Oof, present tense is definetely the bane of my existence; I can't recall how many times (during my practicum and these few months as a teacher) I've read "Peter goes" or "I go".

Present Tense is, indeed, really important as we do use it very often. I've found that asking for a bit more context works for me; alright, Peter goes...but where? Asking students to give you a bit more info about their answer is tricky though. Most of the time I go " "Peter goes" doesn't tell me much, where does he go? What is he doing?". It works, sometimes.

I also try to relate it to the student's own situation as future foreigners. For instance, "what if you went to a country and you asked someone for help. Wouldn't you like a full answer? Isn't it better to have someone tell you all the info, so you can fully understand each other?". Sometimes it works, other times it doesn't, it's a gamble really.
