Algebra has always been a watershed for pupils learning mathematics. Nevertheless pupils bring to school all the necessary natural powers for thinking algebraically, including organizing, classifying and generalizing. Developing Thinking in Algebra has been constructed in a way that will enable teachers and their support staff to experience and to teach algebraic thinking to pupils aged 7-16. By integrating pedagogy and subject knowledge through experiencing a variety of tasks for learners, readers of this book will see how to engage all learners in successfully thinking algebraically.
