I'm a teacher - which informally can be a role taken on by anyone but I teach middle school math
Wow that's great, I love teachers
I love it although preparing lessons and assessing progress can be tedious.  Do you have a favorite teacher you remember?
Yes I do, he had a funny name he is late now. His name is Japan. I wonder what skill one needs to become a teacher
In some countries teaching young kids can be done informally, like homeschooling, where you don't need skills. 
What does it take to became a teacher in USA?
formal teaching of students usually carried out by pain professionals who have gone to college and also taken certification exams in various subjects. 
Amazing, thanks for the information. I would check it out because I want to be a teacher
