Learn Telugu from basics

I am Sandhya Nayaka from Jadcherla, telangana, India. I have done an M.Sc in mathematics. My English is not that fluent but I can communicate well. Since my childhood, I am speaking Telugu and most of my studies were also in Telugu medium. I have been living in Sweden for the last three years. I am a housewife taking care of two kids. Now, kids are grown up. So, I want to use my free time to teach Telugu. I would like to take a similar route through which I learned Telugu when I was a kid. First, I will start with the Telugu alphabet and small words. Next, I will move on to teach small sentences by talking with them in Telugu.
