##### Algebra I

(two semester course)

Algebra I is the second theoretical course in Classic Math School’s Enrichment Program, and is intended for students from 6th to 9th grade. This course prerequisites include the fluency in solving one-variable linear equations. The scope and depth of the course may vary significantly depending on the actual students’ level and duration of the course.

This course generally covers the same topic area as most of Algebra I courses around the country, but with conceptual approach and significant depth. It also covers some topics from Algebra II.

The key elements of this Algebra I course:

Absolute value equations and inequalities.

Systems of linear equations and inequalities with geometric interpretation involving slope concept.

Quadratic equations.

Concepts introduction and problem solving form an integral part of each class session. Students learn extensively from and by examples, and through problem discussions. A variety of instructional methods are used to enhance students' problem-solving abilities. Students tackle many complicated problems using inductive and deductive reasoning approaches.

The topics and problems that are studied in Algebra I course may include:
