This tutorial from WyzAnt reviews how to evaluate expressions that contain exponents. An interactive calculator is provided to help students practice.

Nonlinear systems are solved using the algebraic methods of substitution and addition/subtraction. Learn how these methods work through detailed examples.

[Free Registration/Login may be required to access all resource tools.] This lesson covers solving systems with substitution when there is no or infinitely many solutions.

An explanation of what the Substitution Augmentation Modification Redefinition Model (SAMR) Model is, and how it can be integrated with Bloom's taxonomy, as well as technology. Includes an extensive collection of slideshows, videos, and...

An explanation of the Substitution Augmentation Modification Redefinition Model (SAMR) Model. The author uses an analogy of making coffee at home as opposed to having one at Starbucks, and compares this to reading a book versus reading...

This online exercise is for practicing the substitution of third person pronouns for the direct or indirect object of a sentence. English translations guide the student in the first exercise. Incorrect responses are corrected.

Great exercise for practicing the substitution of the pronoun for the direct object of a sentence. The direct object is in bold print, and incorrect responses are corrected.

This online exercise is for practicing the substitution of the pronoun for the indirect object of a sentence. Also practices conjugating the verb correctly in the present indicative tense. An English translation prompts the student to...

[Free Registration/Login may be required to access all resource tools.] Students write net ionic equations for double-replacement reactions that produce precipitates, gases, or molecular compounds, write net ionic equations for...

Students will learn about the different types of mutations and how they work. They will compare the effect of these different types of mutations in DNA, including nucleotide substitution, nucleotide insertion, and nucleotide deletion....

[Free Registration/Login Required] In this Flipchart, students are introduced to linear equations, substitutions, and graphing linear equations on a coordinate grid system.

This site is designed to be a supplement for students of organic chemistry. Its tutorials and self-grading tests are interactive and extremely helpful.

A version of the "20 Questions" game. The instructor tells the class he is thinking of something that starts with, for example, /b/. The students have to come up with what the teacher is thinking of.

This StudyCards stack enables students to review concepts in algebra, arithmetic, and geometry, in preparation for the Math A Exam held in New York. They solve problems involving scientific notation, factoring, linear equations, rate of...

In this activity, students use the calculator to graph the solution to a second-order and third-order differential equations. They convert higher order differential equations by substitution to a system of first order differential...

Students learn to solve a system of linear equations (2 equations with 2 variables) by substitution and elimination methods. They also review the definitions of consistent (independent and dependent) and inconsistent systems, and...

Based off of the hit television show NUMB3RS, this lesson is best used to serve as a preliminary introduction to coding and encryption. Messages are ciphered by single-letter substitution, and the lesson guides students into deciphering...

Ideas for using Symbolic Math Guide (SMG) to help you learn to solve indefinite integration problems. The key transformations in SMG are substitution and integration by parts.

In this chemistry lab, students will investigate a single replacement reaction while also using knowledge of molar ratios to determine percent yields.

This page from Wikipedia, a free and open-source encyclopedia, covers how to solve a variety of trigonometric equations, most of which involve substitution with a trigonometric identity. The identities themselves are not covered, but...

The guided inquiry activity enables students to identify the five basic types of reactions - synthesis or composition, decomposition, combustion, single replacement and double replacement. Students will also begin to predict the products...

The purpose of this lesson is to help young scholars apply math concepts of solving systems of equations to real life situations. The students will use the three methods of graphing, substitution, and elimination to solve the system of...

This online exercise is from the Colby College for practicing the substitution of pronouns for the direct and indirect objects of a sentence, and for using the two pronouns together in the same sentence. A brief English introduction...
