Supporting Claims with Evidence

Overview

In this second lesson of the "Mastering Argumentative Writing" unit, students analyze how effective writers support their claims with relevant evidence. Students practice selecting and integrating evidence from provided texts to strengthen argumentative writing.

Learning Intentions

• Students will be able to identify and evaluate the relationship between a claim and its supporting evidence.
• Students will be able to distinguish between strong and weak evidence in argumentative writing.
• Students will be able to write a clear claim supported by relevant textual evidence.

Success Criteria

• I can explain why a piece of evidence does or does not support a given claim.
• I can select relevant evidence from a provided text to support my own claim.
• I can write a claim-evidence statement that is logically connected and persuasive.
• I can support my claims with relevant evidence.

Curriculum Links

Lesson Structure (60 minutes)

0–8 min — Warm-Up: Claim or No Claim? Display three sentences on the board — one fact, one opinion, and one arguable claim. Ask students to identify which is a strong argumentative claim and briefly discuss why. This activates prior knowledge from Lesson 1 and focuses students on the distinction between claims and general statements.

8–20 min — Mini-Lesson: What Makes Evidence Effective? Using a short, age-appropriate model paragraph (pre-selected from a provided text on a relevant topic such as social media's impact on teenagers), walk students through the structure: claim → evidence → explanation. Highlight examples of strong evidence (specific, sourced, relevant) versus weak evidence (vague, off-topic, anecdotal). With only five students, invite real-time questioning and discussion to make this interactive rather than lecture-based.

20–32 min — Guided Analysis: Evaluate the Evidence Distribute a two-column worksheet featuring three pairs of claims and evidence snippets. Students work in pairs (or as a group of three for one pair) to rate each evidence snippet as "strong," "weak," or "irrelevant," writing a one-sentence justification for each rating. Circulate to prompt thinking: "Does this evidence directly prove the claim?" Bring the group together for a brief share-out at the end of this segment.

32–48 min — Independent Practice: Write Your Own Claim-Evidence Statement Each student receives a short provided informational text (approximately one page). Students independently write one clear argumentative claim and select at least one piece of evidence from the text to support it, then write an explanation connecting the two. Students using the graphic organizer fill in the Claim, Evidence, and Connection boxes before drafting sentences. Read-aloud audio is available for students who need it.

48–56 min — Peer Share and Feedback Students read their claim-evidence statements aloud to the group (small class size makes this manageable and low-stakes). Peers use a simple sentence frame — "Your evidence is effective because… / You could strengthen it by…" — to give one piece of positive feedback and one suggestion. The teacher facilitates and models constructive academic language.

56–60 min — Wrap-Up and Exit Ticket Students write a one-sentence response on a sticky note or index card: "One thing that makes evidence strong is…" Collect as an informal formative check. Preview Lesson 3: students will learn how to integrate counterarguments into their writing.

Resources

• Pre-selected informational text on a relevant, age-appropriate topic (e.g., social media and teenagers, climate responsibility, or school policy)
• Model argumentative paragraph for mini-lesson (teacher-prepared)
• Two-column claim-and-evidence analysis worksheet
• Graphic organizer: Claim / Evidence / Connection (for students who need support)
• Sentence frames for peer feedback
• Sticky notes or index cards for exit tickets
• Whiteboard or projected display for warm-up sentences
• Audio recording or read-aloud version of the provided text (for dyslexia-friendly access)

Assessment

• Formative: observation during guided analysis and circulating during independent practice to check understanding of the claim-evidence relationship.
• Formative: peer feedback conversation as evidence of students' ability to evaluate argumentative writing critically.
• Exit ticket: one-sentence written reflection collected to inform planning for Lesson 3 and identify students who need re-teaching.

Differentiation

• Support: Provide the graphic organizer (Claim / Evidence / Connection) to scaffold the independent writing task; pre-highlight sections of the informational text where strong evidence is likely to be found so students are not overwhelmed by searching the full text.

• Dyslexia-Friendly Option: Offer an audio read-aloud or audiobook version of the provided informational text so students can access content without decoding barriers; allow verbal responses during independent practice if written output is a barrier.

• EAL/SEN: Pre-teach key vocabulary (claim, evidence, relevant, justify) using brief visual examples before the mini-lesson; allow sentence starters for the written task ("My claim is… / This is supported by… / This connects because…").

• Extension: Encourage advanced learners to locate an additional piece of evidence from a self-selected academic or credible source to further support their claim, and to write a second sentence explaining why that source is trustworthy. This builds source evaluation skills ahead of more complex argumentative writing.
