A very simple way of talking about the future, is to say ‘I’m going to……..’ The Spanish do it too!
First you need to know the verb IR – to go
IR – TO GO
|VOY||I go||VAMOS||we go|
|VAS||you go||VÁIS||you go|
|VA||he/she goes||VAN||they go|
When you know that, you just add ‘a’ & the full form (infinitive) of the verb that describes what you are going to do.
IR + a + FULL FORM OF VERB
So, if I want to say ‘I’m going to swim in the pool’ I say
Voy a nadar en la piscina
Are they going to go to school? –
¿Van a ir al colegio?
& negative – We’re not going to sing a song
No vamos a cantar una canción
