Algebra Extended 10: Algebra Extended 10 is designed to follow Algebra Extended 9. This course will complete the content that began in the Algebra Extended 9 curriculum and ends in June with the NYS Algebra Regents Exam. We do not use a specific textbook in Algebra Extended 10. This course is being taught through the use of power points, interactive websites and various technologies. Teacher collaboration and creativity will be effectively used throughout the year to communicate concepts and encourage critical thinking.
