Math Course Descriptions

ALGEBRA 1
This is the first math course required of a Core 40 diploma. This class extends the algebra studied in middle school. Students will learn to solve linear and quadratic equations. Students will graph and interpret graphs of lines and parabolas. A scientific (not graphing) calculator is required.

Geometry  A Deductive Approach
This course takes geometry concepts studied in middle school to a higher level. Topics include angles, lines, planes, and shapes. Students will also study 3dimensional solids and right triangle trigonometry. There is a strong emphasis on reasoning as students prove geometric properties. Students will use geometry software and spreadsheets. Note: May be taken concurrently with 11303 Algebra 2 with teacher recommendation or department chair permission, however, students interested in taking Algebra 2 and Geometry concurrently are encouraged to take the block class (11312 and 11313).

Geometry/Algebra 2
This course provides an option for students who are “doubling up” in Geometry and Algebra 2. Geometry is completed during the first semester and Algebra 2 is completed during the second semester. This class takes two periods each semester. The reason for “doubling up” is to prepare students beginning with Algebra 1 freshman year to take an AP or dual credit math elective dng their senior year. This plan requires strong math skills and interest in mathematics. It also requires good study skills. The curriculum is identical to 11302 Geometry and 11303 Algebra 2. A TI83+ or TI84 graphing calculator will be required for second semester. (This course may bne taken by freshman who had Algebra 1 in 8th grade with department chair approval.)

Geometry  Honors
This is a challenging geometry course. It is enriched and faster paced than the other geometry courses. A strong emphasis will be placed on student inquiry and reasoning. Students will tackle challenging problems and complete indepth investigations. Geometric computer software will be used extensively and spreadsheets will be incorporated as a problemsolving tool.

Algebra 2A
This course adds to the algebra learned in Algebra 1. Topics include absolute value, quadratic, polynomial, logarithmic and exponential functions. The course also covers algebraic fractions, sequences and series. Students apply the math to real situations. Communication and reasoning are important. This course is more theoretical and abstract in its approach than 11104. This theory and abstraction is important for students planning to take Precalculus. A TI83+ or TI 84 graphing calculator is required.

Algebra 2  Honors
This course adds to the algebra learned in Algebra 1. Topics include absolute value, quadratic, polynomial, logarithmic and exponential functions. The course also covers algebraic fractions, sequences and series. Students apply the math to real situations. This class is faster paced and more challenging than the other Algebra 2 options. Communication and reasoning are important. A TI83+ or TI 84 graphing calculator is required.

Precalculus
This course is for students who will be taking calculus in high school or college. Precalculus is especially appropriate for students planning to major in a STEM field (Science, Technology, Engineering, or Math). The course centers on the study of functions. This includes polynomial and rational functions. It also includes exponential, logarithmic, and trigonometric functions. To emphasize realworld connections, data analysis will be incorporated throughout the course. Verbal and written communication will be emphasized along with mathematical reasoning, and problem solving. This course includes all of the content of the one semester Trigonometry course, along with additional standards. A TI83+ and TI84 graphing calculator is required

Precalculus  Honors
This course is for students who will be taking AP Calculus. Pre calculus is especially appropriate for students planning to major in mathematics, engineering, computer science or science related fields. The course centers on the study of functions. This includes polynomial and rational functions. It also includes exponential, logarithmic, and trigonometric functions. Parametric equations, polar coordinate equations, and sequences, and series are also included. To emphasize realworld connections, data analysis will be incorporated throughout the course. Verbal and written communication will be emphasized along with mathematical reasoning, and problem solving. A TI83+ and TI84 graphing calculator is required. This course may be offered for 6 semester hours of credit as M136 College Algebra and M137 Trigonometry with Analytic Geometry through Ivy Tech Community College.

College & Career Ready Bridge: Math
This course will reinforce mathematics procedures and concepts from algebra, geometry , and statistics in realworld contexts that deepen students’ understandings. This course emphasizes understanding of mathematics concepts rather than just memorizing procedures. Math Ready students learn the context behind procedures and understand why to use a certain formula or method to solve a problem. By engaging students in realworld applications, Math Ready develops critical thinking skills that students will use in college and their careers.
Note that Math Ready is not designed to prepare students for advanced mathematics in STEM majors. This course covers some trigonometry topics, but does not satisfy the trigonometry requirement for admission into some colleges and universities.

Trigonometry
This course extends the study of trigonometry that was begun in Geometry. The study of trigonometry is extended to triangles beyond right triangles and to circular functions. The graphs of all six trigonometric functions and their inverses will be included. This course prepares students for college placement tests and postsecondary study in any technical field. Technology is an integral part of this course and a TI83+ graphing calculator will be required. The topics in this one semester class are also included in the second semester of Precalculus. A TI83+ and TI84 graphing calculator is required.
