Regents Common Core Algebra

Welcome to Common Core Algebra with Mr. Scapellati!

Common Core Algebra is a rigorous high school level course which concludes with students sitting for the administration of the Algebra 1 Regents Examination in June.  Placement in this course is based on the demonstration of strong math skills/potential in both sixth and seventh grades.  Successful completion of this course results in appropriate high school credit.

To the incoming Math 9 students:
