I think that depends on your kid. I learned to code when I was 13 and I would have hated the computerless approach. I specifically remember being ~15 and someone pointing this out to me in an IRC room --- I thought that they were being pedantic. Older me now finds the stuff you do without a computer the most fun. One suggestion I might have is, depending on their age, doing combinatorial game theory with them. That sounds really hard and fancy, but it's not (at least at the introductory level). There's a lot of games that are really simple to describe (e.g. counting games, simple board games) and your goal is to figure out the smartest move and / or if the player who starts the game can win.
