Side by side is the book that the teachers at the Literacy Center loved. It is for beginners through (I don`t know, maybe low intermediate). Students who tested after learning with Side by Side showed gains (improvements) in their scores. Many of our readers are too advanced to benefit from this book, but for the beginners, it is a good choice.
