What This Standard Means

What Students Need to Do

Students read two informational texts about the same topic. They identify each text’s main points and key details, then explain what is alike and different.

What Mastery Looks Like

Students identify the main point and key details in each text. They explain what the texts share and how they differ, using accurate evidence from both.

Common Misconceptions

Students may list facts from each text without making a comparison. They may focus on length, pictures, or small details instead of main points. They may also treat different details as contradictions.

How to Assess It

Give students two short passages about how bats find food. Ask them to write one shared main point, one different detail, and evidence from both passages.

Ways to Teach It

  1. Give pairs fact cards from two short volcano texts; students place them in labeled hoops for shared, Text A, or Text B.

  2. Ask, “Which text gives the stronger explanation of animal camouflage, and which key detail supports your answer?”

  3. Play Comparison Relay: teams read two weather passages and race to match main-point cards with supporting details from each source.

  4. Compare two school lunch menus and their nutrition notes, then decide which menu better meets a student athlete’s needs.
