Homestead Act 1862, Mormon Migration, Women on Overland Trails — Multi-Perspective (Trauma-Informed for Enslaved-People-Brought-West)

Objectives
  • Students identify the Homestead Act 1862 (signed by President Lincoln) and compute quarter-section math (160 acres = 1/4 of 640-acre section).
  • Students identify Mormon migration 1846-1869 as a faith-based migration distinct from gold-seeking.
  • Students examine women's and children's daily-life perspectives on overland trails AND name enslaved peoples brought west on overland trails.

Lesson plan

Warm-up

5 min

Sovereignty Promise + Truth-and-Resilience Promise. Confirm caregiver letter received. Recall: lessons 6-15 named multiple communities affected by westward expansion. Today: 3 more — homesteaders, Mormons, women, AND enslaved peoples brought west.

Teacher moves
  • Recite Promises
  • Confirm opt-outs (light protocol)
  • Set tone for multi-thread lesson

Direct instruction

18 min

Direct teach 3 threads. THREAD A: Homestead Act 1862 signed by President Lincoln. Granted up to 160 acres of federal land (quarter section, 1/4 × 640 acres) to settlers who file claim, live on land 5 years, improve it. About 270 million acres distributed over the Act's life (1862-1976). CRITICAL: this federal land was Indigenous-nation homeland; the Dawes Act 1887 (G5 entry) extended the same idea to allocating tribal lands. Math: a 640-acre section is 1 mile × 1 mile = 1 square mile. A quarter section is 1/2 mile × 1/2 mile = 160 acres. Children compute. THREAD B: Mormon Migration 1846-1869 from Nauvoo IL to Great Basin/Salt Lake Valley UT. Faith-based migration following expulsion from Missouri and Illinois. About 70,000 Mormons made the journey 1846-1869, mostly on Mormon Trail (1,300 miles). Brigham Young led the first group 1847. Mormon migration intersected with Indigenous nations of the Great Basin (Ute, Shoshone, Paiute, Goshute) — named, not erased. THREAD C: Daily life on overland trails — women's and children's labor (cooking, child-care, water-fetching, animal-care), birth and death on the trail, weather. Read Susan Magoffin (1846 Santa Fe Trail) and Catherine Haun (1849 Gold Rush overland) age-adapted excerpts. CRITICAL trauma-informed sub-thread: enslaved African Americans were ALSO brought west by enslaving settlers — including by Cherokee, Choctaw, Muscogee, Chickasaw enslavers on the Trail of Tears (a difficult intersection requiring careful framing — some Indigenous removed nations had adopted plantation-slavery practices from neighboring US states; this is named honestly without monolithic-framing of either group).

Key examples
  • Geography and math meet — the survey-section system structured federal land distribution.
    model 1/4 × 640 = 160 acres. A full section is 1 mile × 1 mile = 1 square mile = 640 acres. A quarter section is 1/2 mile × 1/2 mile = 160 acres. Children draw on section-grid manipulative.
    prompt How many acres in a quarter section?
Checks for understanding
  • What did the Homestead Act grant?
  • How many acres in a quarter section? How is that 1/4 of a full section?
  • What made the Mormon migration distinct from the Gold Rush migration?
Sourcework

Apply MG-7 to Homestead Act 1862: WHO? Congress + Lincoln; WHEN? 1862 (during Civil War); WHY? to settle federal land with citizen claimants; CORROBORATE with Dawes Act 1887 G5 entry (extending allotment to tribal lands); CLOSE READ phrase 'any person... having filed his declaration'; WHOSE voice silent? Indigenous nations on whose land the homesteads were sited.

Section-grid cardstock manipulative: a 640-acre section drawn as 1 mile × 1 mile square divided into 4 quarter-sections (each 1/2 mile × 1/2 mile = 160 acres). Children use markers to identify a quarter section (160 acres), half-quarter (80 acres). Math G4 Spring fraction cross-disc.

Teacher notes

Light trauma-informed protocol for the enslaved-people-brought-west sub-thread including the difficult intersection of some Indigenous removed nations who practiced plantation slavery — name honestly without monolithic framing of either group. Math integration in section-grid is a delightful cross-disc moment children will engage with. Mormon migration is often left out of standard curricula — give it real attention. Note that not all Mormon migration was westward; some Mormons went to Mexico after 1880s anti-polygamy legislation — beyond G4 scope, mention only if children ask.
