Course Description
From the CTY Online Catalog:
CTY's Problem Solving and Enrichment Math 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 software provided by Riverdeep, these courses demonstrate how mathematical issues arise out of real-life situations. Concepts are assessed through challenging quizzes and module tests. With the guidance of their instructors, students typically select enrichment or supplementary math courses of the appropriate level in between their accelerated courses to ensure a solid foundation and mastery of math concepts at each level.
Problem Solving in Pre-algebra prepares students for a more formal study of mathematics in middle school. It is appropriate for students who have a good understanding of concepts in pre-algebra, but who wish to enrich their skills through interesting word problems. Students continue the study of numbers and their operations by exploring:
ratios proportions algebraic concepts radicals and exponents geometry statistics probability Students apply what they have learned to solve sets of questions at varying levels of difficulty. Students are also invited to participate and ask questions in an open Help Room guided by instructors.
This course provides an excellent foundation for students who will be advancing into Honors Algebra I.
