🧩 CER Argument Skeleton Builder

Students use a graphic organizer to construct their full argument structure: main claim answering which factor most significantly caused the American Revolution, 2–3 sub-claims, at least two pieces of evidence per sub-claim from their evidence logs, and explicit warrants explaining why each piece of evidence proves the point. Students color-code supporting vs. counterevidence and ensure at least one event connects to the collaborative timeline and Revolutionary Map.
