Stress can negatively impact children's behavior and development. Teachers can help children cope with stress by observing for changes in behavior, encouraging positive expression of feelings, providing a calm environment, developing social and problem-solving skills, and involving parents and professionals if needed. Practical strategies include using stories, art, and physical activities to help children process stressors, as well as deep breathing exercises and establishing a quiet space to self-regulate. It is important for teachers to model stress management and maintain open communication with parents.
