as a dad of a 12, 9, 6 yr old girls, i just let mine be and they figured it from watching me and others. my 12, 9 and me tear it up on anything we want. and it so cool doing with your girls. just hang in there ,dont try teaching them, they wont listen anyway,save your money on the lessons for when they are a little older. its frustrating now, i was tortured for 8yrs.dont worry , it gets so much better, trust me
