Okay, let's start simple. Talk to each boy individually and ask him why he isn't reading ... offer to give them an easier book ... spend some time getting to know them ... it's easier to ignore your requests if they don't have a relationship with you ... next, when they aren't reading, stand silently by their chair, smile, tap their book, see if this prompt works ... if you are making no progress after a week, and you think the whole class is ready for it, go to the Practice Cards (see free download) ... incidentally, we are not big fans of silent reading. Try the Crazy Professor Reading Game (free download) and you'll probably solve all your problems quickly.
