In "To Kill a Mockingbird" where do Jem and Scout go with Calpurnia?
In chapter 12, Atticus leaves town and travels to Montgomery for legislative work. Calpurnia ends up taking Jem and Scout to First Purchase African M.E. Church for Sunday service, where the children get an inside look into Maycomb's black community. The Finch children learn that the majority of the congregation is illiterate, which is why there are no hymn books, and are astonished to witness how the members use a technique called "lining" to sing the hymns. They also watch as Reverend Sykes collects ten dollars to support Tom Robinson's family and discover that Calpurnia lives a "modest double life." Jem is also suprised to discover how Calpurnia learned to read and gains a new respect for her after visiting the church. Overall, Jem and Scout gain valuable insight into the black community after attending Sunday service at First Purchase African M.E. Church in chapter 12.
Atticus is out of town, and Sunday approaches, so Calpurnia decides to take them to her church, because the last time they went to church without Atticus they had gotten into a lot of mischief. Her solution is to keep them close. She cleaned them up all nice and took them with. Here they encounter the surly and confrontational Zula, who accosts them with "you ain't got no business bringin' chite chillunhere-they their church, we got our'n", and Zeebo who steps in to defend them and leads the hymns by singing them first, line by line. They hear about the collections being taken up to support Tom's wife, and overall, it is a nice little trip. All of this is in chapter 12; I provided a link with a summary below.
