If you choose to teach the unit as a whole, it may be useful to envision the timeline you are working with. The unit starts in the late 1940s as the term “rock 'n' roll” comes to the forefront. The unit content covers a basic exploration of how rock 'n' roll evolved from rhythm and blues. It continues into the mid-1950s/early 1960s as the Vietnam War begins, and the United States enters into the fight. We introduce the Beatles and other players of the British Invasion, and continue through notable Civil Rights events and Dr. Martin Luther King, Jr.'s assassination. As the Vietnam War continues through the mid-to late-1960s, the unit explores the pro-war side, and the counterculture.
