If you are teaching a class with one or more students with ADHD, you might find that assigned seating works best for your class. Since children with ADHD work better with certain seating arrangements, you'll need to control where ADHD children sit in your classroom. This can be difficult in a classroom setting where the other students get to pick where they sit. Therefore, it's probably best to assign all seats.
It's a good idea to seat students with ADHD in a place where you can be available to help redirect them while working on assignments. Students with ADHD may frequently wander and daydream during seatwork, so a gentle reminder may be beneficial. Reminders shouldn't be negative, or viewed as punishment. Instead, they should be a quick redirection, aimed at refocusing the student when needed.
Choosing a seating location in the classroom that is free of distractions is a must. Keep students with ADHD away from windows and doors that lead to hallways. If your door happens to be open, they will most likely find whatever is happening in the hall much more appealing than finishing their assignment. Any other obvious classroom distractions should be avoided as well.
