What This Standard Means
What Students Need to Do
- Students explain how the ten-year census count helps determine each state's number of U.S. House seats. They explain how states redraw district lines and how Baker v. Carr allowed federal courts to hear challenges to state legislative districts.
What Mastery Looks Like
- Given a population change, students can tell whether a decision concerns House seats among states or district lines within a state. They can explain that Baker v. Carr let courts hear districting challenges, but did not draw the districts.
Common Misconceptions
- Students may think the census counts only voters or draws district lines. They may confuse assigning House seats to states with redrawing lines within a state. Some think Baker v. Carr set exact district sizes.
How to Assess It
- Ask: “A state gains a House seat after the census. What happens in reapportionment, what happens in redistricting, and what did Baker v. Carr allow courts to do?”

Ways to Teach It
Give pairs a 3-by-4 grid with 100 residents per square; have them draw three connected districts of 400 residents each.
Ask students to write one sentence answering: “Why can a federal court hear a challenge to unequal state legislative districts?”
Have students sort cards labeled “census count,” “House seats per state,” “new district lines,” and “court challenge” into order.
Compare your state's House seat totals after the 2010 and 2020 censuses, then count districts on its 2022 congressional map.
