Please Note: All courses will require a minimum of two students to run. Families will be informed by May 15 if we are unable to run a particular course.
Grades 9-10 Mini Module Session 1 (July 7 - July 25, 2025)
The summer algebra 1 course at CSW is designed for students looking to strengthen their algebra skills before their school year courses begin. This distilled version of Algebra 1 focuses on the key topics needed to excel in the future math curriculum, including work with variables, exponents, and radicals, functions and transformations, linear functions and modeling, and quadratic functions and equations.
Successful completion of summer Algebra 1 allows students to place out of Algebra 1 and into Geometry or Algebra 2 for the subsequent school year. Students, especially incoming students, are also invited to take Algebra 1 before enrolling in Algebra 2 even if their placement does not necessarily indicate a need, in order to strengthen their skills and confidence in math, gain familiarity with CSW math curricula, get to know CSW teachers and fellow students, and enjoy enhancing their math abilities in a focused, fun, and non-grade-centric environment.
Geometry
Grades 10-11 Mini Module Session 2 (July 28 - August 15, 2025)
The summer Geometry course at CSW is designed for rising 10th or 11th students looking to complete geometry before enrolling in Algebra 2 and beyond during their subsequent school years. This shortened version of geometry focuses on lines and angles, symmetry and proof, circles, areas, and volumes, and right triangle trigonometry.
Successful completion of summer Geometry allows students to place out of Geometry and into Algebra 2 and potentially precalculus courses for the subsequent school year. Incoming students are also invited to take summer geometry even if their placement does not necessarily indicate a need, in order to strengthen their skills and confidence in geometry, gain familiarity with CSW math curricula, get to know CSW teachers and fellow students, and enjoy doing math in a focused, fun, and non-grade-centric environment.
