Lesson 2 55 min hist.g4.s.lesson_02

US Physical Geography — 5 Regions, Major Landforms, Rivers, Great Lakes

Objectives
  • Students locate the 5 US regions (Northeast/Southeast/Midwest/Southwest/West) plus Pacific Northwest sub-region plus Alaska and Hawaii on MG-2.
  • Students name 5 major mountain ranges, 7 major rivers, and the 5 Great Lakes.
  • Students apply NCGE Five Themes of Geography to one US region.

Lesson plan

Warm-up

5 min

Locate YOUR state on MG-2. Tell partner which region your state is in and one neighboring state.

Teacher moves
  • Walk room to support state location
  • Affirm regional placement
  • Note state-pair patterns by region

Direct instruction

15 min

Direct teach the 5 regions with hand gesture (right arm = Northeast/Southeast; left arm + low body = Southwest/West/Pacific Northwest; midline = Midwest; separate gesture for Alaska + Hawaii). Name 5 major mountain ranges with location (Appalachians = Southeast/Northeast spine; Rockies = West central; Cascades = Pacific Northwest; Sierra Nevada = California-Nevada border; Coastal Range = Pacific coast). Name 7 major rivers + their watersheds. Name 5 Great Lakes via mnemonic HOMES (Huron/Ontario/Michigan/Erie/Superior).

Key examples
  • Geography matters because landforms shape what humans can do — and what work it takes.
    model Sierra Nevada — this is the same mountain range Chinese laborers had to blast through to build the transcontinental railroad's Central Pacific section, which we'll study in lesson 14.
    prompt Which mountain range runs north-south through California and Nevada?
Checks for understanding
  • Tell partner which region your state is in.
  • Name two states in YOUR region and one mountain range or river in your region.
Sourcework

Children examine MG-2 as a cartographic source — who made this map? What does it include and exclude? (Note that Native Land Digital overlay is on a removable layer.)

US 50-State Physical and Political Map (tactile-relief version available): full continental US plus Alaska and Hawaii insets; all 50 state outlines in faint gray with capital-city dots and state-name labels in 12pt; major landforms in raised-relief tactile version (Appalachians, Rockies, Cascades, Sierra Nevada, Coastal Range, Ozarks, Great Smoky Mountains); major rivers (Mississippi/Missouri/Ohio/Columbia/Colorado/Rio Grande/Hudson) in blue; Great Lakes labeled (Superior/Michigan/Huron/Erie/Ontario); Great Plains shaded; deserts (Mojave/Sonoran/Great Basin) shaded; climate zones lightly indicated via 5 color washes; 5 region-boundary lines overlaid (Northeast / Southeast / Midwest / Southwest / West) with Pacific Northwest sub-region and Alaska/Hawaii separately. Translucent overlay layer (removable): historic Indigenous-homelands map circa 1500 CE based on cartographic work by Native Land Digital (native-land.ca, used with permission) showing 100+ nation-names across the continent. Style: cartographic accuracy, child-readable labels, tactile-raised landforms.

Guided practice

18 min
Tasks
  • Region card sort: sort all 50 state cards into 5 region piles + Alaska + Hawaii piles.
    scaffold Use MG-2 as reference; work in pairs.
  • Apply NCGE Five Themes to ONE region (your own region): LOCATION (lat/long), PLACE (physical features), HUMAN-ENV INTERACTION (how do people use the land?), MOVEMENT (what comes in/out?), REGIONS (sub-regions).
    scaffold Use NCGE Five Themes anchor chart.

18x24 chart showing the 5 NCGE themes (LOCATION/PLACE/HUMAN-ENVIRONMENT INTERACTION/MOVEMENT/REGIONS) each with child-facing definition and a US-region example. Color-coded per theme.

Formative assessment

3 min
Exit ticket
  • Name the 5 US regions.
  • Name 2 mountain ranges and 2 rivers in the US.
  • Which region is YOUR state in?
scoring All 3 prompts correct = mastery; 2 correct = practicing; 0-1 = reteach

Closure

2 min
Moves
  • Restate why geography matters for human history
  • Preview tomorrow's 50-states + capitals work

Homework

8 min
Tasks
  • Find a US map at home or online. Identify ONE landform within 200 miles of your home you have visited or seen. Write 2 sentences.

Differentiation

Scaffolds
  • Tactile relief map for non-visual readers
  • Region color-coding
  • HOMES mnemonic poster
  • Bilingual landform names in 8 heritage languages
Extensions
  • Stretch students locate continental divide and explain east/west watersheds
  • Stretch students name 3 deserts (Mojave, Sonoran, Great Basin) and the climate zone difference
English Learners
  • Pre-teach 'region', 'range', 'basin' with picture cards
  • Tactile-pointing answers accepted
Ieps 504s
  • Pre-cut state cards for sort
  • Reduced-set sort (10 cards into 2 region piles, scaffolded to full set)

Teacher notes

Region terminology varies by source — Census Bureau uses 4 regions (Northeast/South/Midwest/West); NCGE often uses 8 with Pacific Northwest separated; this unit uses 5 + PNW sub-region + AK + HI as the most child-accessible structure. Be explicit with children that maps reflect cartographer choices — there is no single 'true' region map. Use HOMES mnemonic; do not skip the human-environment interaction theme as it sets up later economic-history lessons.
