Pre-Algebra is designed to give those students who need reinforcement of their basic math skills the chance to work on these skills as well as develop their algebra skills. These skills include: order of operations, using negative and positive numbers, solving equations, simplifying expressions, percents, ratios, finding perimeter, area and volume, and analyzing data. Concepts from arithmetic, geometry and algebra are integrated throughout the course. Most concepts are presented as tools to solve problems or to make mathematical models of real situations. There is an emphasis on communicating mathematics through writing as well as diagrams and computations.
