Evaluating Evidence: Relevant or Just Filler?

Students learn that not all evidence actually supports a claim — and practice telling relevant, sufficient evidence from irrelevant details that only look convincing, a key skill for thinking critically.

Learning Objectives

Students will be able to…

  • ✓Judge whether evidence is relevant.
  • ✓Spot irrelevant evidence.

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
What makes a piece of evidence relevant?
It is directly connected to the claim and actually helps support it.
QUESTION 2
Why can an argument be weak even if it has lots of facts?
Because the facts may be irrelevant (off-topic) or insufficient — impressive-sounding but not actually supporting the claim.
QUESTION 3
For the claim “we should recycle more,” is “recycling reduces landfill waste” relevant or irrelevant?
Relevant — it directly supports the claim.

Going deeper? Strengthen the argument.

Have students take a claim with weak evidence and replace irrelevant filler with strong, relevant evidence. A printable argument-strengthening sheet is in the ELA library.
