30-minute activities for 12 year olds
You have 30 minutes and a 12 year old. That is a real constraint, and most activity lists ignore it entirely. Twelve year olds engage best when there is genuine skill, choice, or a real outcome involved.
Everything below genuinely fits in 30 minutes or less, including setup. Nothing that takes twenty minutes to prepare for five minutes of play.
