From The Washington Post: You could say that Perea Blackmon’s classroom is a zoo, but it’s not because the students mis­behave. Blackmon’s class at the Langdon Education Campus in Northeast Washington is home to a hamster, a rabbit, two iguanas, four leopard geckos and several dozen Madagascar hissing cockroaches. But her third- and fourth-grade students are learning much more from the animals than from an occasional field trip to the zoo. “You can do everything with them. You can do a science lesson, you can do a math lesson, you can do geography . . . or a writing assignment,” Blackmon said.
