No two people experience ADHD the same way. It can make it hard to focus or hard to keep still. ADHD is a complicated condition that affects people of all ages. Find out why it's important to get a diagnosis and how to be a good friend to someone who has ADHD. Level 3 readers are aimed at children who are reading by themselves and can grasp new concepts. Key words and captions help readers understand new vocabulary and more challenging sentence structure. ¿This project has been made possible in part by the Government of Canada.
