This is an unusual math book: it is meant to be read aloud by a tutor and a student. It consists primarily of explanations, in words, of important math concepts. Reading comprehension questions rather than math problems check whether the reader is understanding. The learner who uses it practices reading comprehension in the subject area of math. This book starts with very basic ideas such as place value, sets, and addition, and moves through concepts of algebra. The format of small sections with a "comprehension probe" after each is custom made for tutoring, but also suited for the individual reader.
