Static passing isn’t necessarily game-like but is good for coaching technique and individual coaching. Using repetition to coach correct technique will create confidence and better passing in a game-like situation.
For younger players, keep in mind passing isn’t a hugely important part of the game. The technique of ball mastery, control, and dribbling is more critical at 5-7 years. The concept of understanding why the ball is passed (to move the ball into a more advantageous position in a game) in the game of soccer can be discussed.
