How to teach my little brother Chess.
Give him the book: Bobby Fischer teaches chess.
strange that the op did not respond to the helpful posts but focused on the trolling, actually vindicating soups.
Kids are extremely difficult. Read my story.

How old is he? Don't teach a lot in one get go. But repetition is the key. Maybe in a couple of days teach how the pieces move and capture. Do these in a chess board. Once you demonstrate how a piece capture give some exercises to see if he learn what you are teaching. Then teach how the game is won by showing back rank mates or simple mates that you can think of. Once he learn mate, teach how pieces are placed at the beginning of the game. The important thing at the end of your teaching, give him exercises.
Let say your brother fully grasp how the game is played, show more mate problems and tactics that win materials like pin and fork. If you want him to get better, letting him solve one or two puzzles a day is enough.
Maybe these links can help you.
