What Compare and Contrast Means
Compare and contrast is a reading comprehension strategy where students identify what is similar between two or more things (compare) and what is different (contrast). It's one of the foundational comprehension skills that typically emerges around second or third grade, though struggling readers often need explicit instruction well into upper elementary.
Why This Skill Matters for Struggling Readers
Students with dyslexia or reading disabilities frequently struggle with compare and contrast because it requires holding multiple pieces of information in working memory while analyzing relationships. This cognitive load becomes harder when decoding itself is still effortful. The Common Core standards expect students to compare and contrast characters, settings, and events by grade 2, and by grade 3 to compare and contrast key details across texts on the same topic. Without intentional scaffolding, struggling readers fall behind on this skill by mid-year.
Many IEP goals include compare and contrast as a target skill. When included in an Individualized Education Program, the goal typically specifies the complexity level: comparing two characters with visual supports differs significantly from comparing abstract concepts across grade-level texts without aids.
How to Teach Compare and Contrast
Direct instruction works best for this skill. Start with concrete, familiar items before moving to text-based comparisons:
- Use physical objects or pictures students know well (two dogs, two houses) and explicitly state similarities and differences aloud
- Introduce Venn diagrams as a visual organizer, which helps students with spatial organization see overlapping vs. unique attributes
- Use anchor charts with sentence stems: "Both characters are... One character is... The other character is..."
- Pair compare and contrast instruction with explicit phonics review if decoding is blocking comprehension. Orton-Gillingham based programs often integrate this by having students read decodable texts first, then apply comprehension strategies once fluency improves
- Practice with text structures that naturally support comparison, such as paired paragraphs or "alike and different" formats
Building Connections
Compare and contrast overlaps with cause and effect reasoning. Understanding that one character acts differently because of their background is both a comparison skill and causal reasoning. For readers at lower levels, teach one skill at a time. Once compare and contrast is solid, layer in causal reasoning.
Common Questions
- At what reading level should students master this? Guided Reading levels E to J (grades 1-3) typically introduce compare and contrast explicitly. Students reading below grade level need the same skill taught with simpler texts and more visual support.
- What if my child can compare pictures but not text? This often indicates that decoding demand is preventing comprehension. Pair easier decodable texts with compare and contrast practice rather than jumping to grade-level material.
- How does this appear on standardized assessments? Most state reading assessments by grade 2-3 include at least one compare and contrast question, typically worth 1-2 points. Students who skip this skill will miss these items reliably.
