Pre-Algebra integrates text, DVD, and manipulatives to teach all basic Pre-Algebra concepts. These include negative numbers, exponents, factoring, and ratios. The student is taught basic rules of solving equations using the associative, commutative and other properties. Simple operations with polynomials are demonstrated with place- value blocks for conceptual understanding before being taught conventionally. Geometry concepts include surface area, volume, and the Pythagorean theorem.
