Teaching Missouri from the Civil War to Postwar Change and Significant Missourians in Grade 3

Teaching lens: Missouri Civil War • border state • emancipation • postwar transportation and schools • significant Missourians • Grade 3

The final part of a Missouri State History sequence should do more than end the Civil War and jump to a list of famous people. Students need a change-over-time story: Missouri was deeply divided during the war; slavery ended in the state in 1865; transportation, cities, communication, and schooling changed after the war; and individuals contributed to science, literature, music, education, public life, and historical memory.

Three lessons build that closing arc: Missouri in the Civil War, Postwar Missouri, and Significant Missourians.

Teach Missouri as a divided border state

Missouri did not secede from the United States, but that fact does not mean the state was politically or militarily unified. The Missouri State Archives maintains an extensive Civil War records guide documenting state government, military, civilian, constitutional, and school records from the era.

For Grade 3, students can separate four ideas that are often blurred together: Missouri’s formal status in the Union, strong pro-Confederate support among some Missourians, changing military control in different places, and the effects of war on civilians. That framework is more accurate than asking students to label the whole state as simply “Union” or “Confederate.”

Keep emancipation chronology specific to Missouri

The Missouri State Archives timeline records that a state constitutional convention abolished slavery in Missouri on January 11, 1865. The Thirteenth Amendment later ended slavery nationally. This chronology helps students understand why the Emancipation Proclamation did not by itself end slavery everywhere in the United States.

The classroom goal is a clean timeline, not a constitutional-law seminar. Ask: What changed in Missouri? What changed nationally? Which change happened first? Why is it inaccurate to say one document ended slavery everywhere at once?

Move from war to postwar networks

After 1865, avoid a simple “everything improved” story. Railroads expanded, but river transportation did not vanish. Cities grew for multiple reasons. Telephones moved information rather than goods. Public education expanded, but access and quality were unequal.

Postwar Missouri asks students to replace one-cause explanations with a network: transportation, communication, cities, schools, teacher training, and institutions connect to one another. Lincoln Institute also provides an important example of Black veterans and community-building after the Civil War.

Teach progress and unequal access at the same time

Grade 3 students can handle a balanced statement: Missouri built more transportation and educational systems after the Civil War, and those systems did not serve every person equally. That is not a contradiction. It is a useful historical pattern—growth can create new opportunities while old inequalities continue or new ones appear.

End with significant Missourians as an evidence question

The State Historical Society of Missouri offers Grade 3 Historic Missourians lesson resources and a large Historic Missourians collection. The final Missouri lesson uses six people not as a ranking of “the best” Missourians, but as examples of different kinds of contribution.

  • George Washington Carver — science, agriculture, education, and a Missouri childhood near Diamond.
  • Mark Twain (Samuel Clemens) — literature, journalism, and a Missouri childhood that shaped later writing.
  • Scott Joplin — ragtime composition and Missouri connections through Sedalia.
  • Laura Ingalls Wilder — writing and long-term Missouri life at Rocky Ridge Farm.
  • Susan Blow — public kindergarten and educational leadership in St. Louis.
  • Harry S. Truman — Missouri public service and national leadership, studied through documented actions rather than political approval/disapproval.

Ask students what evidence makes a person historically significant. A birthplace alone is not enough; neither is fame. Students can connect a person’s actions to a field, institution, community, or lasting change and then identify which source type could support the claim.

A three-lesson closing sequence

  1. Civil War Missouri: identify formal state status, divided loyalties, military/civilian consequences, Black military service, and emancipation chronology.
  2. Postwar Missouri: trace transportation, cities, communication, education, opportunity, and unequal access as connected changes.
  3. Significant Missourians: test historical-significance claims using evidence from biographies, archives, artifacts, and institutions.

Finish by returning to geography

Ask students to choose one Missouri place or transportation feature that mattered in at least two different lessons. St. Louis, the Missouri River, the Mississippi River, a rail connection, a gateway town, or a regional landscape can work. The explanation should show change over time: the same place can matter for different reasons in colonial trade, migration, war, industry, education, or public memory.
