WORD 2007 Two page template?

I want to create a two-page template. For instance, want academic flash cards to have two sides. Example: One page with six cards for front side (word) and one page for back side (definition).

User will use template to create multiple cards. Let’s say user needs 12 cards (six per page). If page one is the front of six cards, page two is the back those same cards, then user needs page three (front), then four (back). How do I get it to default to the first page design (front of cards) for odd numbered pages and page two design (back of cards) for even numbered pages?
