To be used with the video "History of the World in Two Hours" students fill in blanks as they watch the video, use to study then take quiz. The study guide and quiz utilize the first half of the video (prehuman) since the rest of the year's lessons pick up with the Mankind - The Story of All of Us videos. This short unit is the introduction to what came before humans and how we got here. I show the first half, review the study guide, give the quiz then show the second half of the video History of the World in Two Hours. The unit can take about 5 class periods if used this way.
