Pupils must puzzle through the imperfect tense in order to complete this crossword. Class members conjugate 15 Spanish verbs in order to complete the crossword. Each clue is made up of a verb and a conjugation (for example: permitir, third person singular). Since learners conjugate to fill in the puzzle, the activity is more challenging and educational than a typical crossword. Note: You will need to make sure your class knows what first, second, and third person mean before assigning this worksheet.
