Explaining the same thing three different ways to a ten-year-old builds patience no lecture can.

Patience gets built by being made to try again. Reaching for a third way to explain fractions means the first two missed, and you had to find another route, and that finding is what teaches you the subject and the self-control together. No lecture produces that, because nothing is being asked of you while you listen. Repetition under mild frustration is the actual training.

Teach somebody something this week and expect your first explanation to miss. Have a second and third route ready: a drawing, an example, a story. Watch for the moment their face changes.
