Sanket Jain here, a passionate web developer pursuing a professional career in the same field. I started programming at an age of 15 and continued with this and secured my bachelors degree in computer applications.
I will start with the basics of programming and how fun it can get for him. Expose him to different programming languages and their applications. Then get his response on the ones he wants to pursue.
Then teach him basic sytanx and baisc programming. We will then move on to small program assignments, selected tutorial videos to watch as home work and screen shares live sessions and work with live projects.
Hope to hear from you soon.
