Snap a photo of a page and project onto screen/whiteboard and then Crack the Comprehension. Or simply choose a page as your 'snap shot' of the book, and work with it inside a clear plastic folder. 
Use this as a quick 5 - 15 minute activity (ideally daily) either with the whole class or in pairs. We recommend having Spelling Cloud Mats handy to check new phoneme-grapheme combinations.
