Exploring the Celestial Neighborhood

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

With 30 problems, each accompanied by a blank graph, pupils get thorough practice solving systems of equations by graphing and finding the point of intersection. Answers are provided in coordinate form.

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Systems of equations and inequalities model contextual situations. A set of 12 lessons build a solid understanding of writing and solving systems of equations and inequalities using a variety of methods. The module is the fifth in a...

There is no substitute for checking the solution. A short introduction to the substitution method of solving systems of equations is an ideal resource for algebra classes. The slides present steps for the substitution method and...

Two of the strategies for solving systems of linear equations are represented in this foldable: substitution and elimination. Learners solve three examples of each. 

Now that budding mathematicians have figured out linear systems, its time to try nonlinear! A video tutorial outlines the steps of solving a linear-quadratic system of equations. The instructor demonstrates each step of the process using...

You can eat a solar cell? A unit on solar energy begins with a discussion about organic solar cells, followed by directions on how to build your own. After following the teacher's directions to build an anthocyanin...

Here is a fantastic, educational handout packed with information and facts not only about the planets in our solar system, but also regarding major moons and their surface features, dwarf planets, comets, and asteroids.
