For online lessons I use all possible free materials in the Internet. For beginners I make a little list of greetings, question words, most important verbs, numerals, and substantives. I teach how to make a small talk, order food, ask for directions, and other essential topics. 

Advanced learners I teach according to their needs and interests. I can give a lecture about the structure of Estonian or Finnish language but also, I can have conversation about various topics. Of course, writing exercises are possible as well. 

I make my lessons relaxed and peaceful. Everyone should feel confident and have a sensation of success during my lessons.
