Final answer:
Grant's difficulty sitting still, wandering attention, and impulsive behavior suggest he may have ADHD, a condition that affects classroom performance and attention regulation.
Step-by-step explanation:
Eight-year-old Grant is exhibiting symptoms that suggest he may have Attention Deficit Hyperactivity Disorder (ADHD), a neurodevelopmental disorder which is characterized by difficulty maintaining attention, and controlling impulses.
These symptoms include an inability to sit still, a wandering attention span, and impulsive behaviors. It's important to note that ADHD can make it hard for students to follow instructions, leading to problems in academic performance and classroom learning experiences. Additionally, ADHD symptoms often lead to frustration and distraction. It is more prevalent in males and those affected may also have comorbid conditions, such as depression or OCD.
