Activity set-up/instructions or description of technique:
Yes, we read to the children often. Many times they were put to bed with a book, even before they could read (by themselves). But, make the reading time itself the reward. We do not really make a point of rewarding reading, rather they "get" to read for a certain time before lights out!
