Simon, a student, is exhibiting behaviors consistent with ADHD such as difficulty paying attention, hyperactivity, and impulsivity. These behaviors are interfering with his learning and could lead to long-term issues. Mr. Chan, Simon's teacher, should collaborate with parents and the school's support team to create an individualized plan for Simon. This may include environmental changes in the classroom, teaching Simon organizational strategies, breaking tasks into smaller steps, and providing clear expectations and consequences for behaviors. The goal is to help Simon better manage his ADHD symptoms and succeed academically and socially.
