What This Standard Means

What Students Need to Do

Students use a map to explain why the Army placed Fort Sill near the Kiowa, Comanche, and Apache reservation. They explain how Buffalo Soldiers carried out federal orders that affected Native people.

What Mastery Looks Like

A student can locate Fort Sill and explain how its location helped the Army enforce reservation policy. They can identify the 10th Cavalry as a Black Army regiment and give one example of how troops carried out orders.

Common Misconceptions

Some students think Buffalo Soldiers were Native American soldiers because of the name. Others think forts only protected settlers, or that soldiers made the policies they enforced.

How to Assess It

On a map of Indian Territory, mark Fort Sill. In two sentences, explain why the Army placed a post there and how soldiers helped enforce reservation policy.

Ways to Teach It

  1. Give pairs a map of Indian Territory; have them mark Fort Sill, the nearby reservation, and routes troops could patrol.

  2. Ask students to write: Did Buffalo Soldiers make federal Indian policy or carry out orders? Give one example.

  3. Give pairs cards labeled Fort Sill, 10th Cavalry, reservation, patrol, and federal order; have them build and explain a cause-and-effect chain.

  4. Compare an 1870 Indian Territory map with a current Oklahoma map; find Fort Sill and identify the land's earlier reservation boundaries.
