Clients use toys to create scenes in a tray of sand, and the therapist observes how they arrange the toys. The therapist and client then discuss the toys, their arrangement, and any symbolic meanings. 

Sandplay therapy can help children with ADHD express and process their emotions and experiences, and can improve symptoms like hyperactivity, impulsivity, and inattention. 

Studies have shown that sandplay therapy can be effective for children with ADHD, and can also help with other psychological issues like anxiety, depression, and trauma. 

Sandplay therapy is most effective for children between the ages of 3 and 12, but it can be used for other age groups as well. 

While sandplay therapy can be a promising treatment, there are ethical and practical considerations, like therapist training and treatment cost. More research is needed to determine its long-term effectiveness.
