Using and Transforming Formulas

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. 

While there are many types of equations to solve, the main focus here is on quadratics. Starting with a quick review of the different methods, learners are guided through the solving process and are challenged to solve higher level...

I'm a fan of clearing the denominator, but solvers can also find common denominators and cross multiply to solve the linear equations on the worksheet. Each of the six problems has rational coefficients.

Not all linear functions are linear transformations, only those that go through the origin. The third lesson plan in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at...

Perfect as a review guide, this worksheet provides a range of questions focusing on functions. Topics include composing functions, transformations, domains, and polynomials. Also included are corresponding worksheets focusing on other...

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since variables are on both sides of the equation, it is important to verify the answer by...

The instructor demonstrates how to use the distributive property to eliminate fractions in an equation. Remember to have learners plug their answers into the original equation to check their work.

Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since there are variables on both sides of the equation, it is important to verify the...

The number of basic algebraic properties can become overwhelming for learners. A lesson plan explains and gives examples for all the basic algebraic properties. The resource is perfect to use as a way for pupils to...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or...
