Students will write exponential equations based on the percent of increase of college costs and will graph and interpret these equations. Students will then use an inflationary equation based on the USA TODAY Snapshot, "Paying college...

In this lesson, the Gaussian Elimination method is used to solve systems of linear equations. Provides several formulas and examples for understanding.

Twenty-seven problems present a variety of practice solving linear systems by substitution. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...

A brief overview of three methods used to graph lines is presented through examples. Slope-intercept, point-slope, and intercept form are demonstrated step-by-step along with a review of the formula for finding the slope of a line.

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. This resource explains this method by showing an example along with a video.

Check for college math readiness using this problem sampler. Problems cover high school algebra topics, including linear and quadratic equations, factoring, radicals, rational expressions, synthetic division, complex numbers and more....

The primary focus in this activity is on parallel lines and equivalent equations. In Activity 1 and Activity 2, the class collectively will create a system of parallel and coinciding lines. It is important to focus on parallel lines...

In this mini-lesson, we will explore the world of matrices by finding the answers to questions like how to solve systems of equations with matrices, how to solve matrices, and matrix operations with examples and formulas while...

The primary focus should be on slope as rate of change and piecewise functions. This activity allows exploration of multiple types of slope; i.e., positive slope, negative slope, or zero slope for students to build their understanding of...

This comprehensive study guide highlights the main terms and formulas needed to review linear systems, specifically solving by graphing and substitution. Examples are included.

[Free Registration/Login may be required to access all resource tools.] Recognize patterns of polynomials that are the product of two binomials.

This task is designed to make students think about the meaning of the quantities presented in the context (of coffee needs) and choose which ones are appropriate for the two different constraints presented. Aligns with A-CED.A.3.

Given a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Given the graph of a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...

This illustrated math lesson plan shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth of a gram....

Based off of the hit television show NUMB3RS, this lesson shows students a real-world application to matrices and matrix operations. Framed in the context of a stolen painting which the thief may hide at different warehouses, students...

This site provides a specific example of Cramer's Rule. The site does not explain why Cramer's Rule works, yet does a fair job of expressing the method to reach the answers.

Ten problems present practice using problem-solving with linear systems in real-world situations. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...

In this activity, students use Computer Algebra System (CAS) tools to find intersections of linear and non-linear equations. They confirm their answers by graphing the equations on the calculator.

This Computer Algebra System (CAS) activity encourages students to investigate addition, subtraction, and multiplication of matrices. They find the inverse of a matrix. Students also solve a set of linear equations by using matrices.

This lesson introduces students to Activity Center and is intended to help students develop the conceptual understanding of how to identify functions as linear or nonlinear and contrast their properties from tables, graphs, or equations.

The student will represent linear inequalities using equations, tables, and graphs. The student will solve linear inequalities using graphs or properties of equality, and determine whether or not a given point is a solution to a linear...

The heptathlon consists of 7 athletics events. Looking at a heptathlete's current performance in these events, how should she plan her training schedule? This activity examines the maths behind the heptathlon's scoring system, and is...
