What Are Common Signs of Hyperactivity in School with ADHD? 

School hyperactivity signs of ADHD can significantly impact a child’s ability to participate in classroom activities. Children with ADHD often exhibit behaviours such as fidgeting and restlessness, constant movement, and interrupting class, which can disrupt both their learning and that of their peers. Recognising these signs early is crucial for identifying ADHD and providing appropriate support. 

Fidgeting and Restlessness 

Children with ADHD often struggle to stay seated or keep still. They might tap their feet, squirm in their seat, or play with objects like pencils or paper. This constant need for movement is a way to self-regulate their energy, but it can interfere with their ability to focus on tasks and follow classroom routines. 

Constant Movement and Difficulty Staying Seated 

Children with ADHD may find it challenging to sit still during lessons, often getting up from their seat without permission, walking around the classroom, or moving about unnecessarily. This behaviour can be disruptive to the class, as the child struggles to remain engaged in the task at hand. 

Interrupting Class and Speaking Out of Turn 

Children with ADHD may also interrupt class, blurting out answers, or speaking out of turn without waiting for their turn. This impulsive behaviour is another common hyperactivity sign and can affect their ability to participate in group discussions and follow classroom protocols. 

In conclusion, school hyperactivity signs of ADHD include fidgeting and restlessness, constant movement, and interrupting class. Identifying these behaviours helps teachers and parents work together to provide the child with strategies and support to thrive in the classroom.
