Subject:
Mathematics (8 - 12)
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 Career-Ready Standards showcase lesson plan.
Subject:
Mathematics (8 - 12)
Title:
Exploring Slope
Description:
The purpose of this lesson is to help students see the real world application of slope. The students will view a movie clip of slope, calculate the slope of stairs in the school building, and analyze results.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.
Subject:
Mathematics (7 - 8)
Title:
Heads Up!
Description:
The lesson is a hands-on project. Students will work in pairs to gather various measurements, organizing the data into a provided chart. The measurements will be used to review, reinforce, and introduce skills such as measures of central tendency, coordinate graphing, and various ways of representing data (i.e., stem-and-leaf plots, box-and-whisker plots, frequency tables, etc.).
Subject:
Mathematics (8 - 12)
Title:
What is the slope of the stairs in front of the school?
Description:
The purpose of this lesson is to help students apply the mathematical definition of slope to a concrete example. The students will learn to make the appropriate measurements and apply the formula to calculate the slope of the stairs experimentally.

Finding Our Top Speed
Add Bookmark
Description:
This Illuminations lesson sets the stage for a discussion of travel in the solar system. By considering a real-world, hands-on activity, students develop their understanding of time and distance. The mathematics necessary for the lesson relate to measuring time and distance as well as graphing to portray the data collected.

Automobile Mileage: Age vs. Mileage
Add Bookmark
Description:
In this lesson, one of a multi-part unit from Illuminations, students plot data about automobile mileage and interpret the meaning of the slope and y-intercept of the least squares regression line. By examining the graphical representation of the data, students analyze the meaning of the slope and y-intercept of the line and put those meanings in the context of the real-life application. This lesson incorporates an interactive regression line applet.

Automobile Mileage: Comparing and Contrasting
Add Bookmark
Description:
In this lesson, one of a multi-part unit from Illuminations, students compare and contrast their findings from previous lessons of the unit. This lesson allows students the time they need to think about and discuss what they have done in the previous lessons. This lesson provides the teacher with another opportunity to listen to student discourse and assess student understanding.

Bathtub Water Levels
Add Bookmark
Description:
In this lesson, one of a multi-part unit from Illuminations, students examine real-life data that illustrates a negative slope. Students interpret the meaning of the negative slope and y-intercept of the graph of the 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 least squares regression line. This lesson incorporates an interactive regression line applet.

Exploring Linear Data
Add Bookmark
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.

Gallery Walk
Add Bookmark
Description:
In this lesson, one of a multi-part unit from Illuminations, students view the work of other students in the class and explain their own work. Students move from graph to graph during this time and, without any talking, view the work of their classmates. While on their Gallery Walk, the students think about the data their classmates plotted and whether or not the information accompanying each graph seems appropriate. Each pair of students then stands next to their own work and explains one of the graphs.

Least Squares Regression
Add Bookmark
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.

Building Bridges
Add Bookmark
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.

Supreme Court Handshake
Add Bookmark
Description:
In this lesson, one of a multi-part unit from Illuminations, students explore the handshake problem, a classic problem in mathematics that asks, How many handshakes occur when n people shake hands with each other? Groups work to determine how many handshakes take place among the nine Supreme Court justices, and then generalize the problem to determine the number of handshakes in any size group. Students explore the problem using a verbal description, a table, a graph, a picture and an algebraic formula.
