Research shows there are an estimated 3 to 5 percent of school-age children with Attention Deficit Disorder/ADD/ADHD/Dyslexia. In response to the needs expressed by teachers for teaching strategies that work with these children, the U.S. Department of Education has supported research in classrooms to determine successful teaching techniques employed by elementary (primary) schoolteachers to keep children focused on task.

The following tips, for experienced and inexperienced elementary (primary) schoolteachers alike, are tried and true methods for reaching children with ADD/Dyslexia. Children with ADD/Dyslexia, typically have problems with inattention, impulsiveness, and hyperactivity. They often have difficulty paying attention in class and seem to shift aimlessly form one unfinished activity to another. These children generally appear restless, fidgeting constantly in their seats, playing with pencils or other objects, or disturbing nearby students. Many children with ADD/Dyslexia also have difficulty following their teacher's instructions or forming friendships with other children in the class. Like other children with disabilities, children with ADD/Dyslexia learn best when their teachers understand their special needs and individualise their educational program to meet theses needs.
