String Explorer is a synthesis of the best pedagogy of the past aimed at the future and forged from the authors' combined total of more than 75 years in the classroom. Designed with the teacher in mind, the series includes all materials needed for the classroom with cross-references between them so they are easy to access. Designed with the student in mind, String Explorer has the fun and information-packed look of a web page. Characters lead the way through the book and point out all the information that a teacher or student will need to know for each unit! Skills are presented sequentially and never more than one at a time.
