COURSE DESCRIPTION:
The focus of the first half of the course is on improving problem solving and on applying strategies to
answer the types of test questions students are likely to encounter such as multiple choice, grid response,
free form, and open-ended. The remainder of the course, through project work, will cover a variety of

Contemporary technology will be used to assist in problem solving.

MISSION RELATED GOALS:
This class will provide the student with a variety of opportunities to demonstrate academic excellence
and intellectual curiosity by communicating effectively, solving complex problems, and working with
others toward a common goal.

Students will be afforded opportunities to apply mathematical concepts to real-world applications. A
variety of teaching methods will be used to foster an environment that promotes self-confidence and
respect for others throughout the school and global community.

CURRICULUM FRAMEWORK LEARNING STANDARDS:
I. Identify and use the properties of operations on real numbers, including the associative,
commutative, and distributive properties. (10.N.1)
II. Simplify numerical expressions, including those involving positive integer exponents or the
absolute value; apply such simplifications in the solution of problems. (10.N.2)
III. Describe, complete, extend, analyze, and create a wide variety of patterns.
(10.P.1)
IV. Demonstrate an understanding of the relationship between various representations of a line.
Determine a line’s slope and x- and y-intercepts from its graph or from a linear equation that
represents the line. Find a linear equation describing a line from a graph or a geometric
description of the line, e.g., by using the “point-slope” or “slope y-intercept” formulas. Explain
the significance of a positive, negative, zero, or undefined slope. (10.P.2)
V. Add, subtract, and multiply polynomials. Divide polynomials by monomials. (10.P.3)
VI. Solve equations and inequalities and apply to the solution of problems. (10.P.6)
VII. Solve everyday problems that can be modeled using linear, reciprocal, quadratic, or exponential
functions. (10.P.7)
VIII. Recognize and solve problems involving angles formed by transversals of coplanar lines.
Recognize and solve problems associated with radii and chords.
(10.G.3)
IX. Solve simple triangle problems using the triangle angle sum property and/or the Pythagorean
Theorem. (10.G.5)
X. Draw the results, and interpret transformations on figures in the coordinate plane.
(10.G.9)
XI. Demonstrate the ability to visualize solid objects. (10.G.10)
XII. Calculate perimeter, circumference, and area of common geometric figures such as
parallelograms, trapezoids, circles, and triangles. (10.M.1)
XIII. Given the formula, find the lateral area, surface area, and volume of prisms and spheres.
(10.M.2)
XIV. Select, create, and interpret an appropriate graphical representation (e.g., scatterplot, table, stemand-
leaf plots, box-and-whisker plots, circle graph, line graph, and line plot) for a set of data and
use appropriate statistics (e.g., mean, median, range, and mode) to communicate information
about the data. Use these notions to compare different sets of data. (10.D.1)
XV. Solve a variety of equations and inequalities using algebraic, graphical, and numerical methods,
including the quadratic formula; use technology where appropriate. Include polynomial,
exponential, logarithmic, and trigonometric functions; expressions involving absolute values;
trigonometric relations; and simple rational expressions. (12.P.8)
XVI. Describe a set of frequency distribution data by spread (i.e., variance and standard deviation),
skewness, symmetry, number of modes, or other characteristics. Use these concepts in everyday
applications. (12.D.5)
XVII. Use combinatorics (e.g., “fundamental counting principle,” permutations, and combinations) to
solve problems, in particular, to compute probabilities of compound events. Use technology as
appropriate. (12.D.6)
XVIII. Define the sine, cosine, and tangent of an acute angle. Apply to the solution of problems.
(12.G.1)
