A new curriculum, and then a book based upon that, always seeks evaluation. The book should not only be attractive and interesting, but also upto the mark with the age level of students, appropriateness of content, relevance, utility, etc. Every new book should be thoroughly evaluated before it is given a place in list of textbook or suggestive readings or after introducing in a course. An exercise for evaluating a textbook has been presented in the current book. For this purpose, a textbook for class IX Mathematics, introduced in schools, has been selected. The study goes through explaining various aspects of evaluating the book. It makes an effort to see the book through the lenses of teachers as well as students. The book looks forward to place teachers not just as mere followers of the book introduced, but as reflectors, too, upon various aspects of the book.
