Often, they forget to plan ahead by writing down the assignment or bringing home the right books. And when trying to work, they find their mind drifting to something else. People who are hyperactive always seem to be in motion. They can't sit still and they may dash around or talk non-stop. Sitting still through a lesson can be impossible.
Hyperactive children squirm in their seat or roam around the room.
Or they might wiggle their feet, touch everything, or noisily tap their pencil. They may be fidgety, restless, and try to do several things at once. People who are overly impulsive seem unable to curb their immediate reactions or think before they act. They may blurt out inappropriate comments, or they may run into the street without looking. Their impulsivity may make it hard for them to wait for things they want or to take their turn in games.
