Building a System of Tens: Casebook

Participant Casebook is filled with classroom episodes that describe students' mathematical thinking.

Participants examine the actions and situations modeled by the four basic operations. The seminar begins with a view of young children's counting strategies as they encounter word problems, moves to an examination of the four basic operations on whole numbers, and revisits the operations in the context of rational numbers.

Even teachers learn by doing—Use Developing Mathematical Ideas to raise teacher comfort with math and student math achievement.

Each DMI Seminar models how math instruction should be delivered through practical examples teachers can follow in their own classroom.

Casebook
Each seminar is built around a casebook containing 25 to 30 classroom cases that include ideas expressed by students and teachers in their own words. These cases are grouped into seven chapters which track a particular mathematical theme from kindergarten through grade eight.
