The course begins with piecewise functions to allow students the opportunity to review functions studied during previous courses. Students should be familiar with identifying key features. A focus, for piecewise functions, is on the domain for the different pieces of the function. Consider exposing students to absolute value functions as a type of piecewise function prior to the more extensive study in the following outcomes. Students have been using function notation since Math 1. Include more complex use of function notation such as 𝑓(𝑎) + 2𝑓(𝑏) where 𝑎 and 𝑏 belong to different parts of the domain. Students should be able to graph in simple cases and use technology, such as Desmos, in more complex cases.

Absolute value is a new function for students. Consider reviewing the definition of absolute value (developed in middle grades) as students identify the key features of the function. The intent is for students to revisit the transformations from Math 2 and add the new transformation 𝑓(𝑘𝑥) with a focus on absolute value functions. Revisit the transformations in the polynomial and trigonometric modules. Students should describe the transformations’ effect on the graph and the table. Continue reinforcing the key features. Students should be flexible in describing the transformations given a function 𝑓(𝑥) where 𝑓(𝑥) is not limited to the parent function.

Students studied exponential functions in Math 1. The extension, in Math 3, is for students to be able to rewrite the growth/decay factor and interpret what it means in context. Consider reviewing the power to a power exponent rule for this outcome. A-REI.11 includes solving a variety of one variable equations such as, 4(1.23)3 = 7(2.5)3, using graphs and tables. Students should understand logarithms are a way to rewrite numbers with the same base. They use that understanding to solve exponential equations without the use of the laws of logarithms. For further explanation refer to the Math 3 Math Resource for Instruction document.

Outcome 5: I can identify and represent the inverse of a function. (2 days) a. I can create a table and a graph of an inverse given any

representation of a function.F-BF.4a,c b. I can determine if an inverse function exists from a graph,

table, or equation.F-BF.4b c. I can describe domains of a function where an inverse function

Students should reason with a variety of function types, both traditional and non-traditional. These functions can be presented as graphs and tables. Students should also be able to restrict the domain of a function in order to describe when an inverse function exists. Students should be able to use and interpret interval notation, inequalities, and words to describe restricted domains. (Interval notation was used in Math 2.)

Outcome 6: I can write the inverse function of a given function. (3 days) a. I can write the inverse function of a linear function using

algebraic reasoning.F-BF.4c b. I can write the inverse function of an exponential function

The outcome is specific to the types of functions the F-BF.4 standard references. Students will need to rewrite quadratics by completing the square in order to write the inverse function of a quadratic function. The process of completing the square was studied in Math 2. As an honors extension, consider having students find the inverse of one or both types of functions. The intent of this extension is to strengthen students algebraic skills.

This module approaches the study of polynomials by first studying the key features and characteristics of polynomial functions followed by a deeper study with the algebraic concepts. The outcome begins with students graphing and identifying key features of polynomial functions. Next, students identify the key features (intercepts and end behavior) from factored form and sketch the polynomial graph using these key features. (Sketches may lack some precision). Students reverse the process by using the key features to write the factored form of the polynomial function. Key features can be given as a graph, description, or ordered pairs. Creating the polynomial functions is an opportunity to connect back to the transformation 𝑘𝑓(𝑥).

Outcome 8: I can reason with multiple representations to solve polynomial equations. (6 days) a. I can factor a polynomial function with degree of 3 or less.A-

SSE.2 b. I can divide a polynomial expression and determine if the

Factoring quadratics is a focus in Math 1. In Math 3, students should be able to factor special cases such as a difference or sum of cubes, factoring with a GCF, and factor by grouping. Consider dividing polynomials using the area model. Students should use any method to solve polynomial equations. A-REI.11 includes all function types and should be reviewed after Module C with rational functions and trigonometric functions. It is not solving a system of equations. These solutions should only be the x-coordinate of the intersecting functions.

Students use geometry and algebra concepts to model and solve problems. Geometry concepts include perimeter, area, volume. Contextual situations include density, design and optimization.

Outcome 9: I can use perimeter, area and volume formulas to solve problems. ( 3 days) a. I can describe the two-dimensional cross-sections of three-

dimensional objects.G-GMD.4 b. I can describe three-dimensional objects generated by

rotations of two-dimensional objects.G-GMD.4 c. I can calculate the volume of a prism, pyramid, cylinder, cone

or sphere.G-GMD.3 d. I can determine the value of a specific measurement when

given the volume of a prism, pyramid, cylinder, cone or sphere and all other necessary measurements.G-GMD.3

The outcome begins with cross sections and rotations which provides the opportunity to define a prism, pyramid, cylinder, cone, and sphere. Students should explore all types of cross sections and generalize for cross sections that are parallel to the base and those that are perpendicular to the base. Students studied volume in 8th grade. Review area formulas for figures that can be possible bases of a prism or pyramid. This includes the area of a circle, triangle and parallelogram. Students should know the formulas in this outcome, as it is unclear whether the formulas are provided for them on the EOC. Consider having students distinguish between figures that are compositions of two or more figures added together and those that are subtracted. See examples below.

Outcome 10: I can apply geometric concepts to solve problems. (4 days) a. I can apply concepts of density based on area or volume to

solve problems.G-MG.1 b. I can create functions to model relationships within geometric

figures. G-MG.1 c. I can use geometric and algebraic concepts to solve design

problems.G-MG.1 d. I can use geometric and algebraic concepts to solve

optimization problems.G-MG.1 e. I can define the points of concurrency of triangles (centroid,

incenter, and circumcenter) and identify their properties.G-CO.10 f. Honors: I can design and describe measurements of a 3D figure

Students may be familiar with density, from science, where density is mass per volume (ex. gold’s density is 19.32 g/cm3). Student understanding of density should extend to population density (ex. Asheville’s population density in 2016 was 1,948 people/mi2). Students should be flexible when solving density problems. When given the density, and either the area or the volume, students can solve for the unknown quantity. Students should attend to precision with units and use the units as a way to understand the problem and guide their solution. For examples for design and optimization problems refer to the Math 3 Math Resource for Instruction document. Recognize that points of concurrency are not directly related to the other standards in this module. These concepts are included here because the properties of points of concurrency can be emphasized to solve problems.

In the figure to the left, the hemisphere and cone are added together.

In this figure, the cone has been removed/ subtracted out of the cube.

This module approaches the study of rational functions by first studying the key features (intercepts, increasing/decreasing, end behavior, horizontal/vertical asymptotes, and discontinuities) and characteristics of rational functions followed by a deeper study with the algebraic concepts. At a minimum, students should be able to analyze a rational function for a given value of 𝑥 and determine if there is a discontinuity. Students should have an opportunity to discuss the difference between an asymptote and a hole. Rewriting the rational function allows students to recognize discontinuities and their relationship to functions.

Outcome 12: I can operate with rational expressions. (3 days) a. I can add or subtract two rational expressions (limited to

denominators that are linear expressions).A-APR.7a b. I can multiply two rational expressions.A-APR.7b c. I can divide two rational expressions.A-APR.7b d. Honors: I can rewrite rational expressions that involve

Students developed proofs in Math 2 that included paragraph, flow and two-column. Prior knowledge from Math 2 that will need to be reviewed includes congruent triangles and parallel lines. A parallelogram is defined as a quadrilateral with opposite sides parallel. Given that definition, students should prove opposite sides are congruent; adjacent angles are supplementary; and opposite angles are congruent. Students should prove the properties of the diagonals of parallelograms and be able to identify the parallelogram given the properties of the diagonals. The special parallelograms are rhombus, rectangle, and square.

Circles are studied in 7th grade; therefore, the definition, parts of a circle (including the vocabulary for those parts) and the notation used to identify the parts should be a focus. Consider using technology such as GeoGebra or Desmos/Geometry while studying circles. Students should become flexible in strategically adding auxiliary lines such as radii or chords to help solve problems. Applications of inscribed angles include:

• the arcs between parallel chords of a circle are congruent • an angle inscribed in a semicircle is a right angle • opposite angles in an inscribed quadrilateral are supplementary

Students should understand the relationship between the perpendicular bisector and the center of a circle in that given two of the criteria the other must also be true. Relationships between congruent chords should include:

• equidistant from the center • they intercept congruent arcs

Consider identifying the relationship between lengths of chords/tangents/secants by the location of the intersection (inside the circle, on the circle, and outside the circle). Students can use the same relationship for all three cases (product of the lengths from intersection to the point on the circle are equal).

Students should understand radians as a unit of measure to describe the size of an angle. Specifically, they should know and be able to use the fact that a radian is the quotient of the arc length and the radius to solve problems. For example, given the radian measure and the arc length find the radius. Students should be able to calculate arc lengths and areas given angle measures in degrees or radians. It is not a focus of the Math 3 standards for students to convert between degrees and radians. The intent is for students to understand both as a measure of an angle and be flexible in using either to solve problems.

Students should understand how the equation of the circle is connected to the definition of a circle (all points equidistant from a given point). Consider having students investigate the connection to the Pythagorean Theorem / Distance Formula. Students will need to use the process of completing the square (previously studied in Math 2 and used when writing the inverse of a quadratic function earlier in Math 3) to rewrite the equation of a circle. The standard F-TF.2 refers to the “unit circle” as a way to define a circle centered at the origin with a radius of 1 unit. It is not the intent of the standard for students to study or discover additional properties of the unit circle. Students should use the unit circle to develop an understanding of the

• sine function as the relationship between an angle measure in radians to the y coordinate • cosine function as the relationship between an angle measure in radians to the x coordinate.

Consider reviewing right triangle trigonometric ratios, from Math 2, when beginning this study. The honors extension is for students to generalize beyond the unit circle and be able to determine the coordinates on a circle given the radius, 𝑟,as (𝑟𝑐𝑜𝑠𝜃, 𝑟𝑠𝑖𝑛𝜃).

Outcome 19: I can use trigonometric functions to model and solve problems. (3 days) a. I can graph sine and cosine functions and identify key features

including period, amplitude, and midline. F-IF.4, F-IF.7 b. I can use the sine function to model patterns of periodic

change. F-TF.5 c. I can interpret key features of a sine function in context given a

F-TF.1 states students should understand the radian measure of an angle is the domain for trigonometric functions; therefore, graphs of sine and cosine functions should focus on using radians. Students will graph sine and cosine functions to analyze and identify key features. Next, students will model contextual situations using the sine function. The honors extension is to also model using the cosine function. Modeling with the sine function provides students the opportunity to revisit transformations.

Students should be able to distinguish between the types of studies including understanding how randomization should be used in each. For instance, observational studies typically do not use randomization while it is essential to a well-designed experiment. Student descriptions of representative samples should focus on random sampling methods that create samples which are representative of the population of interest (the population about which the sample is used to make inferences). The intent of the S-IC.4 and S-IC.5 is for students to use simulation. Students used simulations in 7th grade and Math 2 to explore probability. Through the use of simulation, students develop an understanding of margin of error and statistical significance. Students should understand that the margin of error allows us to decide statistical significance because any sample statistic which lies outside the margin of error is “statistically significant” (meaning it is not likely to happen just by chance alone, according to the simulation results.)

This module allows the opportunity to review all functions. Students should be able to compare key features of any two functions represented differently (e.g., one as a table and one as a function rule). Focus on using the graphs and tables to identify and compare key features. Students apply their knowledge of building the different functions to create systems of equations. They are not expected to solve complex systems algebraically, but should focus on more efficient methods such as tables, graphs, and using technology. The honors extension is solving some systems algebraically.
