I want to work on a Team Project with 3 Students in Portugal and NYC, can they get one month free?

Hello, 
My classes went online and I want to show off. I have some fun honors students redistributed in Portugal and NYC who would like to edit with me in Premiere. 

The school has a Covid EDU access for students but they have to pay $35 a month to access Teams and annual seems the only choice.

Can we all just try it for a month? My account seems to provide it for free... but I am the Prof and I want some joy to come to the school and the students.

If we can't get Teams access free for 3 studetns for a month... can we get it for one month... and not have to pay too much for a year just to give it a try in an independant way?
