Teachers are the key to improving mathematics education.
Few would disagree. Regardless of the curriculum or the assessment process in a school district, the person in charge of adapting materials for a particular classroom and student is the teacher. It is through teachers' efforts that students have opportunities to learn mathematics. The goals of new curriculum materials have to be reachable by caring teachers. When teachers examine new curricula, they need to be able to see how to move from their current practice to where the new materials are heading.
