What This Standard Means
What Students Need to Do
- Students listen to or read two nonfiction books about one subject. They find one way the books match and one way they differ using pictures, facts, or steps.
What Mastery Looks Like
- With teacher questions and page cues, students name an accurate match and difference. They point to a picture, fact, or step in each book as evidence.
Common Misconceptions
- Students may retell each book without making a comparison. They may focus only on cover color or book size instead of pictures, facts, or steps.
How to Assess It
- After reading two short books about frogs, ask, “What is one thing both books show, and what is one thing only one book shows?”

Ways to Teach It
Place two books about penguins beside two hoops, then have children sort copied picture and fact cards into matching and different groups.
Ask, “What did both books teach us about penguins, and what did only one book teach us?”
Show paired pages from two animal books, then students hold up SAME or DIFFERENT cards and explain their choice.
Compare picture directions from two seed packets, noticing which planting steps match and which steps differ.
