Help algebra learners relate a real-life function that happens at the Oakland Coliseum every time the Raiders play. The resource states that the revenue of the Oakland Raiders home games is a function of the number of seats sold and the...

Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

Sal continues showing examples of finding the inverse of the function. Here he shows a subtle, but important technique of taking the negative square root of each side of the equation when solving for the inverse because of the...

Sal continues looking at function inverses in this video by showing two examples. In each example, he finds the inverse and shows the graph of both functions. Both of his examples are with linear functions, but his first example shows a...

Sal shows an example of finding the inverse of the parabola with a restricted domain. He alludes to a reason behind the restricted domain but leaves the reason for it up to the listener to determine.

Sal uses a real life example of exam scores to instruct the class on calculating an average. He further demonstrates how to calculate what future scores would be needed to attain a desired average score by the end of term.

A good explanation for blossoming mathematicians, this video explains the difference between average and central tendency, as well as arithmetic mean, median, and mode. Those who haven't grasped these concepts in algebra or those who are...

Continuing his conversation about data sets from the previous video, Sal introduces range, variance, and standard deviation as means of dispersion. Those who are advancing in algebra or who are beginning a statistics class will benefit...

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts out with an intuitive sense of what a function inverse is. He then, using an example, shows how to find the inverse of a function and also shows how...

What a find! Here is a lesson, designed to meet sixth grade math Common Core standards, that focuses on the calculation of different measures of center for the scores from a penalty shoot-out competition. An independent...

Fourth graders explore the mass and length of peanuts by pretending to parent a peanut. In this mode, median and range lesson students graph their measurements and then use them to find the mode, median and range. Students discuss peanut...

Problems 6-7 on page 396 of The Official SAT Study Guide are covered in this video, which includes both strategies for solving the equations and finding the answer in a multiple choice question. The problems in this video range from...

On problems 5-8 of the practice SAT video series (page 424 of The Official SAT Study Guide), Sal demonstrates several different ways to solve each problem in an efficient and timely manner. Students will appreciate the ways he details...

Sal again makes the SAT look effortless, and yet students will follow his mathematical processes with ease. Problems range in difficulty, from basic algebra equations to more complicated geometric figures.

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...

Advising students to become comfortable with the 30-60-90 triangles as an SAT prep skill, Sal finishes this review session with a geometry problem, an algebra problem with fractions, slopes, and median numbers. His tips and test-taking...

Sal picks up the pace in this video, going through problems 1-7 on page 774 of The Official SAT Study Guide. Basic algebra, arithmetic, and geometry problems start out this section, allowing students to build up some steam before hitting...

Students collect data about energy usage and use mathematical calculations to analyze their data. In this energy conservation and statistics math lesson, students survey their homes to complete an energy usage worksheet. Students...

Some students enjoy math problems as "brain teasers," while other students are just trying to get through them. Sal addresses both learners in this video, which shows different ways to approach and solve problems on the practice SAT.

A good explanation for blossoming mathematicians, this video explains the difference between average and central tendency, as well as arithmetic mean, median, and mode. Those who haven't grasped these concepts in algebra or those who are...

On the home stretch of this practice session, Sal completes problems 18 and 19 on page 738 of The Official SAT Study Guide. He begins problem 20, but chooses to finish it in the next video instead of rushing the answer. As always, Sal's...
