How do you make reading to be less of a 'task' for kids, and more of a fun activity that they look forward to? My son thinks it's a chore- like studying yet another subject. I want to make sure he doesn't dread it.

Bring them to the library and let them choose their own books. There are so many genres and authors. If the book is about something they like, they will be more inclined to read and enjoy it. e..g. if your son likes dinosaurs, then you could bring him to the shelf at the library with books on dinosaurs.
