In the 7B books, students will see great growth in mathematical maturity. 

Overview

Students will work through a classical axiomatic approach to geometry, beginning with basic axioms and definitions, moving on to a thorough examination of parallel lines, triangle congruence theorems, and the basics of Euclidean constructions. Emphasis is placed on clear, logical thinking and writing. In algebra, students learn to solve linear equations, as well as equations that reduce to linear ones: reducible quadratics, the absolute value of linear and factored quadratics. 

The modeling and applications are more advanced, and students learn methods for clearly organizing their thoughts and work as they solve word problems on motion, work, mixtures and alloys, along with basic finance. The year closes with review, giving students a reminder just how much they have grown.
