While Henri Rousseau's work was not easily classified into any definitive artistic style of the time--impressionism, post-impressionism, fauvism, or cubism--it has been considered a forerunner of surrealism because of its dreamlike sensibility. This teaching guide provides information about Rousseau and his work, focusing on "Tropical Forest with Monkeys." The guide also discusses the key concepts in Rousseau's painting. It provides photographs of five of Rousseau's works and suggests activities for elementary school, middle school, and high school. (BT)
