Upper School Math Teacher (Lone Tree, CO)
Job Type

Ascent Classical Academy of Douglas County seeks upper school teachers for its K-12 Lone Tree campus in the south Denver metropolitan area.

At Ascent Classical Academies, teachers create their own lessons within the framework set by our content-rich curriculum, in collaboration with colleagues and in partnership with Hillsdale College's Barney Charter School Initiative. Teachers are dedicated to mastering the key elements of their instruction and to the intellectual and moral betterment of their students.  Ascent Classical Academies teachers take seriously their own moral and intellectual improvement, as part of a hard-working, supportive, and excellence-driven culture.  


The discipline of mathematics strips away all subjectivity regarding reality. Through the study of mathematics, the learner confronts the abstract and must engage in the uniquely human capacity for purely rational thought. Logic and reason in every discipline owe their structure to mathematical principles. In discovering and mastering these principles, the learner’s mind is shaped into a powerful tool of reason. Robust training in mathematics prepares the student to test possible truths against established principles, and even discover new truths by building on the work of those who have come before.


In the grammar stage, the learner is taught the bedrock ideas of abstract, numerical thinking through definitions, operations, and rules of arithmetic. In the logic stage, the learner discovers the major structures - algebraic manipulation, geometric reasoning, and the generation and use of formulae - which can be built from, and upon, these bedrock ideas. In the rhetoric stage the abstraction intensifies with disciplines such as trigonometry and calculus. Here, the learner applies the previously established logical structures to new and unfamiliar objects, examines the implications of changing a particular rule, and, through creative questioning, discovers new proofs that provide complex frameworks which illuminate and enliven the cosmos in which we live.
