From House Seats to Districts | Dynamic History Module | Grades 9-12

Teach apportionment and redistricting through a concrete Oregon case study. In this two-day Dynamic History investigation for grades 9-12, students begin with Oregon gaining a sixth U.S. House seat after the 2020 census and follow the separate process that turned six seats into six congressional districts.

Students use Supreme Court cases, Oregon's 2021 districting process, Portland-area maps, city and ZIP-code examples, and a land-area comparison between Districts 2 and 6. The module repeatedly asks students to separate equal population from equal land area and to distinguish what a map can show from what it cannot prove about political motive.

What students investigate

• Oregon's sixth U.S. House seat after the 2020 census
• Baker v. Carr and the justiciability of constitutional districting claims
• Wesberry v. Sanders and the equal-population principle for congressional districts
• Oregon's 2021 congressional redistricting process and six-district map
• Four congressional districts meeting in the Portland metropolitan area
• City limits, ZIP codes, and congressional district boundaries
• Oregon District 2 and District 6: nearly equal populations with very different land areas
• The final distinction between gaining a House seat and drawing its district lines

State and local classroom connection
