This worksheet has twenty different sentences that use present, present progressive, and simple future tenses to describe what someone is doing. The students read the sentences and then decide what the best command would be based on the information in the sentence. For example: "Yo estoy aburrido. Yo voy a dormir en la clase." The student would read the sentence and decide what the best command would be. They would most likely write "No te duermas en la clase". This worksheet can be fun because the students begin to argue with one another about whether or not the command should be affirmative or negative. In the example I gave, some of my students would say that if the class was boring then they should create an affirmative command and tell the person to sleep.
