This PowerPoint explains how to use the 6 forms of gustar in the present tense and how to pair gustar with infinitive verbs/activities/objects/etc. The slides' animations make this learning process easy to follow and compartmentalizes the different components of gustar. The last couple slides have answers to activities that correspond with the Avancemos 1 textbook, but you DO NOT need this textbook in any way for this to be a successful lesson for introducing gustar.
You may additionally purchase the "Gustar with an Infinitive Skeleton Notes" for $1.00 that corresponds with this presentation. These notes are a great way for students to follow along with the presentation and have a hard copy of notes that they can use throughout the gustar unit.
