Teaching Games for Understanding - Activity Support Package is a terrific resource from OPHEA.  This resource provides various small-sided games that will help kids understand common concepts in many traditional sports.  The intent is to teach concepts rather than specific sports.  

Games are separated into four categories:  Target, Net/Wall, Striking, and Invasion/Territorial.  Educators, coaches, and program coordinators can all use this valuable resource to support the physical literacy development of kids.
