The sentence "I can how to swim" is incorrect. The correct way to say it is either: "I can swim." or "I know how to swim." The phrase "I can" means you have the ability to do something, while "I know how" means you understand the method or process of doing something. Anyway Your way of teaching is great! Go on ♥️
