Doing mathematics
In general, a mathematical approach involves defining a problem through conjecturing in an established mathematical area. Conjecturing may be supported by technology, by compelling ideas based on past work, computation, or pattern exploration. ( Teachers for a New Era, 2003)
Doing mathematics
Mathematics involves representing a mathematical concept concretely; a single concept can have multiple representations. One of the beauties of mathematics as a whole is the interplay between various areas of the subject. A particular way of representing a problem may lead to an especially efficient or enlightening result.

Capstone Course - MSU Senior Math Majors :
• Deepen understanding of the mathematics needed for teaching in secondary schools. • Prepare students to 1. describe connections in mathematics; 2. figure things out on their own.
High school math from an advanced perspective
• Analyses of alternative definitions, language and approaches to mathematical ideas; • Extensions and generalizations of familiar theorems; • Discussions of historical contexts in which concepts arose and evolved; • Applications of the mathematics in a variety of settings;
High school math from an advanced perspective
• Demonstrations of alternate ways of approaching problems, with and without technology; • Discussions of relations between topics studied in this course and contemporary high school curricula.
Habits of mind: Mathematics should make sense
• Know that all mathematics is not equal • Understand that mathematics can be done different ways • Be willing to work hard on a challenging problem for a long time • Recognize that mathematics is about how mathematical results are obtained not how they are presented
Mathematically confident enough to take risks • Using technology • Asking for explanations • Doing problems with students • Trying something new • Celebrating mistakes
