Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

How do you solve linear equations? Learn how to solve simple linear equations by applying properties of equality in this instructional slideshow. The materials include step-by-step instructions and key concepts to support understanding.

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

One step equations involving addition, subtraction, multiplication and subtraction.  Step by step methods of how to solve these equations and has practice problems for each operation.  Answers are provided.  As a...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

Although only 4 slides long, this brief presentation summarizes how to balance equations very clearly.  There is an example of how to balance equations incorrectly, followed by some rules and guidelines that show the correct...

How do you solve a problem when a symbol or letter is used in place of a missing number? Build algebraic reasoning and problem solving skills with this presentation that explains three methods for finding a missing variable. The guess...

Introducing exponential equations means learners need to take all the rules and tricks they learned for exponents and actually apply them. This presentation comes to the rescue by touching on changing bases in exponential...

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...

Eliminate the obvious. A series of slides presents algebra classes with step-by-step procedures for solving systems of equations using the elimination method. It provides an introduction to the elimination method for...

The process for balancing chemical equations is stepped through slide by slide in this presentation. For some strange reason, the subscripts for certain elements are not dropped down on the first slide only, so you may want to copy the...

Show your class all the hard work you have put into their lesson by showing this PowerPoint presentation. They will not only be proud of you, but it will help them solve multiplication and division word problems using the algorithms.

The example of two travelers meeting somewhere along the road has been a stereotypical joke about algebra as long as algebra has existed. Here in this detailed presentation, this old trope gets a careful and approachable treatment....
