How is Cassie's school different from the one that the with children attend

Cassie looks at the white children's building, Jefferson Davis County School, and notices that it has two school buses, a sports field, and the Mississippi flag with the emblem of the Confederacy on it. The black children turn east to head to their school.

They go to Great Faith Elementary and Secondary School, "consisting of four weather-beaten wooden houses on stilts of brick, 320 students, seven teachers, a principal, and caretaker, and the caretaker's cow." Most of Cassie's classmates are children whose families sharecrop on three nearby plantations. They start school late because their families need them to pick cotton until October.
