Compare two nonfiction books on the same topic, naming at least one way they are alike and one way they are different.
Two different books can be about the exact same topic, like two books about frogs, but tell it in different ways: different facts, different photos, even a different order.
Comparing books helps you notice what each author thought was most important, and often teaches you more than either book alone.
Mastery looks like: They compare two nonfiction books on the same topic, naming a shared fact and a unique fact from each.
Common stumbles: Only summarizing one book instead of actually comparing facts across both.
