So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

Falling off a bridge might not sound like your idea of a good math problem, but incorporating the final scene of Les Misérables is sure to spark interest. The goal is to use the time Javert fell off the bridge to determine how high he...

A baseball trajectory and a parabola seem to make the best pair in real-world quadratic applications. Here is a current baseball resource with questions, discussions, and explorations regarding a quadratic function and home run...

What makes this resource special? The amazing answer key that comes with worked out solutions and notes for each problem. Practice problems include all topics ranging from linear systems to simplifying exponential expressions. The packet...

Starting with the basics, learners discover the features of a parabola and the ways to accurately graph it. After pupils practice with graphing, the end of the learning exercise focuses on application type problems. 

Starting with a point (focus) and a line below the point (directrix), in this video, Sal tries to find the set of all points (locus) equidistant to the point and the line. He shows, using the distance formula, that indeed, we have an...

Sal first solves a couple of equations using the factoring method he has already taught. Next, he introduces the quadratic formula and demonstrates how to plug the numbers from the quadratic equation into the quadratic formula....

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

Solving quadratics by factoring is the main concept in this video. Several examples are shown with positive numbers and with negative numbers. The instructor demonstrates how to set the factored equation to zero to solve the quadratic....

Starting with a point (focus) and a line below the point (directrix), in this video, Sal tries to find the set of all points (locus) equidistant to the point and the line. He shows, using the distance formula, that indeed, we have an...

Learners practice generating parabolas with a motion sensor while determining the vertex form of the equation. They compare it to the regression equation from the calculator onto a data mate software. Each student completes several...

After making a correction to the last problem in his previous video, Sal explains how to graph quadratic functions. Those who have a hard time with the concept of graphing algebraic functions will find Sal's instruction and easygoing...

Though Sal expects that viewers are "reasonably familiar" with square roots, he takes this opportunity to explain some of the notation, and how to graph square root functions. He uses a graphing calculator from my.hrw.com/math06 to...

If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Explaining that the only thing he gets in return for these videos "is the satisfaction of you guys getting a perfect score on the SAT," Sal charges on through the practice SAT problems. Students who have a difficulty with parabolas and...

Graphing skills are a focus of this video, making it ideal for students who have a hard time using slopes and functions. Additional problems involve visualization, geometric figures, and algebraic factoring.
