Cub Scout Program Helps is a great resource for Cub Scout leaders. It contains a month-by-month breakdown of suggestions for den (Tiger, Wolf, or Bear) and pack games, songs, advancement ceremonies, crafts, and other activities to go along with the Cub Scout Monthly Themes.
BSA National has now posted a downloadable single pdf file of the entire 2008-2009 Cub Scout Program Helps.
