2026 Indiana Academic Standards: K-12 Social Studies

Teacher's field guide

What Students Need to Do: Students identify what people did together and how others responded. They explain how that shared action could lead to a change in rules, attitudes, or daily life.
What Mastery Looks Like: A student can explain how the Montgomery bus boycott put pressure on the bus system and helped bring attention to segregation. They can name the court ruling that changed bus seating rules without claiming the boycott alone caused it.
Common Misconceptions: Students may think any large crowd is a social movement or that a protest changes a law right away. They may credit one leader and miss the work of many participants.
How to Assess It: Exit ticket: “Montgomery residents boycotted city buses and organized carpools; bus revenue fell, and a court later ruled bus segregation illegal.” Name the shared action, one response, and the change.

Lesson moves

Hand out cards labeled boycott, carpools, lost bus fares, court ruling, and integrated buses; students arrange them and draw arrows between connected events.
Ask, “Would a viral post about unfair bus fares change a policy on its own?” Have students name an action people could take next.
In pairs, match cards for panic buying, a school petition, and a boycott to possible responses; explain one match aloud.
Draft a petition to change a school lunch rule, then name who would decide and how students could check whether anything changed.
