Very basic :
Multiply/divide a frequency by 2, get an octave up/down.
Add/substract at the hertz level to tune/detune a sound.
Show how notes don't have an equal size in a scale (without talking
about 12th root). It's also a good time to introduce equal temperament
and the damage done :).
Add two or more sines to create a beating. (see A08.beating.pd)
Also get a acoustic instrument with you to prove it's not about computer
magic. With a guitar you can show the different fret spaces and detune the
instrument to produce nice beatings.
good luck with the new generation :)
