This is a shorter version (one class period) of the longer more detailed file of the same name that I also have listed. It includes a brief historical summary of pre-1492, the Age of Exploration, a quick detail of Columbus' voyage, Spanish and Portuguese colonies in the New World, consequences of the conquest (war, religion, slavery, disease, the food and plants of the columbian exchange between the new and old worlds), and current controversy around Columbus Day as a holiday. Last slide includes 7 review and discussion questions for either a written or class discussion.
If you'd like the longer 2 class length thorough overview see my other listing "Columbus Day Historical Overview". It is also self-explanatory enough to print out and give as a reading assignment.
Also spelled Colombus day
