Algebra 2Course description
This is a resubmission of MA44 which was deferred due to “need more information.” It is being submitted by Michael Drobitsky and Kathy English from the Mesa Public School district. If you have any questions or need any more information please contact Michael at 480-773-1506 or [email protected]
Thank you for your time and consideration.
This course will fulfill the fourth year math requirement for graduation; has an Algebra 2 prerequisite and will count as a math credit toward university admission and towards a scholastic diploma for Mesa Public Schools. It is designed around the structure of STEM practices to teach the practical application of math in our society. We will be using an innovative; non-traditional; “hands-on” methodology in our curriculum. The justification for the implementation of this course is to provide college bound students an opportunity to explore mathematics as it is utilized in real world situations.

A need for this class was seen through the lens of the Mathematical Practices of the Common Core. Students in the traditional mathematics class are seldom given the time and opportunity to see the connections between math in action and the world in which they live.
