Handout in Word document contains 50+ fill in the blanks for students to practice using the Preterit vs Imperfect. The sentences are loosely based on the short story "Jacque Mate en dos jugadas" written by German-Argentine Isaac Aisemberg. Can be used as a review and later as a quiz. I usually divide the worksheet and do one half for a review and the second half as a quiz. Key is provided.
