By Catherine Twomey Fosnot and Bill Jacob / Heinemann 

Provides a landscape of learning that helps teachers recognize, support, and celebrate their students' capacity to structure their worlds algebraically. The book identifies the models, contexts, and landmarks that facilitate algebraic thinking in young students and provides insightful and practical methods for teachers, math supervisors, and curriculum coordinators. Uses classroom vignettes to illustrate the investigations and mini-lessons students engage in as they build their mathematical knowledge.

"When children are given the chance to structure number and operation in their own way, they can make sense of algebra not as a funny set of rules that mixes up letters and numbers but as a language for describing the structure and relationships they uncover." -Catherine Twomey Fosnot and Bill Jacob
