Section 8 of the practice tests from The Official SAT Study Guide begins with problems about sets of integers, linear equations with radicals, and geometric angles, among others. Sal solves each problem in quick succession, demonstrating...

Modeling quick thinking and efficient problem solving, Sal works through the linear equation in problem 1 in just over 30 seconds. This video, which covers problems 1-5 on page 530 of The Official SAT Study Guide, also shows students how...

Using pie graphs and multiple variables, Sal carefully (yet efficiently) moves through problems 5-8 of this practice SAT session (page 839 from The Official SAT Study Guide). Both beginning and advanced mathematicians will appreciate...

Another SAT practice test from The Official SAT Study Guide is the focus of this video, which starts out with simple problems involving integers, factoring, perimeters, and percentages. Students will appreciate the relative ease with...

Price increases in real life aren't enjoyable, but Sal's enthusiasm and easygoing explanation makes the question on increasing prices on the practice SAT fun! Showing students how to easily work through problems involving the Pythagorean...

Putting the finishing touches on this practice session, Sal takes students through an algebra problem involving percentages (or decimals, as he prefers) and a geometry problem with equilateral rectangles. Students who need a little more...

The final problem in this section of the SAT practice test involves converting fractions to percentages to find the correct answer. Short and sweet, this video would be a great addition to a class that only has a few minutes to spare.

There are two Khan Academy videos on representing numbers as decimals, percents, and fractions. This one shows students how to represent a fraction as a decimal and a percent. Sal demonstrates the process used to convert the fraction 7/8...

Geometry and algebra are equally represented in this video, which covers problems 10-14 on the practice SAT. As always, Sal is the expert of quick, efficient ways to solve problems - especially helpful for students who have a difficulty...

Create a benchmark. Pupils view key benchmark fractions and their equivalent decimal and percentage representations. The video shows the family of fractions of halves, thirds, fourths, fifths, eighths, and tenths. For each fraction,...

Determine simple percents. A helpful video shows the process of calculating the percentage relating one number to another. Using the method, pupils work several problems within worksheets to gain a better understanding of the skill.

Complete a quick conversion. Pupils view the short video to learn the process to convert a decimal to a percent. The scholars then practice the skill with two worksheets, giving them a chance to better understand the concept.

What was the original? Scholars learn how to find the whole when given the percent and the part in a percent problem. Eager learners use their skills to respond to several questions on a worksheet.

Solve two-step percent problems with a single multiplication. By reviewing how to find the percent of a problem, the video introduces the idea of finding multipliers to find solutions for increasing or decreasing percent problems. Pupil...

Increase or decrease the value. Individuals learn how to determine a new value after being either increased or decreased by a percent. Pupils then practice their skills using a worksheet that covers the concepts.

Know these four and be fine. Scholars learn how to calculate any percentage, all by knowing four easily calculated percents. Two worksheets provide opportunities for learners to refine their skills.

How much did it change? The presenter works two problems to demonstrate how to calculate percentage loss and increase. Pupils have one learning exercise to practice similar problems on their own.

Take a look at the percentage of fractions. Mathematicians learn two different methods to convert fractions to percents. Using two worksheets, classmates practice the methods to determine when one method works easier than the other.

The percent is just a fraction of what the whole used to be. The resource uses the definition of percents to convert percents to fractions. Pupils then use the worksheets to practice the skill.

Make a simple conversion. The short resource provides a description and demonstrates the process of changing percentages to decimals. Two worksheets provide pupils the chance to practice the skill.

Fractions and percentages are just as useful as ratios. An educational video describes how to express ratios as either fractions or percentages. It looks at several real-world examples to adequately cover the topic, including ratios that...

Serve up a rate of percents. The Math at the Core resource investigates the percent of daily value of sodium and saturated fats in different foods. Pupils determine the number of serving sizes they eat of popular snack foods and...

Fifty percent off can still be quite expensive. Future consumers watch a video showing an irresponsible young shopper overspending in a 50 percent off sale. They then use store ads to calculate 10, 25, 50, and 75 percent discounts on items.

Things are so expensive these days. A two-part video explains the concept of inflation and its ties to the federal nominal interest rate. Pupils then use data on the historical prices of items to calculate the inflation rates for several...
