The conversational style of the sentences (Some exercises are actual dialogues, which could make good oral language practice.) in this practice sheet makes it perfect for ELD class or native speakers. The five exercises here encompass regular and irregular verbs, past and present tense, affirmative and negative, and declarative and interrogative forms. Learners fill in the blanks in each sentence using the correct form of the given verb. I'd assign pairs to complete, rehearse, and present to the class.
