Activities appear in the Actions section of the frame; starting an activity amounts to creating an active instance of it, represented in the activity ring. They can be started with a single click. An activity may also be directly manipulated; dragging an activity into the ring will also start it.

Visual cues differentiate between instances of an activity and the [[#Activity_Icons|activity icon]] in the frame. Specifically, any activity installed on the system and appearing in the Actions edge is drawn as a white outline stroke, with no fill. Upon instantiation the icon receives a fill; both stroke and fill colors  match the XO colors of the child who created it.

Newly created activity instances inherit the scope of the view in which they are created. This means that any activity started from the Home view begins as a private one by default. Children may later [[#Sharing_Activities|share]] private activities, opening them up to friends, classmates, or anyone on the mesh through an [[#Invitations|explicit invitation]].

Since newly created activities inherit the scope of the view, any activity started directly from the Friends view will be open for friends to participate. [[#Implicit_Invitations|Implicit invitations]] are sent to all of the friends in the view, alerting them of the activity. Likewise, any activity started from the (unfiltered) Mesh view will be open to everyone on the mesh, although invitations are not sent.

The views provide scope for instantiating activities. For finer granularity, the search (located in the Frame) provides an incremental filtering system that enables arbitrary selection of scope. As a query is entered into the search field, the view—Friends or Mesh—dynamically updates to reveal the matching selection. Matches remain in color, while those filtered out appear with a white outline. The filter terms apply parameters such as the names of activities, the types of activities, the names of individuals, and the interests of individuals.  For instance, a child could search for anyone who likes games before starting a new game of Memory, or everyone in her grade in a classroom setting, or a specific group of individuals by name. The results of the query become the scope for any new activity instance, and all XOs within that scope receive implicit invitations when an activity begins. These groupings may be saved as groups for future use.
