The ADHD brain craves stimulation. If he’s getting up and looking elsewhere, he’s likely bored and not getting the stimulation he needs to stay focused on what you’re doing. Think about how you can change up the activities you’re doing to make them more stimulating — can you add physical movement? Music? Etc.
