A tried and true way for children to learn to enjoy reading is to read the daily comics. Some of the benefits are developing a more sophisticated sense of humor, following a continuing storyline over days or weeks, and exposure to many writing and illustration styles. The children will naturally skip over the boring adult oriented strips, and find their favorites. Reading small bites daily (during breakfast?) helps to instill the reading habit.
A very informal survey of your children tells me that many
of you get a daily newspaper. How about
casually putting the comics on the table tomorrow?
No newspaper? Try http://www.gocomics.com/explore/comics where you can discover new comic strips. Just keep a parental eye out, just as you would with any online resource.
