Talking about the future is something that is done very frequently. Whether we are talking about our dreams or simply telling someone what we will do tomorrow is all spoken in the future tense. Here are some examples.

"I'm going to see Bob tomorrow"
"I'm going to meet John at the airport at 6 O'clock tonight"
"I'm going to go home in an hour"
"I'm going to go to the bus stop right after class"
"I'm going to do that tomorrow"

When using 'going to' after 'I am' it is important that a future indicator is present. For example, if I say, 'I am going to meet John', this can also be present tense that we practiced previously. But if you add a future indicator like 'at 6 O'clock tonight' then it becomes future tense.

Other future tense indicators are:

'going to go'
'going to be'
'I will'
'I have to'

Let's practice using these words:

"I'm going to be dead if I don't finish this project by tomorrow"
"I'm going to go home next week"
"I'll meet you there at five"
"I can't go tonight because I have to work late"
