Mathematics: Number and Quantity

In Number and Quantity, instructional time should focus on four critical areas: (1) extending the real number system, which includes developing rational exponents and relating rational numbers to irrational numbers through mathematical operations; (2) introducing units as a method of guiding students towards solving multi-step problems; (3) introducing the complex number system, showing how complex numbers can be evaluated using similar operations used with real numbers; (4) introducing the different properties of vectors and matrices and methods of modeling problems using those properties.
