With Liping Ma

It is common in the United States to view mathematics, particularly elementary mathematics, as a collection of rules, "shopkeeper arithmetic," or "basic skills." In contrast, a solid school mathematics (*Knowing and Teaching Elementary Mathematics*, Liping Ma, Lawrence Erlbaum Associates, 1999, pp. 146, 149) has breadth and depth and provides a foundation for future learning of mathematics. In this talk we discuss what such a school mathematics might look like, what factors have militated against its development in the United States, and how we might foster the development of a solid school mathematics.
