In Italy, can I buy a travel/discount pass that covers trams, metros and intercity travel?

Question

I am traveling with my family to Italy from May 24th to May 29th. We plan to cover Rome, Florence and Venice. Hence our travel will include Tram/Metro travel within these cities as well as intercity train travel between Rome - Florence and Florence - Venice. Are there any travel/discount passes available that I should buy, which can make my travel cheaper? Or should I just buy tickets individually everytime I travel.
