Kids Say the Darnedest Things About Note Values

The slow All-Region sax etude for high-schoolers this year starts with a double-dotted quarter note, so there's been a lot of (relatively easy) math this week while introducing it.

ME: So if the first dot adds half the value of the note, and the second dot adds half the value of the first dot, how long will the whole thing be?
KID: Almost two.
