Before students can reason about the Convention's problem, they need the raw material: the words, the reasons a convention was called, and the geography of the 13 states. These three activities are fast and front-loaded — the goal is acquisition, not yet analysis.
Introduce and let students sort the unit vocabulary. Sort twice: first by “words about a government's structure” vs. “words about people deciding,” then by student-invented categories (feedback on their reasoning).
| Word | Student-friendly meaning |
|---|---|
| Articles of Confederation | the nation's first plan of government (1781) — a loose league of states with a weak central government |
| constitution | a written plan that sets up a government and the rules it must follow |
| ratify | to formally approve or accept (states had to ratify the Constitution) |
| representation | how a state's people get a voice in government — by population, or one state one vote? |
| federalism | power shared between a national government and the state governments |
| checks & balances | each branch of government can limit the others so none grows too strong |
| separation of powers | splitting government into branches (legislative, executive, judicial) with different jobs |
| compromise | an agreement where each side gives up something to reach a deal both can accept |
| republic | a government where citizens elect representatives to make decisions for them |
| delegate | a person sent to represent a state at the Convention |
| stakeholder | anyone who is affected by a decision or has something at stake |
📚 Background: National Constitution Center · The Constitution, full text ↗ · National Archives · Constitution transcript ↗ — put the vocabulary next to the real document.
Split the class into four expert groups, each studying one topic below, then re-mix into home groups where every topic is represented. Each expert teaches their group. (Jigsaw is one of the highest-leverage surface moves precisely because students must teach.)
Sources for each expert group (free, reputable; confirm access through your district — links open in a new tab):
Under the Articles of Confederation, Congress could not tax, raise a reliable army, or regulate trade between states — and the country slid toward crisis (like Shays's Rebellion).
📄 National Archives · Articles of Confederation ↗
📄 Mount Vernon · Constitutional Convention ↗
Large states backed a plan for a strong national government with representation based on population — the more people, the more votes.
📄 National Archives · The Virginia Plan ↗
📄 DocsTeach · Virginia Plan document ↗
Small states feared being outvoted and backed a plan keeping one vote per state, protecting states that were equal but small.
📄 DocsTeach · New Jersey Plan document ↗
📄 U.S. Senate · The Constitutional Convention ↗
Delegates from states with large enslaved populations argued over whether enslaved people should be counted for representation and taxes — a dispute settled only by hard, and troubling, compromises.
📄 Bill of Rights Institute · The Constitutional Convention ↗
📄 U.S. Senate · “A Great Compromise” ↗
Check for understanding: each home group writes one sentence answering “Give one reason the Articles failed and one reason the states disagreed about representation.”
Give students a map of the 13 states plus a short population table (1790 census is the closest reliable count). Have them shade the states by population and answer: which states had the most people? the fewest? Then connect the data to the dispute: a large state like Virginia wanted votes by population; a small state like Delaware wanted one vote per state. Introduce large-state vs. small-state interests as students see the numbers.
| State (sample) | Relative size in 1787 | Which plan would it favor? |
|---|---|---|
| Virginia | most populous | Virginia Plan (votes by population) |
| Pennsylvania · Massachusetts | large | Virginia Plan |
| Delaware · New Jersey | small | New Jersey Plan (one vote per state) |
Quick write: “A ______ state like ______ favored the ______ Plan because ______.”
