Students first write the regular present tense -ar, -er, and -ir endings, then conjugate the verbs given in the present tense. Verbs are organized by "regular verbs", "stem-changing verbs", and "irregular yo verbs". All forms of the verb that require a spelling change are outlined in bold lines; this is great for visual learners! This assignment is straight forward and utilizes repetition as a learning tool. Great for homework, quizzes, or review.
