Use be going to _____(base verb) to talk about a future that was planned. Some websites have tests that indicate "be going to" is very different from "will." In real life, the difference is very small. We usually start with "be going to" for a plan and "will" for first volunteering or considering possibilities, but if we keep talking, we may use them interchangeably.
Going to is pronounced like (a cup of mustard) "gonna." Even though lots of people--and many lyric writers-- write "gonna" especially in texts, it's not OK in a formal situation. You should write "going to" and say "gunna."
For regular verbs, add _ed to show past in a positive sentence. They listened to me.
Use Did and the base form to show past in a question. Did you listen to me?
Use didn't and the base form to show past in a negative sentence. He didn't listen to me.

Just a song with some past tense verbs -- "Summer Nights" from Grease
I really like this next video except for two tiny points. I think we often put two verbs together in continuous and perfect tenses. In those cases, however, one of the verbs is always a form of be or have.
Also, when there are two syllables or more, we only double the final consonant before the ed if that syllable is stressed. For visit, we stress vis, so we don't double visited. Both the British and American versions of traveled are correct because British people stress the vel more than Americans do. Students shouldn't have to memorize long lists of which verbs double the final consonant before the ed.
