What This Standard Means
What Students Need to Do
- Students tell what an author wants readers to know about a topic. They find a detail in the text that helps show the author's point is true.
What Mastery Looks Like
- Given a short nonfiction paragraph, a student names a point the author makes and points to a detail that supports it. The student explains how the detail fits.
Common Misconceptions
- Students may pick an interesting fact that does not support the point. They may give their own reason instead of one the author wrote.
How to Assess It
- Give students this printed exit ticket and read it aloud: 'Rabbits can hide from foxes. Their brown fur blends into dry grass.' Ask them to circle the author's point and underline the supporting detail.

Ways to Teach It
Give pairs 'Ducks stay dry because oil on their feathers keeps water out' and two crayons to mark the point and detail.
After reading the duck card aloud, ask, 'Which words tell how ducks stay dry, and how do they support the author's point?'
Play Point or Proof with cards reading 'Fish need clean water' and 'Dirty water can make fish sick'; students sort the cards.
Post a recess note recommending coats because the forecast says 35°F, then have students underline the detail that supports the advice.
