Here's a way to practice rolling R's

I had a friend from Cuba who was in grammar school in the 30's. He said this was the practice drill that was used to teach them when roll their R's. And it was good practice. Ere con ere cigarro. Ere con ere barril. Rapido corren los carros, Sobre los railes del ferrocarril. As I remember it, he said in addition to the double R's, you should also roll the R if it is the first letter in a word.

Thanks, I am terrible at rolling my Rs! Maybe this will help! I am new to the Spanish language. What is the translation? Thanks, Timaca
