Lego Therapy is a social skills intervention that motivates children to work together by dividing the tasks into different roles. One child is the Engineer (describing instructions), another child is the supplier (finds the correct pieces), and another child is the builder (puts the pieces together). This intervention showed a reduction in maladaptive behavior and improvement in their socialization and communication.
