This is a two-page worksheet/ review sheet about ser and estar in the imperfect Spanish tense. The sheet opens with two tables to put the conjugations for ser and estar in the imperfect tenses. Then, there are places to list common uses/clues for when to choose ser and when to choose estar in the imperfect. Next, there are sentences that require the student to choose between a form of estar and a form of ser in the imperfect to best complete the sentences. After that, there are sentences to translate from English to Spanish. This is a great review sheet, class practice, or homework assignment.
