- Graphing quadratic equations
- This lesson will help students quickly graph a quadratic equation. It will also help them to understand the purpose of completing the square.
- Format: lesson plan (grade 9–12 Mathematics)
- By Kathy Schadt.
- Homerun hoopla
- This lesson is designed for students to gather and analyze data about baseball figures. The student will use the Internet or other resources to collect statistical data on the top five home run hitters for the current season as well as their career home run totals. The students will graph the data and determine if it is linear or non-linear.
- Format: lesson plan (grade 8–12 Mathematics)
- By Anne Walters.
- Introduction to polar coordinates
- The student will be introduced to the definition of polar coordinates, how to graph them, and how to compare them to rectangular coordinates.
- Format: lesson plan (grade 9–12 Mathematics)
- By vicky burlington.
- Investigating linear equations
- Using a graphic calculator to compare the slope and y-intercept of lines to understand the slope-intercept form (y = mx+b) and what effect each has on a line.
- Format: lesson plan (grade 8–12 Mathematics)
- By Misty Jarman.
- Learning to use R statistical software for data mining — An extension of linear regression to multiple variables
- In Understanding data mining: Extracting, organizing, and analyzing large sets of data, page 3
- In this lesson, students will use the free R statistical software to navigate through the basics of data mining, a process in which the effects of individual variables can be determined. Students will utilize multiple methods of variable selection — forward selection, backward selection, and stepwise selection — in an attempt to determine which variables are most influential in a given situation.

- Learning to use R statistical software for linear regression — An alternative to the graphing calculator
- In Understanding data mining: Extracting, organizing, and analyzing large sets of data, page 2
- Students often learn how to do linear regression activities using a graphing calculator. This lesson provides an opportunity to complete these same types of assignments using R statistical software. Students will use this free software to create scatter plots and to develop linear regression models that can be used to make predictions.

- By Dail Midgette.
- To be or not to be... linear
- The student will determine the correlation between two variables. They will graph ordered pairs on a coordinate plane, determine a best fit line, find slope and intercepts, and write the equation of a line. This lesson plan is geared for both 8th grade math and algebra.

- Understanding data mining: Extracting, organizing, and analyzing large sets of data
- Mathematics students in grades nine through twelve will be able to extract useful information from large sets of data that represent multiple disciplines. Using these real-world applications, students will analyze data and use their findings to make predictions and to provide solutions to problems.
- Format: lesson plan (multiple pages)
- Working with parabolas
- In CareerStart lessons: Grade eight, page 2.3
- In this lesson, students graph a quadratic equation to find a solution to a hypothetical scenario involving event planners.
- Format: lesson plan (grade 9 Mathematics and Science)
- By Debbie Brooks, Peggy Dickey, and Jan Sullivan.
