Subject: Mathematics (8), or Technology Education (9  12) Title: We Love to Graph!
Description: The students will review plotting points on a Coordinate Plane through an interactive website. They will also practice changing the slope and yintercept on the website in order to see the effects. After this review, the students will work in groups to plot points and use slope to spell out letters of the alphabet. The students will then unscramble the letters to spell out "We Love to Graph!"This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project, funded by the Malone Family Foundation.
Subject: Mathematics (7  8) Title: Heads Up!
Description: The lesson is a handson 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., stemandleaf plots, boxandwhisker 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.

Description: This Illuminations lesson sets the stage for a discussion of travel in the solar system. By considering a realworld, handson 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. Thinkfinity Partner: Illuminations Grade Span: 6,7,8
Subject: Mathematics Title: Automobile Mileage: Age vs. Mileage
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students plot data about automobile mileage and interpret the meaning of the slope and yintercept of the least squares regression line. By examining the graphical representation of the data, students analyze the meaning of the slope and yintercept of the line and put those meanings in the context of the reallife application. This lesson incorporates an interactive regression line applet. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: Automobile Mileage: Comparing and Contrasting
