This resource includes two different 8.5" x 11" printable posters:
-One outlines the uses of the verb ser using the acronym DOCTOR (description; occupation; characteristics; time/date; origin; relationship)
-One outlines the uses of the verb estar using the acronym PLACE (position; location; action; condition; emotion)
For best quality, I recommend printing the posters off either in color on white colored cardstock or black-and-white on colored cardstock and laminating them. Because the posters are 8.5" x 11", I cannot guarantee the quality of the posters if you attempt to resize them when printing.
