Algebra I

 

Algebra I objectives provide the gateway to all higher mathematics courses.  An emphasis on conceptual development and multiple representations will be used to draw generalizations and to serve as a tool for solving real-world problems.  Algeblocks may be used to bridge the gap from the concrete to the abstract.  Available technology such as calculators, computers, and interactive utilities are to be used as tools to enhance learning.

 

The West Virginia Standards for 21st Century Learning include the following components:  21st Century Content Standards and Objectives and 21st Century Learning Skills and Technology Tools. 

 

All West Virginia teachers are responsible for classroom instruction that integrates learning skills, technology tools and content standards and objectives.
