Numbering raffle tickets in word

I am not a computer genius but once I understand I can get through it. I downloaded a template for making raffle tickets and it gives you a nice one using Avery paper products. The tickets are numbered 1 to 5 and I need to make 2000 tickets and really don't feel like numbering each ticket myself. How do I format the template so that it will make more than one page of tickets numbered higher than five? Does anyone know how to do this?
