Algebra I Teacher Resources

Starting a year of Algebra I? This mighty packet practices all of the major topics with different ranges of difficulty. Standards include everything from linear to quadratic to rational expressions. Use it in a...

Need a helping hand in Algebra I? How about a giant, super-sized instructional activity packet? Here is a resource that has worksheets for virtually every concept with some accompanying examples. 

In this ration & proportion for Algebra I worksheet, students answer twenty-three word problems involving ratio and proportion.

Ninth graders explore applications of Algebra.  In this Algebra I lesson plan, studetns investigate eight applications of algebra ranging form the mathematics of roller coasters to tracking the popularity of a web site.

Many high school science courses rely on mastery of algebra skills. In an integrated chemistry and Algebra II lesson scholars review solving equations for a specified variable with a worksheet. They use common chemistry equations to...

The central concept in this video is solving quadratics by factoring. Several examples are shown with positive and negative numbers. The instructor demonstrates setting the factored equation to zero to solve the quadratic, using a graph...

The instructor continues solving quadratic equations by plugging values into the quadratic formula. These examples are more difficult because the answers do not correspond to whole numbers.

Sal dissects basic algebraic equations of the form Ax=B. He encourages viewers to fully understand the equations before learning how to manipulate them. Furthermore, he teaches students how to solve the equations systematically. The...

This video focuses on an example of unit conversion using drug dosage. Sal, the all-knowing pre-algebra guide, uses a problem from a nursing class to show the process of unit conversion within an algebraic expression. This helpful video...

Sal illustrates more involved equations in this last video in a series. It follows "Simple Equations" and "Equations 2". He continues using color-coded markings to help increase students' understanding of a more complicated equation:...

Sal demonstrates what not to do when simplifying a squared binomial. Next, he clarifies why they can't square each term individually and then add them. He uses his incorrect example as a starting point to demonstrate how to simplify a...

After correcting the last problem in his previous video, Sal explains how to graph quadratic functions. Those with difficulty graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at...

Help your students understand how to use their algebraic reasoning to solve a one-step equation, where they must solve for X. Add this video to a lesson or assign it as homework.

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...

In this video, Sal brings it all together and incorporates the concepts from previous lectures (quadratic formula, multiplying polynomial expressions, radical expressions, exponents). This video would be a great way to end a unit or...

Sal explains that the most significant common factor of any number is the largest number divisible into both monomials and not necessarily the number with the most significant value. He breaks down two numbers into their prime factors as...

First, clarifying that people need to "resist every temptation on earth" when squaring a binomial, Sal walks viewers through a few binomial equations using binomials and applies the skills from the previous videos about working with...

Sal adds a few more steps to these problems as he solves algebraic equations with two steps, though he states that "there's more than one way to do it." Those who become confused by increasingly complicated algebra problems on a test...
