Mathematics

Full year, ninth grade

Students develop skills and concepts so as to learn how to solve problems using variables. Learning occurs through discussion, exploration, and group work, with the teacher acting as a guide. Topics include real, rational, and irrational numbers; solving linear and quadratic equations; graphing linear and quadratic equations; systems of linear equations; factoring polynomials; properties of exponents; properties of radicals; and simplifying rational expressions. There is an emphasis on solving problems algebraically, as well as through other methods including modeling and graphing. Developing communication skills is essential to the progression of the students’ mathematical competence.

First semester, ninth, or tenth grade

Students use an inferential approach to problem solving to build a foundation in Euclidean geometry. Through investigations of parallel lines, triangles, quadrilaterals, and circles, students make conjectures about the nature of these shapes and search out evidence to support their ideas. Students use both physical representations of diagrams and dynamic geometric software to explore the relationships present in geometric figures. The distinction between conjecture and proof and the limitations of inferential reasoning are given particular emphasis. Other course topics include conditional logic, right triangle trigonometry, and the extension of geometric relationships to three-dimensional figures. Prerequisite: Algebra I or equivalent

First intensive or second semester
Ninth, tenth or eleventh grade

This course is an introduction to formal reasoning, logic, and proof. Students examine how Euclid’s postulates are the basis of an axiomatic structure for plane geometry.

Intro to Statistics develops students’ potential to quantify and interpret what they observe; collecting, representing, analyzing, and modeling with data are activities of major importance in contemporary society. This statistics course emphasizes that learning to interpret data correctly is a means to developing increased awareness of social, political, and scientific issues. Students learn to create unbiased surveys and experiments, detect bias in other surveys, describe data objectively with graphs table, and numerical statistics; determine correlation between variables and understand the concept of a statistically significant result.

In the intensive model of Intro to Statistics, students look outside the Statistics textbook and inside the city of Seattle (and beyond) to learn how to become a generator, user, and interpreter of information from a statistical perspective.

Prerequisite: Algebra IIB (or equivalent).
