*Pre-Algebra* teaches 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.
