Several examples of equations in slope-intercept form are the focus of this video. Instructors who are reviewing slopes and functions with their math classes, or who are introducing the concept for the first time, will appreciate Sal's...

Give your students the edge on their upcoming SAT with this video, which covers algebraic and linear equations. Math students who have a hard time transitioning between skills would benefit from seeing Sal do so.

Sal takes your class’ newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems in which mathematicians need to understand how to use linear function graphs.

Young mathematicians will appreciate Sal's careful - yet efficient - methods for solving these typical SAT problems. He takes care to explain problems 8-12, but gets cut off in the middle of problem 12 (to be continues in the next video).

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...

Choosing the "quick and dirty" method of solving problems rather than more mathematically complicated, Sal shows students the importance of time management when taking the SAT (or other math tests). He still arrives at correct answers,...

Picking up where he left off (problem 17), Sal demonstrates graphing functions with an informative and clear explanation. Additionally, problem 18 involves finding the values of angles in an equilateral triangle.

Working through problems 11-14 on the practice SAT, Sal shows students how to solve problems that look complicated, but can actually be quite simple. Problems involving algebraic expressions and geometric distances make up the rest of...

Continuing his lessons on the practice SAT, Sal takes students through problems 10-13, which involve absolute value, comparing angles in a geometric diagram, and finding the median number in a set of consecutive integers. Students will...

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.

Helping students realize the common missteps in solving the average SAT problem, Sal creates a lens through which students can clearly see the correct and incorrect approach to each type of problem. He points out what a student might...

Starting a new set of SAT practice problems from The Official SAT Study Guide (page 518), Sal takes students through some straightforward questions involving basic algebra and functions. However, as every math teacher and student knows,...

Fans of algebra, geometry, and hamsters will enjoy this video, which finishes this practice test with problems 15-16. Sal carefully, methodically, and efficiently takes students through the necessary steps for solving increasingly...

A potentially scary equation ends this practice session. However, it is no match for Sal's mathematical prowess. And once they watch him make the complicated methodology simple, your students will feel more confident in their own...

Problems 17 and 18 finish up this practice session, making this a short and easy video to show in class if necessary. Sal demonstrates how to translate word problems into algebraic expressions to both ease understanding and save some...

Pupils draw the graph of a door opening and closing over time. They graph a given function on their calculators, create a table of values and interpret the results by telling if the door is opening or closing and evaluate the average...

Transitioning between algebra and geometry is no problem for Sal as he deftly solves these practice SAT problems. Mathematicians who have a hard time moving between skill sets will appreciate the way that Sal addresses each new problem...

This worksheet set starts out with three warm-up problems on limits. Then there are review problems for evaluating limits at a point, one and two-sided limits, and indeterminate forms as well as problems to review evaluating limits at...

Greg Kelly puts together another great slide presentation to demonstrate ways to combine derivative rules to evaluate more complicated functions. This pattern is called the chain rule.  He shows step by step ways to solve these...

Compose discounts to find the final discount. Pupils investigate compositions by first looking at numerical representations of multiple discounts taken on a product. Learners develop functions for each discount and compose them to...

Your learners will explore the idea that not all functions have real numbers as domain and range values as seen in this real-life context. Secondly, the characteristics required for a function to have an inverse are explored including...

One in, one out is what functions are about in a video explaining the rules and qualities of these relationships. Have your learners practice with ordered pairs, tables, mapping, and graphs, deciphering whether or not those relationships...

This video tutorial does not include narration, but great math music. It describes how to evaluate a function for a variable through example, and procedure. This would be a great clip to assign as homework for learners just beginning to...

In this functions worksheet, students solve 70 short answer questions. Students find domain of functions and evaluate them for a given value. Students determine if a mapping diagram represents a function.
