Fences on the Range, 1883 — Who Gets the Land?

A Problem-Based Learning unit. Students step onto the West Texas range in 1883, take on a stakeholder's point of view, and work a real, ill-structured question — building from surface to deep to transfer learning. The teacher is a guide, not the answer key.

Driving question: The year is 1883 in West Texas. For years, cattle roamed the open range freely. Now a new invention — barbed wire — lets people fence off land and water. Ranchers, farmers, small cattlemen, and the railroad all want the land used their way, and fights over fences are breaking out. How should the community and the state settle who can fence the range?

The three-phase path (do them in order)

Problem-solving is a transfer move — it only works once students have knowledge to reason with. So the problem in Phase 3 is deliberately gated behind Phases 1 and 2.

① Surface

Build the knowledge

Vocabulary, a jigsaw read on how the range changed, and Texas regions map work. ~1–2 periods.

② Deep

Connect & organize

Cause–effect concept map, primary sources, points of view, and a structured claim. ~1–2 periods.

③ Transfer

Solve the problem

Meet the problem, take a role, investigate, propose & defend a solution, debrief. ~2–4 periods.

⛔ Gate: don't open the Phase 3 problem until students have finished the surface and deep activities. Meeting the problem too early turns inquiry into guessing.

Big idea & objectives

Big idea: New technology — barbed wire, windmills, and the railroad — and the cattle economy transformed Texas and forced hard choices about land, water, and fairness in a free-enterprise system. The same range looked different to a big rancher, a small cattleman, a farmer, the railroad, and the state.

Know: how the open-range cattle economy worked, how the railroad and barbed wire changed it, and how supply and demand shape a free-enterprise economy.
Understand: the same event looks different from each stakeholder's point of view.
Do: run the problem-solving process end to end — define a problem, gather information, weigh options, choose and defend a solution, and evaluate it (§113.15(c)(22)(B)).

Teacher prep & materials

Print the facilitator guide (teacher moves, map of possibilities, role cards, debrief prompts) and the assessment pack (rubric + individual-in-group).
Chart paper or a projected space for three shared columns: Hunches · Know · Need-to-Know (the KWHL chart).
Vetted sources for investigation (district-approved). Suggested public-domain Texas-history sources are listed in the facilitator guide.
No logins, no accounts — every page runs in the browser. Student writing and products live on paper or in tools your district already vets.

📝 A note on fairness: the fence fights were real and sometimes turned violent. Keep the family and community decision centered on land, water, fairness, and how a shared resource should be used, and handle the conflict briefly and age-appropriately. Guidance is in the facilitator guide.
