What SL.8.3 Means in Plain English
Eighth graders hear a speech and map it: the claim, each reason, the evidence under each. They judge whether the reasons lead to the claim and the evidence is enough. New this year: catching evidence that sounds impressive but has nothing to do with the claim.
Seventh graders (SL.7.3) outline a speaker’s claims and judge the reasoning and evidence. Eighth grade adds one sentence students should be able to say: “That’s true, but it isn’t about the claim.” In grades 9 and 10 (SL.9-10.3), students also weigh rhetoric and name fallacies and distorted evidence.
SL.8.3 I Can Statements
- I can map a speaker’s claim, reasons and evidence while I listen.
- I can judge whether the evidence is enough to prove the claim.
- I can point out evidence that has nothing to do with the claim.
SL.8.3 Worked Example
A classmate’s one-minute speech and two evaluations of it. One grades the delivery; the other tests the argument.
Listen to Jordan’s speech, then evaluate his argument. Jordan: “Our school should switch to a four-day week. One district in another state switched and saw attendance go up. Teachers would get Fridays to plan lessons. My cousin’s school has a four-day week, and he loves it. And our cafeteria throws away tons of food every day.”
Common Mistakes with SL.8.3
Grading the delivery, not the argument
“She made eye contact and sounded confident, so her argument was strong.”
Try this: Split the feedback sheet into Delivery and Argument columns, and for this practice, fill in only the Argument column.
Judging the claim instead of the support
“His argument is good because I want a four-day week too.”
Try this: Have students evaluate a speech arguing the side they disagree with, then one arguing their own side, using the same checklist.
Letting the off-topic fact slide
Nobody objects when a speech for a longer lunch adds that the gym floor is scratched
Try this: Read aloud a short argument with one irrelevant fact planted in it, and have students stand when they hear it.

Quick Check
- What claim does Jordan make, and what are his two reasons?
- Which piece of evidence in Jordan’s speech is irrelevant, and why?
- Why is the attendance evidence relevant but not sufficient?
