Title: Penny Drop That Thang!
Description:
This lesson is designed to introduce and extend students' knowledge on slope and linear equations. Students will be able to differentiate finding the slope to creating a linear equation.
This is a College and CareerReady Standards showcase lesson plan.
Standard(s): [MA2013] AL1 (912) 23: Explain why the xcoordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.* [AREI11]
Subject: Mathematics (8  12)

Title: Systems of Equations: What Method Do You Prefer?
Description:
The purpose of this lesson is to help students apply math concepts of solving systems of equations to real life situations. The students will use the three methods of graphing, substitution, and elimination to solve the system of equations.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Standard(s): [MA2013] ALT (912) 22: Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context. [ACED3]

Title: Shedding the Light
Description:
In this fourlesson unit, from Illuminations, students investigate a mathematical model for the decay of light passing through water. The goal of this investigation is a rich exploration of exponential models in context. Students examine the way light changes as water depth increases, conduct experiments, explore related algebraic functions using an interactive Java applet and analyze the data collected.
Standard(s): [MA2013] DM1 (912) 3: Use the recursive process and difference equations to create fractals, population growth models, sequences, series, and compound interest models. (Alabama)

Title: Karl's Function Plotter
Description:
Karl's Function Plotter is an interactive tool in which functions can be entered and the resulting graph displayed.
**Under the Read Me it describes the following restrictions:
"Usage Restrictions: Plotting graphs is computationally intensive. To limit the burden on the internet service provider for Karl's Calculus Tutor, you will be restricted from plotting another graph after you've plotted one for 3 minutes after plotting a small, 5 minutes after plotting a medium, 12 minutes after plotting a large, 20 minutes after plotting an extra large, and 40 minutes after plotting a huge. Tiny plots incur no delay, so you can use them to preview what the larger plot will look like. So enter your fields carefully before clicking the Plot Now button. Note that if you get an error when you attempt to plot, you will not be delayed in trying again."

Title: Function Transformations
Description:
Explore how simple transformations affect the graph of a function with this interactive.
Standard(s): [MA2013] PRE (912) 16: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. (Key features include intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. Determine odd, even, neither.)* [FIF4] (Alabama)
