With this worksheet, students have to read and analyze (annotate) sentence structures including "ser" with adjectives, "gustar" with verbs, and conjugated -ar verbs. They will read, annotate, and translate into English.
There is also an extension in which students have to use all three sentence types as well as greeting terms in order to create their own dialogue. They can work individually or in pairs to do this. You can have students practice and perform their dialogues if you want to, so the time you take with this can vary widely.
