Just that really! As my son's reading improves they are sending him one phonic and one normal reading book (mostly but not exclusively ORT). With the second type - do you read it first to them or what? The Biff, Chip and Kipper non-phonic ones seem to contain a lot of words that aren't in the top 100 most frequent and aren't decodable which I'm guessing is on purpose. So far he's figured it out by context or by the pattern of the book - is this how it goes?
