Course Description

Description

CTY's Problem Solving courses sharpen investigative skills, broaden mathematical understanding of concepts, and enhance reasoning skills. Designed around performance objectives that reflect national and state mathematical standards and drawing on video lectures provided by Thinkwell, these courses demonstrate how mathematical issues arise out of real-life situations. Concepts are assessed through challenging quizzes and chapter tests. 

In Problem Solving in Geometry, students apply geometric concepts to solve sets of word problems at varying levels of difficulty. This course provides an excellent foundation for students who will be advancing into Honors Geometry or Honors Algebra II.  Students will have their understanding checked with graded assessments, which include quizzes, homework, tests, and cumulative midterm and final exams.

Upon successful completion of this course, a student will be able to understand definitions and theorems as well as solve problems related to:

  • Points, Lines, Planes, and Angles
  • Angle Relationships in Polygons 
  • Triangle Congruence and Similarity
  • The Pythagorean Theorem and Its Converse
  • Properties of Quadrilaterals
  • Areas of Plane Figures
  • Volumes and Surface Areas of Solids
