● Students should look at algebraic manipulation as a meaningful enterprise, in which they seek to understand the structure of an expression or equation and use properties to transform it into forms that provide useful information (e.g., features of a function or solutions to an equation). (A/F)

● Seeing mathematics as a tool to model real-world situations should be an underlying perspective in everything students do, including writing algebraic expressions, creating functions, creating geometric models, and understanding statistical relationships. (M)

● In particular, students should recognize that much of mathematics is concerned with understanding quantities and their relationships. They should pick appropriate units for quantities being modeled, using them as a guide to understand a situation, and be attentive to the level of accuracy that is reported in a solution. (N-Q)

● Students should understand the effects of parameter changes and be able to apply them to create a rule modeling the function. (F-BF.B.3)

Unit of Study 1: Investigations and Functions Length of Unit 14 days (August 20–September 7, 2018)

Unit Learning Trajectory

● The focus of this chapter is to give students the opportunity to share their current mathematical knowledge with their study teams as they work together to solve problems and become comfortable talking about mathematics by investigating mathematical questions and creating logical and convincing arguments to support their findings. In their previous courses, they have established classrooms norms (e.g., working in study teams, explaining thinking, investigating mathematics) and class procedures for graphing organizers, Learning Logs, and homework, and to review vocabulary.

● In Section 1.1, students create multiple representations of a function using a graphing calculator and review describing graphs of functions using precise mathematical language. Students learn how a parent graph and parameters define a family of functions and explore the results of combining linear functions. In Section 1.2, students engage in modeling problems to preview concepts in the course. Mastery of the concepts in Section 1.2 should not be expected yet, as these topics will be revisited, extended, and applied to new situations in upcoming chapters.

● Further work on function families, key features of graphs of functions, and multiple representations of functions will continue in Chapters 2, 5, and 7. In Chapter 2, students will generate families of functions from parent functions starting with the parent function f(x) = x2. They will make generalizations about functions by stretching, compressing, reflecting, and translating parent functions. Students will extend their learning to inverse and logarithmic functions in Chapter 5 and trigonometric functions in Chapter 9.

Unit of Study 2: Transformations of Parent Graphs Length of Unit 18 days (September 10–October 3, 2018)

Unit Learning Trajectory

● An important theme of this chapter is generalizing as students generate families of functions by applying transformations to their parent functions.

● In Section 2.1, students apply transformations to the parent function f(x) = x2 to develop a general equation in the form f(x) = a(x - h)2 + k for the family of quadratic functions. Students review how to sketch a parabola by identifying its orientation, vertical stretch (or compression), and vertex. In Section 2.2, students continue to develop families of functions by applying transformations to other parent functions, including f(x) = 1/x, f(x) = √ x, f(x) = bx, f(x) =|x|, and f(x) = x3 and create a Function Family Graphic Organizer describing the role of (h, k) for each. Students create functions to model relationships between quantities and explore different ways to compare the growth of their models over time. In Section 2.3, students review completing the square for parabolas and circles, which they learned in Core Connections Integrated II.

● Further work on families of functions will continue in Chapters 5 and 9. In Chapter 5, students will be introduced to logarithmic functions, and in Chapter 9, students will be introduced to trigonometric functions. Students will be asked to graph members of these new families of functions and write a general equation for the function family. Throughout the course, they will learn to choose the appropriate function to model a particular relationship.

Unit Learning Trajectory

● The focus of this chapter is to gain a stronger understanding of the meaning of solutions and to apply prior knowledge of equations, inequalities, and systems to solve problems.

● In Section 3.1, students review strategies for solving single-variable equations and use graphing as a tool for solving equations and systems as well as visualizing the solutions. Students gain a deeper understanding of the meaning of solutions. They learn multiple ways to determine and represent solutions. In Section 3.2, students extend their understanding of solving and solutions to inequalities and systems of inequalities. Students also explore linear programming as a way to determine solutions that meet a set of constraints.

● Further work on solving and solutions will continue in Chapter 11 as students understanding of linear systems in two-variables to solving systems of linear equations in three variables. At the end of Chapter 11, they will solve a system of three equations in three variables to determine the equation of a parabola, y = ax2 + bx + c, that passes through three unknown points. They will continue to use graphing as tool to solve polynomial equations in Chapters 8 and trigonometric equations in Chapter 9.

● Seeing mathematics as a tool to model real-world situations should be an underlying perspective in everything students do, including writing algebraic expressions, creating functions, creating geometric models, and understanding statistical relationships. (M)

● In particular, students should recognize that much of mathematics is concerned with understanding quantities and their relationships. They should pick appropriate units for quantities being modeled, using them as a guide to understand a situation, and be attentive to the level of accuracy that is reported in a solution. (N-Q)

Unit Learning Trajectory

● The focus of this chapter is to introduce students to the fundamentals of experimental design and studies and the limitations of each. This unit emphasizes the importance of random sampling for studies and random assignment for experiments and develops the concept of using a normal probability density model to calculate percentiles.

● In Section 4.1, students learn about surveys as a type of observational study and gain experience with two common sources of bias in surveys. In Section 4.2, students compare and contrast experiments and observational studies through an experiment and learn the importance of randomness for experiments. In Section 4.3, students construct relative frequency histograms and model them with normal distributions using the calculator to compute proportions and percentiles. In Section 4.4, students explore geometric modeling. Students visualize the cross-sections of different objects by exploring where two-dimensional shapes occur within three-dimensional figures and visualize solids of revolution. This section ends with a design problem that students need to optimize.

● Further work on statistics will continue in Chapter 6, as students explore inferential statistics, using samples to make predictions about populations.

Misconceptions

● Students believe inferences from samples to populations can be done only in experiments. They need to realize that inferences can be made in samplings and observational studies if data are collected through random processes.

● Students believe population parameters and sample statistics are the same. For example, they may think there is no difference between population mean, which is a constant, and sample mean, which is a variable.

● Students believe that making decisions is simply comparing the value of one observation of a sample statistic to the value of a population parameter, not realizing the distribution of the sample statistic needs to be created.

● Students believe all bell-shaped curves are normal distributions. A bell-shaped curve is normal when 68% of the distribution is within one standard deviation of the mean, 95% within two, and 99.7% within three standard deviations.

● The focus of this chapter is to learn about inverse functions and investigate the relationship between functions and their inverses. Students explore multiple representations of functions and their inverses, and recognize that many functions have inverses that are not functions.

● In Section 5.1, students examine relationships called inverses and investigate multiple representations of inverse functions. In Section 5.2, students investigate a new family of functions called logarithms, which are the inverse of exponential functions. Students convert equations in exponential form to logarithmic form and vice versa. They also apply transformations to the graph of the parent function, f(x) = log(x).

● Further work on transformations of parent functions will continue in Chapter 8 with polynomial functions and Chapter 9 with trigonometric functions.

● The focus of this chapter is to determine complex probabilities through simulations and introduce inferential statistics and statistical hypothesis testing. Students use area models or tree diagrams to understand counterintuitive probability problems.

● In Section 6.1, students perform simulations to estimate complex probabilities. Students determine sample-to-sample variability which they use to put a margin of error on characteristics they predict about a population. In Section 6.2, students extend their learning to conduct a statistical hypothesis test and observe the effect of sample size on sample-to-sample variability. Students learn how statistics are used in manufacturing for both quality control and process control. Section 6.3, students evaluate decisions and strategies based on area models of probability and use probability to solve problems whose solutions are counterintuitive.

● Further work on inferential statistics will continue in a formal statistics course.

● The focus of this chapter is to apply knowledge of families of functions from Chapters 2, 5, and 7 to include polynomial functions.● In Section 8.1, students investigate the connection between the graph and equation of a polynomial function and understand the relationship

between the factors of a polynomial equation and the x-intercepts of the graph of a polynomial. Students sketch the graphs of polynomials without using a graphing calculator and write equations from graphs. In Section 8.2, students further develop their understanding of imaginary and complex numbers (introduced in Core Connections Integrated II) and recognize that polynomial functions can have complex roots. In Section 8.3, students divide polynomials by a known factor to find other factors, allowing them to determine complex and irrational roots of some cubic and quartic functions.

● Further work on function families will continue in Chapter 9. In Chapter 9, students study trigonometric functions and investigate the effects of transformations on the graphs of sine and cosine functions. Students will further develop their algebra skills in proving formulas for sums of series in Chapter 10, studying rational functions in Chapter 11, and solving trigonometric identities in Chapter 12.

● The focus of this chapter is to apply and extend knowledge about arithmetic and geometric sequences to the development of formulas for sums of geometric and arithmetic sequences while further developing their algebraic skills.

● In Section 10.1, students devise methods for determining sums of arithmetic sequences and explore proof by induction. In Section 10.2, students devise methods for determining sums of geometric sequences where the last term is defined. Students also learn to represent and calculate sums of some infinite series.
