Voy + a + infinitive is a fun construction because it gives students the ability to talk about the future without too much trouble. It’s also fun to teach through music because there are several good songs for it. The first is ‘Irreemplazable‘ by Beyonce, always fun because the students know the English version. It has three unique and at least 9 repetitions of voy a constructions.
Another song that’s good for this is new on my radar, El amor de mi tierra by Carlos Vives. It has four occurrences of voy a.
