I have just finished my review of CAMS & STAMS books from Curriculum Associates ... It is a series of assessment books, student worktexts, and teacher guides for struggling students that presents each math topic in a highly scaffolded manner.   These books are supplemental  to any basal math curriculum, and have been specifically designed to support struggling students . Each level consists of:    a student book (consumable worktext) with  instruction and exercises. This is the heart of the program, and always  covers the most important topics of the grade level, as given in the  NCTM Focal Points and Connections.  A test booklet, which contains a pretest, a  postest, and four "benchmark" tests. The benchmark tests are to be used  to monitor student progress throughout the  year.  A very detailed teacher guide for the student text, and another, much thinner teacher guide for the assessment booklet.   Read the review!
