Lessons (with descriptions and correlation)

Equal Salaries for Equal work?
This task asks students to compare additive and multiplicative growth (represented by linear and exponential models) to make predictions and solve problems within the context of gender-based salary differences. In doing this task, students analyze data sets, create scatter plots, determine the most appropriate mathematical model, and justify their model selection.Uses scatter plots to compare two sets of data.

Season Pass

This task asks students to analyze and fit a mathematical model to data in order to answer questions about maximizing revenue. Students may use various methods to determine a quadratic function that fits the mathematical model and helps answer the questions.

*A Graphical Approach to the Quadratic Formula

P1.a, b, c: Quadratic functions

This is an approach to the quadratic formula based on moving parabolas 

 Absolute Values of Linear Functions

 

Students will make predictions, using geometric intuition, about the paths of golf balls, analyze graphs of functions, and determine equations that model the path.

*Toothpicks and Transformations (Quadratic Functions)

The lesson begins with a review of transformations of quadratic functions—vertical and horizontal shifts, and stretches and shrinks. First, students match the symbolic form of the function to the appropriate graph, then given the graphs, students analyze the various transformations and determine the equation for the functions. This review is followed by an activity where students explore a mathematical pattern that emerges as they build a geometric design with toothpicks. The pattern is quadratic, and the students determine the mathematical model in several different forms.

*Quadratic Equations Lesson Plan

Students will be able to derive and apply the quadratic formula to various quadratic equations. Students will also be able to interpret when is the best situation to use the quadratic formula or another process to solve a quadratic equation.

Maximizing Profits on Donut Sales 

Quadratic functions: graphs, intercepts, vertex, symmetry; linking representations; quadratic equations; intersections of lines and quadratic curves

*Open Response Quadratic Function Problem

            Students must be able to write and graph the function; give the domain and range for the function; determine an equation and graph quadratic through a given point for a given function.

Bridge on the River Quad

In the first part of this activity, students graph a quadratic function that models the shape of a bridge trestle. They then solve the related quadratic equation by completing the square, recording each step as they complete it. This list of steps is generalized to deduce the quadratic formula. In the second part of the activity, students store the formula in their graphing calculator, compare its results with those of the Equation Solver, and use it to solve several other quadratic equations. 

Leo’s Paintings

This task allows students to integrate algebra and geometry as they generate a quadratic inequality from a proportional relationship. (Quadratic contextual area problem)
 
*Graphing Quadratic Functions
In this activity, students graph quadratic functions and study how the constants in the equations compare to the coordinates of the vertices and the axes of symmetry in the graphs. The first part of the activity focuses on the vertex form, while the second part focuses on the standard form. Both activities include opportunities for students to pair up and play a graphing game to test how well they really understand the equations of quadratic functions.

A Study of Malaria and Sickle Cell Anemia

P1.a, b: Quadratic Functions; E2.b, c: Non-Linear functions
Teacher and student PDF form available
Hands-on activity to simulate biological events. Involves finding maximum of quadratics, starting with ax^2+bx=0 and ending with general quadratics. Method of solution is by symmetry, that is, maximum is half way between two roots. Students then use factoring. Some quadratics factor "easily", others employ quadratic formula if you wish.

*Building Polynomial Functions

This lesson focuses on having students make connections among different classes of polynomial functions by exploring the graphs of the functions. The questions in the activity sheets allow students to make connections between the x-intercepts of the graph of a polynomial and the polynomial's factors. This activity is designed for students who already have a strong understanding of linear functions, some knowledge of quadratic functions, and what is meant by a polynomial function.

Match That Function

This task requires students to analyze a situation, describe the appropriate function for the situation using multiple representations, and make connections among the representations. The task provides an opportunity to compare various types of functions.
 
The Devil and Daniel Webster
Students will be able to:
Bighorn Sheep
In this task, students model a situation with exponential functions in order to make predictions and solve problems.

*Exponential Growth and Exponential Functions

Humorous – check out problem for good problem. Students will model exponential growth and explore graphing exponential functions through transformations

Reading This Could Help You Sleep: Caffeine in Your Body (Teacher & student PDF form)

This unit is an introduction to exponential functions using elimination of coffee from the body. Connects to half-life.

 Get Out the Lead

Requires that, "Reading This Could Help You Sleep: Caffeine in Your Body" be covered earlier in the semester. This unit uses logarithms to "undo" exponentiation in solving exponential equations in a study of build-up and elimination of lead from the body. Can serve as an introduction to the need for a logarithm function.

 End Behaviors of Polynomial Functions

Students will graph polynomial functions and categorize them by their end behavior; analyze how end behavior is affected by the lead coefficient and the exponent of the highest degree in the function. 

*Asymptotes and Zeros of Rational Functions

Students will graph polynomial functions and examine their zeros and y-intercepts; analyze how the zeros and y-intercepts of the numerator and denominator affect the graph of a rational function.
*Function Transformations
This task allows students to use multiple representations to discover the transformational patterns of a piecewise function.
