Subject: Mathematics (9 - 12)
Title: Systems of Linear Inequalities Project
Description: The systems of linear inequalities project was designed to be used in an Algebra IB class after a preliminary lesson on systems of linear inequalities. The project is to be graded per group based on the work completed and presentation to the class. Each group is required to use a graphing calculator in its presentation.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 (8 - 12)
Title: Graphing Stations
Description: This activity will be used to review all the forms of linear equations and to review graphing linear, their parallels and their perpendiculars. All the forms of linear equations will be reviewed for testing purposes. Students will participate in a round robin activity to help students master objectives before unit test.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 (9 - 12), or Technology Education (9 - 12)
Title: Math is Functional
Description: This lesson is a technology-based activity in which students extend graphing of linear functions to the use of spreadsheet software. After students have become proficient in constructing a table of values, students are able to efficiently graph equations with more extensive computational requirements. Furthermore, inquiry and discovery about slope and y-intercept will help students conceptualize material normally presented in Algebra I textbooks.

Title: You Mean ANYTHING To The Zero Power Is One?
Description: This lesson is a technology-based project to reinforce concepts related to the Exponential Function. It can be used in conjunction with any textbook practice set. Construction of computer models of several Exponential Functions will promote meaningful learning rather than memorization.

Title: Apple Pie Recording Chart
Description: This reproducible activity sheet, from an Illuminations lesson, prompts students to use strings and rulers to measure and record the distance around several round objects, as well as the distance across the middle of those objects.

Subject: Mathematics
Title: Gallery Walk
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.

Title: Think of a Graph
Description: This reproducible transparency, from an Illuminations lesson, asks students to sketch a graph in which the side length of a square is graphed on the horizontal axis and the perimeter of the square is graphed on the vertical axis.

Subject: Mathematics
Title: Bathtub Water Levels
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.

Subject: Mathematics
Title: Automobile Mileage: Comparing and Contrasting
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.

Title: Graph Chart
Description: Using this reproducible chart, from an Illuminations lesson, students record the independent and dependent variables, the function, symbolic function rule and rationale for a set of graphs. This resource can also be used as an overhead transparency so students can share their results with their classmates.

Title: How Should I Move?
Description: In this Illuminations lesson, a motion detector is used to help students understand graphs and equations. Students experience constant and variable rates of change and are challenged to consider graphs where no movements are possible to create them. Multiple representations are used throughout the lesson to allow students to build their fluency with in how graphs, tables, equations, and physical modeling are connected. The lesson also allows students to investigate multiple function types, including linear, exponential, quadratic, and piecewise.

Title: Numerical Analysis
Description: In this lesson, one of a multi-part unit from Illuminations, students use iteration, recursion, and algebra to model and analyze a changing fish population. They use an interactive spreadsheet application to investigate their models.

Karl's Function Plotter
http://www.karlscalc...
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." **Possible alternative resource- http://www.fooplot.com/#W3sidHlwZSI6MCwiZXEiOiJ4XjIiLCJjb2xvciI6IiMwMDAwMDAifSx7InR5cGUiOjEwMDB9XQ--
