Mathematics Department Philosophy

The Justin-Siena Mathematics curriculum is designed to enhance reasoning, problem-solving, deductive and logical thinking, and the application of mathematics to practical situations.  Mathematics courses emphasize individual and collaborative group work in which discussion, problem-formulation, and written problem-solving are core learning strategies.  The curriculum and instruction ask students to “interleave” their practice, so that students repeatedly re-visit concepts applied in new situations, leading to increasingly deeper and more sophisticated understanding.

Initial Mathematics Placement

Ninth graders are placed in appropriate mathematics courses (typically Algebra I, Geometry, Honors Geometry, Algebra II, or Honors Algebra II) based on prior coursework, eighth grade mathematics grades, teacher recommendations, placement test (PSAT 8/9) scores, and results of the Justin-Siena Math Challenge Test.
