The Standard

8.RI.8: Delineate (break down) and evaluate the argument and specific claims in a text

Assess whether the reasoning is sound.

South Dakota English Language Arts Standards (2025)

Teacher's field guide

What Students Need to Do: Students read a claim and trace how the author's reasons lead to it. They look for missing steps, weak assumptions, and conclusions that go beyond the evidence.
What Mastery Looks Like: A student can explain where an argument holds together and where its logic breaks. They can name the unsupported leap and suggest a narrower conclusion or evidence that would help.
Common Misconceptions: Students may think a true fact proves any claim placed next to it. They may also accept a conclusion because they agree with it, or treat a survey of five people as proof about everyone.
How to Assess It: Use this exit ticket: 'Four of five students surveyed want a longer lunch, so every student at school wants one.' Ask students to identify the leap and rewrite the conclusion.

Lesson moves

Give pairs printed claim and reason cards about longer lunch; have them connect the cards with string and flag an unsupported link.
Ask partners: 'If five classmates want longer lunch, does that prove everyone does?' Have each student write one sentence explaining their answer.
Play Spot the Leap with three short school policy arguments; teams earn a point for naming the missing step in each.
Show a snack ad claiming 'Nine out of ten students prefer it'; have students list who must have been surveyed before trusting the claim.
