## Algebra 1

(two semester course)

Algebra I course is part of the Classic Math School Enrichment Program. Students meet twice a week for a two-hour session. Each of two semesters is comprised of 15 sessions. Students complete 45-60 minutes homework each week. This course generally covers the same topic area as most of Algebra I courses around the country, but with enhanced depth and emphasis on conceptual approach.

Concepts introduction and problem solving form an integral part of each class session. Students learn extensively from and by examples, and a variety of instructional methods are used to enhance students' problem-solving abilities. Students tackle many complicated problems using inductive and deductive reasoning approaches. Some of the topics and problems that are studied in this course include:
