Students explore the concept of multi-step equations. In the multi-step equation lesson, students solve equations by the 'party method'. Students make a flip book that shows the steps in solving multi-step equations.

Tenth graders investigate the Elimination Method in the solving of equations. They solve the equation using this method in examples with the teacher and then transfer the new knowledge to independent practice.

Solve a linear equation where the coefficients are represented by letters.

Review linear regression and analyze how well this model fits the data. You will also be introduced to residuals and the correlation coefficient, and use these tools to determine whether or not a linear model is the best fit for a set of...

An interactive program where students will explore regression lines. Students will be introduced to the correlation coefficient and come to understand what it represents through the given exploration. Requires Java.

Clemson University offers an excellent site of linear thermal expansion lab. Includes experiment, images, charts, links, questions, and much more.

This lesson shows how to solve a second order homogeneous equation with constant coefficients.

This lesson shows one method of solving nonhomogeneous second order linear equations.

Solve a linear equation for a variable where the coefficients are represented by letters. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Practice these problems combining like terms with rational coefficients.

[Free Registration/Login may be required to access all resource tools.] This lesson covers factoring quadratics when the leading coefficient is 1.

The correlation coefficient r measures the direction and strength of a linear relationship. Calculating r is pretty complex, so we usually rely on technology for the computations. We focus on understanding what r says about a scatterplot.

Practice combining like terms for expressions that have rational coefficients. This requires adding and subtracting fractions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or...

Practice combining like terms for expressions that have rational coefficients. This requires adding and subtracting fractions.

Practice combining like terms with negative coefficients.

Practice problems combining like terms with negative coefficients and distribution.

[Free Registration/Login may be required to access all resource tools.] Use a calculator to create a scatter plot and to determine the equation of the line of best fit.

Students play a game to identify the correct equation for the graph displayed. Through the game setting, they review graphs and equations of linear, quadratics, and absolute value functions.

This page provides a good discussion of correlation coefficients (r,) which indicate the "strength of the linear association between variables." Includes formulas and scatter plots. Some prior knowledge of statistics might be helpful.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

An investigation of homogeneous second order linear differential equations with constant coefficients gives examples and shows the steps in how they are solved.

Overview of correlation coefficient, or a number between 1 and -1 which measures the degree to which two variables are linearly related. It is followed by a description of the Pearson product moment correlation coefficient.

This activity is designed to help students work with linear regression models, error, correlation coefficients and coefficients of determination. In this activity students not only deal with the mathematical concepts of regression but...

Defines thermal expansion and elaborates on the concept of linear expansion. Provides the equation for linear expansion and includes an interactive JavaScript form which allows the visitor to investigate the relationship between...
