My VAK scores show I have a strong Audio angle. Which suits me because I am good at music.
I would have loved to learn songs in maths to help me remember stuff.
I am learning my 3x tables at the moment with Jack Johnson. He has this "3R's" song and he sings the 3x table in the middle of it. And EVERYONE knows how cool Jack Johnson and Curious George are :P
Here's a youtube link:
The 3x tables bit is near the end. I sing it all the time. I can nearly do the whole 3,6,9,12 thing forwards... backwards is another matter - but at leat I'm trying! hee hee
Another way to have music in your classroom is to take common classical songs and make up your own words to them. Rhyming is really good for memory help, as is alliteration.
I can STILL say in German : "I have two eggs and this is tea" - but only in a sing song voice to The Blue Danube...
Using well known classical music is good becuase people know it, though they'd never admit it, and they don't have to "learn the music" before they create the words.
Rap also works... though I can't do it, the boys are really good at it.
If questoined about the approach you are taking with maths simply fall back into the "alternative learning styles" approach. Tell them you are being pro-active with those students in class who have a AVK or AKV learning style.
You could even do the VAK test with them before you set out so you have "proof" they learn through music. There's heaps of printable ones on the web
Good luck. I'd love to be in your maths class if we got to make music and sing etc
