Short answer. RI.1.9 asks first graders to spot basic similarities and differences between two books on the same topic. Plain-language help for parents, plus practice.
Quick answer
Take two books about sharks and lay them side by side. What is the same, what is different? That question is RI.1.9. Your child should notice basic similarities and differences between two texts on one topic, in the pictures (photos versus drawings), the descriptions (both mention teeth, only one mentions babies), or even the how-to steps if they are procedure books. Nothing fancy, just honest side-by-side noticing.
Why parents see this skill
Comparing sources is the backbone of real research, and it starts here, with two shark books on the living room floor. Kids also learn something quietly important: books on the same topic are not identical, so one book is never the whole story. That realization is what eventually makes a kid check a second source.
For reference
Identify basic similarities in and differences between two texts on the same topic (e.g., in illustrations, descriptions, or procedures).Official Common Core source
See it, then try it
You do not need a lesson plan. Look for these signs in ordinary play, reading, and conversation, then choose one short activity.
Next library trip, have your child pick a topic and check out 2 books about it. Read one tonight, the other tomorrow. On night two, keep both open and hunt for 2 things that are the same and 2 that are different. The hunt takes about ten minutes once the reading is done.
Lay 2 loops of string (or hula hoops, or drawn circles) overlapping on the floor. Facts only in book 1 go in the left loop, only in book 2 in the right, and facts both books share go in the middle. Write facts on scraps or just place small toys as markers while saying them aloud.
After reading two books on one topic, ask them to pick which one a friend should read, and defend the choice with at least two specific differences. Recommending forces comparison with stakes, and kids take the responsibility hilariously seriously.

Open resourceTwo nonfiction books in one sitting feels like a lot for my first grader. Any shortcuts?
Don't do it in one sitting. Read the books on separate days, then do the comparing as its own short session with both books open for reference. Comparing pages side by side means memory does not have to carry the load. Even comparing just the two covers, or one matching page from each, hits the standard.
What kinds of differences actually count at this level?
Basic ones, and the standard says so explicitly. Different pictures, different facts included, different order, one book funnier, one more detailed. A child who says "both tell how bees make honey, but only the yellow book shows the hive inside" is meeting the standard completely. Deeper analysis of author choices comes years later.
