Both my daughters have ADHD, combined type. Although my older daughter loves to read, my 11 year old hates to read. It helps to find things of high interest- joke books and science facts. Until she decided she was too old this summer, we would read to her at night. If it was a mystery hook or something magical, then she would want to see how it ended and start reading herself.
We also have a subscription for her to Cobblestone magazine as she likes history. You could look into something like cricket magazine or see if the library has it or a kids Science magazine.
Books on tape are also a wonderful way to improve vocabulary and comprehension for a child who struggles with reading, or just avoids it. Not to take the place of reading, but supplement it so child gets exposed to same content and vocabulary as peers.
