The post written by Devany LeDrew, a former kindergarten teacher, includes a few great activities for crossing the midline that include easy to follow pictures.  Pediatric occupational therapists often include some of these activities during their therapy sessions.

Engaging in activities that cross the midline can be beneficial during a homework break, in the morning before school or incorporated during playtime.
