Español conversacional para extranjeros - slang

Hey there! How are you? Before talking about work, I'll tell you a little bit about myself :)
I'm Pili, I'm from Argentina and in 2021 I will move to the US for a cultural exchange for the next two years. I am very excited! I took courses in photography, fashion, Digital Marketing, among several others. I am an outgoing person and a little goofy. My American friends say I'm "a firecracker".

I am not yet a teacher of Spanish or English (I hope to graduate in 2022), but I do have experience teaching mainly friends or children / teenagers with their studies.
Personally, I would like to teach the basics and classical, but also a our (Argentinian) slang and phrases that perhaps elsewhere are not taught, since in a conversation with a native, it is necessary to know them. What's the use of knowing how to conjugate a verb if we don't know what they're saying because they asked us something using slang, right? (I can also teach you Chilean, Mexican, Colombian, Venezuelan slang, as I have friends from those countries who can help me with it)

Regarding to classes, I teach online at a time agreed beforehand with the student. The first class is always introductory, in order to get to know each other, create a bond and find a way of teaching according to the student's personality. I believe that not all of us learn in the same way and that is why I like to create study plans according to the student's schedule, personality and what they really want to learn.

Hope to hear from you!
Pili
