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): [MA2015] 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]

Title: Predict the Future?
Description:
Students will use data collected and a "bestfit line" to make predictions for the future. The example the students will be working on for this lesson will demonstrate an exponential regression.
Standard(s): [MA2015] 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)

Title: Cosmic Measurements
Description:
In this lesson, students will use hands on inquiry in cooperative learning groups to understand, develop and analyze common measurements used by astronomers. Students will use common objects such as straws, twizzlers, or toothpicks to measure the distance from a fixed object or central location to other objects. The students will then use this information to develop a unit of measurement like the astronomical unit. The students will measure the speed of an object such as a remote control car and use this to develop a unit similar to the lightyear. 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): [MA2015] ALC (912) 10: Critique measurements in terms of precision, accuracy, and approximate error. (Alabama)
