The goal of this task is to examine some population data for large cities from a modeling perspective. Learners are asked to decide if the population data can be accurately modeled by a linear, quadratic, and/or exponential function, and...

In this task, 8th graders are presented with the equation for a linear function and asked to identify which of six problem situations the equation could represent. Aligns with 8.F.B.

In this activity, students' examine how temperature affects the rate of gas production during a chemical reaction. They measure this rate by recording the pressure variation using a pressure sensor and model the pressure data using a...

This set contains statistics questions regarding non-linear association: straightening data using logarithmic and power transformations. The student analyzes which type of regression will best model the data.

Students use a Force Sensor to collect weight versus number data for a collection of identical pennies and model the data using a linear equation. They will then interpret the slope as it relates to independent and dependent variables.

In this activity, students explore the nonlinear model for a simple pendulum. They use the calculator to solve higher order differential equations.

Given some information about a real-world context, analyze expressions containing unknown variables that model that context.

In this task, students are shown a table of population data for the city of London and are asked to explore whether a linear, quadratic, or exponential function would be appropriate to model relationships within the data. They are next...

[Free Registration/Login may be required to access all resource tools.] In this lesson students draw a scatter plot of data, find and draw the function that best fits that data, and make predictions from that information. Students watch...

Based off of the hit television show NUMB3RS, this lesson introduces students to exponential equations, their graphs, and their application in the real world. The lesson is framed in the context of the number of cell phone users for a...

[Free Registration/Login may be required to access all resource tools.] Learn how to solve problems involving inverse variation.

[Free Registration/Login Required] Students will learn how to use the best method to solve a system of linear equations and will use systems of linear equations to model real-life problems.

Wikipedia explains the statistics term, "linear regression." Includes table of contents, hyperlinked terms, and formulas.

Dozens of statistical terms are defined and illustrated in this glossary.

Learn about three models of population growth: linear, exponential, and logistic. Then conduct a population experiment to see how populations can work in the real world, and see how linear graphs can help simplify complicated ones.

This site is a demonstration of Comparing data sets using statistics and forming a linear model from a given set of data. Examples and a practice test are included.

Solve word problems that involve systems of linear inequalities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Thanksgiving Holiday activity for Algebra students. Linear data taken from the internet and used to create a linear model of the class data.Students will then discover the slope of the line is the speed of the car in miles per hour....

View the differences in intermolecular interactions between linear and branched polymers.
