM A CLAIM - one clear sentence stating your position ("Outdoor play should be 30 minutes because..."). Step 3: GATHER EVIDENCE - 2-3 facts from reliable sources, each with a citation you can name aloud. Step 4: PREDICT COUNTER-ARGUMENTS - what will the other side say? Write a short rebuttal for each likely point. Step 5: PRACTICE - rehearse aloud at least twice, ideally with a partner who can interrupt you with the counter-arguments you predicted.

1. RESEARCH - read both sides; do not just look for what you want to hear.
2. FORM A CLAIM - one clear sentence; no "maybe" or "kind of."
3. GATHER EVIDENCE - 2-3 facts; each one cited (book, site, expert).
4. PREDICT COUNTER - list 2 counter-arguments you might face; write a rebuttal for each.
5. PRACTICE - rehearse aloud, ideally with a partner playing the other side.

What makes a STRONG claim

A CLAIM is the one sentence everything else supports. A strong claim is SPECIFIC, ARGUABLE, and STATED CLEARLY. Specific means it picks a side - not "outdoor play is interesting," but "outdoor play should be at least 30 minutes per day." Arguable means a reasonable person could disagree - not "water is wet." Stated clearly means no hedging - skip "maybe" and "kind of." Write your claim FIRST, then build the rest of your case to support it. If you cannot say your claim in one sentence, you do not yet know what you believe.

• SPECIFIC - picks a side, names the action, gives a measurable target.
• ARGUABLE - a reasonable person could disagree (not a fact like "water is wet").
• CLEAR - one sentence, no hedging, no "maybe" or "kind of."
• TESTABLE - the rest of your speech can prove or support the claim.

Evidence: which sources count

EVIDENCE wins debates - opinions do not. Strong evidence comes from RELIABLE sources you can name aloud: a published book, a major news site, a museum or government site, a scientist’s study, or an expert interview. WEAK evidence is "my friend said" or "some random blog." The rubric rewards 2-3 cited facts - not five vague claims. Always check: who wrote it? when? does it have an author and date? If you cannot name the source aloud confidently, do not use it.

• STRONG - books, news sites, museum/government sites, expert studies, interviews.
• WEAK - "my friend said," random blogs, social media posts, AI summaries.
• CITE BY NAME - say the source aloud during your speech ("According to NASA in 2024...").
• COUNT - aim for 2-3 strong facts; quality beats quantity.

Predicting and answering counter-arguments

A COUNTER-ARGUMENT is what the OTHER side will say. Strong debaters predict the top two counter-arguments before they walk into the room and prepare a REBUTTAL for each. To rebut, do three things: (1) REPEAT the counter fairly so the listener knows you understood it, (2) ACKNOWLEDGE the part that has merit, (3) EXPLAIN why your side still wins despite that point. Skipping the counter-argument is the fastest way to lose a debate - the audience can SEE you ignored it.

• PREDICT - list the top 2 counter-arguments your opponents will use.
• REPEAT FAIRLY - state the counter the way the other side would.
• ACKNOWLEDGE - admit the part that has merit (it builds trust).
• REBUT - explain why your side still wins despite that point.

Respect: the rubric row most learners lose

RESPECT is one full quarter of your score. Most learners lose points here without realizing it. Respect means: LISTEN before replying (do not interrupt); DISAGREE WITH THE IDEA, not the person ("that argument has a flaw" - never "you’re wrong"); KEEP YOUR VOICE STEADY (no shouting, no sarcasm); and THANK the other side at the end. Even if you crush their argument, a respectful win earns trust from the audience and the judge. Sarcasm and personal attacks always cost points.

• LISTEN - do not interrupt; let the other side finish before you reply.
• IDEA NOT PERSON - "that argument has a flaw" - never "you are stupid."
• STEADY VOICE - no shouting, no sarcasm, no eye-rolling.
• THANK - end with "thank you for the debate" - it costs nothing and earns trust.

Delivery: how you say it matters

DELIVERY is the rubric row about HOW you speak, not WHAT you say. The audience can have the strongest argument in the world and still lose if no one can hear it. Strong delivery means: SPEAK SLOWLY (most nervous speakers rush), KEEP YOUR VOICE AUDIBLE at the back of the room, MAKE EYE CONTACT (do not read the page the whole time), and PAUSE between key points so the audience can absorb them. Practice aloud TWICE before debate day - that single habit raises most learners from a delivery 2 to a delivery 3 or 4.

• SLOW DOWN - nervous speakers rush; pause between key points.
• AUDIBLE - the back of the room must hear every word.
• EYE CONTACT - look up from the page; you trust your prep.
• PRACTICE TWICE - rehearse aloud; mumbling at home becomes mumbling on debate day.
