properties of real numbers (i.e. commutative, associative, distributive
properties…), be

able to add, subtract, multiply, and divide integers, fractions, and decimals,
convert from

one form of a number to another, understand and apply the order of operations
rules,

understand and simplify numerical exponential expressions, have a working

understanding of percents, understand the concepts of variables, expressions,
and

equations, solve simple linear equations in one variable, and use ratios and
proportions to

solve problems.

**Other Considerations**

• There should be an emphasis on the understanding of the underlying concepts.

• Communication, both oral and written, should be emphasized throughout the

course. Written solutions to problems should be expected and evaluated.

• Students should be allowed to use calculators and computers where
appropriate.*

• Classroom activities should be student-centered and involve
active/experiential

learning.*

• There should be an emphasis on problem-solving, estimation, and real-world

applications.*

• Alternative assessment should be incorporated into student evaluation.*

• At the end of each semester, a summary of the mathematics covered should occur

in which the relationships among concepts are emphasized. **Semester exams are
required of all students.**
