Computer Science is a science of abstraction -creating the right model for a problem and devising the appropriate mechanizable techniques to solve it.
– A. Aho and J. Ullman

This course will prepare our elementary students (Grades 3-6) for the Elementary Division contest in the American Computer Science League. The goal is to teach algorithmic programming, problem solving using computers and prepare students for ACSL and programming competitions in general.
Each ACSL elementary contest for basic knowledge of CS theory. Topics include Number Systems, Boolean Algebra, and Graph. This course will also introduce concepts on strings, arrays, etc for preparing them for future coding programs.
