Students create a crossword puzzle in Spanish preterito using 15 different verbs. They will create 15 different sentences in the past tense, removing the verb for the clue. The verb is placed in the grid to create a crossword. Alternatively, you could have the students highlight the boxes to be used for the answer, and can give their puzzle to a partner to complete instead. Makes for the perfect sub plan, extra credit, or 'extra time" activity. There's a check list for students to make sure they complete the assignment correctly.
