Grade 4 Spring — US National Geography and Westward Expansion (1803–1890): Whose Land, Whose Story, Whose Future?

Lesson 5 50 min hist.g4.s.lesson_05

Westward Expansion Chronology Strip — 1803 to 1890 with Three Parallel Bands

Skills targeted

Construct a 1803–1890 westward-expansion chronology with parallel bands showing continuous Indigenous presence and enslaved-people-brought-west events

Objectives

Students place 12 event cards in chronological order on MG-4 chronology strip.
Students identify the THREE parallel bands (event band; continuous-Indigenous-presence band; enslaved-people-brought-west band).
Students explain why parallel bands matter for honest history.

Lesson plan

Warm-up

5 min

Quick recall: name two Westward Expansion events. Predict their year.

Teacher moves

Affirm thinking
Surface uncertainty about dates — that's why we have chronology strips

Direct instruction

12 min

Direct teach MG-4 chronology strip from 1803 to 1890. Show 3 PARALLEL BANDS: middle band is event timeline; UPPER band is continuous Indigenous presence (with 'time immemorial' arrow extending off the left edge — Indigenous nations have been here continuously since before this strip begins); LOWER band is enslaved-people-brought-west events (Missouri Compromise 1820, Fugitive Slave Act 1850, Dred Scott 1857 — G5 entry markers). Place 12 event cards in order on strip.

Key examples

Honest history uses parallel bands — we don't tell only one story.

model The upper band is continuous Indigenous presence — Indigenous nations have been here since time immemorial, all through 1803-1890, and continue today. The events on the middle band happen ON Indigenous-nation land.

prompt What is on the UPPER band, above the year marks?

Checks for understanding

Did the Trail of Tears or the Gold Rush happen first?
Why is the upper band labeled 'time immemorial'?

Sourcework

MG-4 chronology strip is itself a curated source — the choice of which events to highlight is a historian's choice. Children critique: 'what events are NOT on this strip?' (e.g., Indigenous-nation events that happened independently of US legislation)

Chart

MG-4 mounted at child eye level, 12 feet long, 24 inches tall. Three colored bands: upper band orange (continuous Indigenous presence), middle band white (event timeline), lower band yellow (enslaved-people-brought-west events). 'Time immemorial' arrow extends off left edge of upper band.

Chart

Westward Expansion Chronology Strip — wall-length (12-foot) horizontal strip showing 1803–1890 with year-tick labels every 5 years and event annotations at: 1803 Louisiana Purchase, 1804–1806 Lewis and Clark expedition, 1830 Indian Removal Act, 1830s–1850s Trail of Tears multiple removals (5 separate sub-bands shown), 1836 Texas Revolution, 1846–1848 Mexican-American War, 1848 Treaty of Guadalupe Hidalgo, 1848 Sutter's Mill gold discovery, 1849 Gold Rush peak migration, 1862 Homestead Act, 1862 Pacific Railway Act, 1863–1869 Transcontinental Railroad construction, 1869 Promontory Summit golden-spike ceremony, 1875 Page Act, 1882 Chinese Exclusion Act, 1887 Dawes Act (allotment — G5 entry). A second parallel band BELOW the year band shows the CONTINUOUS PRESENCE of Indigenous nations across the entire 1803–1890 period (and before, and after, to present-day) — labeled 'Indigenous nations have been here continuously since time immemorial — they ARE here today'. A third parallel band ABOVE shows enslaved-people-brought-west events (1820 Missouri Compromise, 1850 Fugitive Slave Act, 1857 Dred Scott decision — G5 entry markers). Style: timeline with three parallel bands, color-coded for thread continuity.

Tasks

In pairs, place 12 event cards on MG-4 in chronological order.

scaffold Use the year on the card; check with partner; check with teacher before final placement.
For each event card, draw one ARROW connecting it to a corresponding entry on the UPPER band (continuous-Indigenous-presence band) — what nation/nations were affected?

scaffold Sentence frame: 'The [event] affected the [Indigenous nation], who ARE today ___'

Manipulative Physical / non-image

12 cardstock event cards each showing: event name, year, 1-sentence summary, color-coded by thread (Indigenous Removal red; Borderlands green; Mining yellow; Railroad blue; Migration purple; Federal Law gray). Each card 4x6 inches, magnet-backed for wall placement.

Formative assessment

3 min

Exit ticket

Put these in order: Gold Rush, Trail of Tears, Transcontinental Railroad.
Why does the chronology strip have 3 parallel bands?

scoring Order correct (Trail of Tears 1830s-50s → Gold Rush 1848-55 → Railroad 1863-69) AND 3-band explanation = mastery

Teacher notes

MG-4 chronology strip becomes the unit's spatial-temporal anchor — refer back to it in every subsequent lesson. The 3-band structure is critical: the upper Indigenous-continuous-presence band prevents the textbook habit of treating Indigenous nations as 'past' once Removal is studied. Send MG-15 caregiver letter HOME at end of this lesson — 48 hours before Lesson 6. Email follow-up to caregivers who do not return the form. Verify counselor availability for lesson 7.
