**Algebra II**

**Advanced Algebra through Functions**

**(two semester course)**

Algebra II is a fourth theoretical course in Classic Math School’s Enrichment Program, and intended for students from 8th to 10th grade. The course prerequisites include fluency in making and solving linear and quadratic equations and inequalities (Algebra I).

The key elements of this Algebra II course:

Exploring functions’ behavior within the scope of elementary math.

Graphing functions. Translating graphs.

Using functions and equations as models for the word problems.

Concepts introduction, including proofs of theorems and derivation of formulas, as well as problem solving formed 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. Some of the topics and problems that were studied in this course include:

Relations and Functions

Domain and Range.
