The Standard

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

Assess whether the evidence is relevant and sufficient.

South Dakota English Language Arts Standards (2025)

Teacher's field guide

What Students Need to Do: Students read a claim and the evidence offered for it. They decide which details actually support the claim and whether the evidence is enough to make it convincing.
What Mastery Looks Like: A student can point to a detail that supports the claim and explain the connection. They can also say what evidence is missing when a writer makes a broad claim from one example.
Common Misconceptions: Students may treat any fact about the topic as evidence for the claim. They may also think one strong example proves a claim that uses words like “always” or “most.”
How to Assess It: Give students this claim: “Lunch lines are always long.” Add two details: “One student waited 18 minutes on Tuesday” and “Pizza was served Tuesday.” Ask which detail is relevant and whether the evidence is enough to support “always.”

Lesson moves

Give pairs a cafeteria-line claim, three timed waits, and a menu fact; have them sort the strips and judge whether the waits suffice.
Ask, “Does one student’s 20-minute lunch wait prove the line is always slow? What other wait times would you need?”
Play evidence swap: teams replace a weak detail on a claim card with a stronger fact from a shared evidence pile.
Read a local school board proposal about bus routes; mark which ridership figures support its claim and where more data is needed.
