The short answer is no, the Mortensen Math program, also known as Mortensen More Than Math, is not a complete curriculum.
The program focuses on mastering math skills in calculus, analytical geometry, trigonometry, geometry, algebra, and arithmetic, rather than fitting into a graded setting. Because of this students will be able to solve many math problems that are considered advanced for their age and grade.
It is a superb supplement to any curriculum as it simplifies and clarifies the concepts being taught.
Mortensen Math is a Gateway Program to the Higher Maths.
