Step-by-step strategies help students calculate complex formulas on calculators and in spreadsheets. A heavy conceptual emphasis is placed on understanding how the world of finance functions to develop personal financial management skills.

(!) – Honors designation is self-selected by students with teacher recommendation

(*) – Teacher recommendation required for taking concurrent math classes

(#) – or Probability/Statistics or Financial Algebra or Bridge to College Math

(%) – concurrent classes are two separate classes during the day

Bridge to College Math: Those students who take this course, and earn a B or better, will be exempt from taking the placement test and will go right into a college credit math course. It is designed for those students who took Algebra 2 and did not do well.

Financial Algebra: This course can replace an Algebra 2 credit. It does not count as a 4th year of math.

This course is designed for Seniors who have taken Algebra 2, and did not do well. For students who take this course and earn a B or better, they will be exempt from taking a college math placement test and will go directly into a college credit math course.

**IB MATHEMATICS STANDARD LEVEL A/B**

Credits: 0.5 credit / semester

Grade(s): 11, 12

Length of Course: Two Semesters

Prerequisite: Algebra 2

Graduation Requirement Satisfied: Math

This course caters for students who already possess knowledge of basic mathematical concepts, and who are equipped with the skills needed to apply simple mathematical techniques correctly. The majority of these students will expect to need a sound mathematical background as they prepare for future studies in subjects such as chemistry, economics, psychology and business administration. In IB Mathematics SL A/B students use functions as a mathematical basis to study real world phenomena, such as determining the distance between two planets as the angle of the Sun varies, or finding rates of exponential change in bacteria growth, or calculating average velocity. Major topics are the in depth study and writing of rational, logarithmic, exponential, polynomial, and power functions. Students develop mathematical models of periodic functions and right triangle problems. Students explore trigonometric and circular functions that include trigonometric function properties including their identities, with the use of parametric functions. The properties of combined sinusoids and three--‐dimensional vectors are also addressed. At Chief Sealth, IB Math SL A/B is the first year of the IB Math pathway. It is the prerequisite course for IB Math SL C/D. A senior taking IB Math SL A/B, and doing well, should place nicely into a college credit math course.

**IB MATHEMATICS STANDARD LEVEL C/D**
Credits: 0.5 credit / semester

Grade(s): 11, 12

Length of Course: Two Semesters

Prerequisite: IB Math SL A/B

Graduation Requirement Satisfied: Math

This course is a continuation of IB Mathematics SL A/B. Major topics are the study of vectors, differential and integral calculus, and statistics and probability. During IB Math SL C/D students will complete their internally assessed component which is 20% of the course. The internally assessed component, the exploration, offers students the opportunity for developing independence in their mathematical learning. Students are encouraged to take a considered approach to various mathematical activities and to explore different mathematical ideas. The exploration also allows students to work without the time constraints of a written examination and to develop the skills they need for communicating mathematical ideas. The exploration is internally assessed by the teacher and externally moderated by the IBO.

**IB MATH STUDIES STANDARD LEVEL**

This course is available only at standard level. It has an emphasis on applications of mathematics, and the largest section is on statistical techniques. It is designed for students with varied mathematical backgrounds and abilities. It offers students opportunities to learn important concepts and techniques and to gain an understanding of a wide variety of mathematical topics. It prepares students to be able to solve problems in a variety of settings, to develop more sophisticated mathematical reasoning and to enhance their critical thinking. Topics covered include: number and algebra; sets, logic, and probability; functions; geometry and trigonometry; statistics; introductory differential calculus; and financial mathematics.

**IB MATHEMATICS HIGHER LEVEL **
Credits: 0.5 credit / semester

Grade(s): 12

Length of Course: Two Semesters

Prerequisite: IB Math SL C/D

Graduation Requirement Satisfied: Math

This course caters to students with a good background in mathematics who are competent in a range of analytical and technical skills. The majority of these students will be expecting to include mathematics as a major component of their university studies, either as a subject in its own right or within courses such as physics, engineering and technology. Others may take this subject because they have a strong interest in mathematics and enjoy meeting its challenges and engaging with its problems.

The course syllabus for Mathematics HL consists of seven topics: algebra, functions and equations, circular functions and trigonometry, matrices, vectors, statistics and probability, and calculus.

In addition, there are four optional topics of study ("Options"), one of which must be selected by the school.

These four options:

- statistics and probability

- sets, relations, and groups

- calculus

- discrete mathematics

During IB Math HL students will complete their internally assessed component which is 20% of the course. The internally assessed component, the exploration, offers students the opportunity for developing independence in their mathematical learning. Students are encouraged to take a considered approach to various mathematical activities and to explore different mathematical ideas. The exploration also allows students to work without the time constraints of a written examination and to develop the skills they need for communicating mathematical ideas. The exploration is internally assessed by the teacher and externally moderated by the IBO.
