INTRODUCTION
One of the new middle grades curriculum projects, the Connected Mathematics Project (CMP), was funded to develop a complete mathematics curriculum with teacher support materials for the middle grades six, seven, and eight. This curriculum is structured to develop student’s knowledge and understanding of mathematics that is rich in connections-connections among the core ideas in mathematics and its applications. The CMP curriculum is organized around interesting problem settings-real situations, whimsical situations, or interesting mathematical situations. Students solve problems, and in so doing, they observe patterns and relationships; they conjecture, test, discuss, verbalize, and generalize these patterns and relationships.
