Veinte y cinco vs. veinticinco

I have been teaching numbers over 20 the same way that I was taught in high school.. with the three word method: "Veinte y cinco" = "Twenty and five." I find this the easiest to understand, which is why it is the method I have chosen to teach.

I've been alerted on several occasions that it is far more common to use the one word method: "Veinticinco," but I have shied away from it because of the spelling change in the tens place and for general ease of teaching.

Should I start with the three word method at the elementary level, then introduce the alternative at the middle school level? After all, it would be beneficial for them to know both. Or, should I start off with the one word method straight off?
