“Ser y Estar: To be” is a PowerPoint Presentation that explains the differences between both verbs. It uses the acronym DOCTOR (Description, Occupation, Characteristics, Time, Origin, and Relationship) to explain when to use the verb “ser”, and PLACE (Position, Location, Action, Condition, Emotion) for “estar”. Each slide addresses one use of the verb with various examples and illustrations. The final slides provide practice for choosing either “ser” or “estar”.
