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.
