Intervention Strategies Activities to Encourage Crossing Midline Crossing midline refers to the student’s ability to cross his or her arms or legs over the midline of the body. The midline is an imaginary line that runs through the body, cutting it in half from head to toe. Students with midline crossing difficulties exhibit this by: piecing diagonal letters, turning body when writing or drawing and switches hand dominance based on which side of the body items are presented. Students need to be able to coordinate both hands together in the middle of their body before they can cross midline.
