Missouri State History | Louisiana Purchase and Lewis & Clark RT Script & Mini Readers | Grades 3-5

Bring Missouri State History to life with a Grade 3-focused Reader’s Theater script and two differentiated Mini Readers for grades 3–5. A museum trunk full of flags, instructions, route clues, and expedition records helps students replace an empty-land myth with a fuller Louisiana Purchase and Lewis and Clark story.

Mia, Leo, and Sam investigate a museum trunk whose first label reduces the story to an empty-land purchase and a two-person adventure. Three flags lead them through the Spain-to-France-to-United States transfer at St. Louis. Instructions reveal that Jefferson’s mission combined commerce, route finding, mapping, science, diplomacy, and information gathering. Camp Dubois, St. Louis, and St. Charles show how Missouri’s river corridor supplied people, knowledge, and skills. The students widen the Corps beyond Lewis and Clark, examine York’s contribution alongside his enslavement, correct the whole-route Sacagawea myth, compare goals with results, and finish with a more evidence-based museum caption.
