What This Standard Means
What Students Need to Do
- Students listen to an informational text and tell what the author thinks. With a teacher’s prompt, they find a detail the author gives to support that opinion.
What Mastery Looks Like
- After a short read-aloud, a student can point to the author’s opinion and a detail that supports it. With a prompt, the student can tell how the detail helps.
Common Misconceptions
- Children may repeat the opinion as the reason instead of finding a supporting detail. They may also give their own reason, even though the author never mentioned it.
How to Assess It
- Read aloud: “Rain boots are great for wet days. They keep your feet dry.” Ask, “What detail tells why the author likes rain boots?”

Ways to Teach It
Give pairs a card reading “Dogs make good pets because they learn tricks” and have them underline the words that tell why.
Read “Our garden is wonderful because butterflies visit it” and ask partners how the butterfly detail supports the author’s opinion.
Play a card match: pair “The playground is fun” with “It has swings” instead of “The gate is blue.”
Show a cafeteria poster reading “Apples make good snacks because they are easy to carry” and ask children to point to the reason.
