Get him involved in FIRST LEGO League <
https://www.firstinspires.org/robotics/fll>. In FIRST LEGO League, he'll learn robotics and programming, but he'll also learn teamwork, engineering, project and time management, sportsmanship, researching, presenting, and all sorts of other useful soft and hard skills.
FIRST has robotics programs for kids from age 4 all the way up to 18 with increasing levels of difficulty, complexity, and competition. So, if he enjoys it, this could be something he does all the way through high school.
