Title: Beep! Beep! Move Over! I Am Going to Be Late!
Description: During this lesson, students will investigate how to "clear up" the "Traffic Jam."  They will be using large manipulatives (their bodies), small manipulatives (carpet squares), and technology (the Java applet) to find the relationship among numbers and patterns.   The carpet square will be used as "car lengths", while the students use their bodies as "vehicles" to try to find the minimum number of moves required to clean up the "Traffic Jam"!

Title: Show Me The Money
Description: Just what is a penny worth? Students explore various websites or printed fact sheet investigating the history and changes in density of pre- and post- 1982 pennies. They will also research the current price of copper and zinc and compare the ratios or pre and post 1982 pennies. Students then complete a hands-on lab experiment to determine the mass, volume, and density of pre and post 1982 pennies. Students determine if the pennies are worth saving?

Title: Exploring Linear Data
Description: In this lesson, from Illuminations, students model linear data in a variety of settings. Students can work alone or in small groups to construct scatterplots, interpret data points and trends, and investigate the notion of line of best fit.

Title: Least Squares Regression
Description: In this nine-lesson unit, from Illuminations, students interpret the slope and y-intercept of least squares regression lines in the context of real-life data. Students use an interactive applet to plot the data and calculate the correlation coefficient and equation of the least squares regression line. These lessons develop skills in connecting, communicating, reasoning, and problem solving as well as representing fundamental ideas about data.

Title: Mathematics as Communication
Description: This lesson, from Illuminations, focuses on interpreting and creating graphs that are functions of time. Students complete four activity sheets that focus on graphs of time vs. speed and how many times an event occurred in a specific amount of time.

Title: The Effects of Outliers
Description: This lesson, one of a multi-part unit from Illuminations, provides students with the opportunity to investigate the relationship between a set of data points and a curve used to fit the data points, using a computer-based interactive tool. Using the Regression Line Applet, students investigate the effect of outliers on a regression line and easily see their significance.

Title: Traveling Distances
Description: In this lesson, one of a multi-part unit from Illuminations, students interpret the meaning of the slope and y-intercept of a graph of real-life data. By examining the graphical representation of the data, students relate the slope and y-intercept of the least squares regression line to the real-life data. They also interpret the correlation coefficient of the resulting least squares regression line. This lesson incorporates an interactive regression line applet.

Title: Building Bridges
Description: In this lesson, from Illuminations, students attempt to make a transition from arithmetical to algebraic thinking by extending from problems that have single-solution responses. Values organized into tables and graphs are used to move toward symbolic representations. Problem situations involving linear, quadratic, and exponential models are employed.
