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...

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...

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...

By working through word problems involving subtraction, using numbers in the hundreds, the instructor uses visual cues to help viewers understand how to solve the problem. The instructor's method for solving the problem involves graphics...

Looking at large numbers can intimidate many young mathematicians. Use Zoe's place value machine to help learners understand the meaning behind each digit in a whole number. After learning about the ones, tens, and hundreds places,...

What do musicians and mathematicians have in common? Compositions! Learners review function composition in the previous video in a series of 29, and expand that review to include the domain of the composition. The instructor uses...

Young mathematicians may solve for cubic units but do they know what that is? This video does a great job of visually explaining not only how to find cubic volume, but what it means in relatable terms. 

Can you predict what will happen more than 850 years in the future, down to the exact date? Scientists and mathematicians know exactly when specific asteroids will pass near us or possibly hit us. The video explains how they track the...

Take away any hesitation about using a great resource. Young mathematicians watch a YouTube video that covers how to add and subtract linear expressions. Thankfully, it first explains what algebraic linear expressions are to build base...

Scale up a lesson on similarity. Young mathematicians watch a video that investigates the sides of similar figures. They see how to calculate missing sides from the given measures using scale factors.

Speed up your learning of distance, rate, and time problems. Future mathematicians view a video to review how to determine distance, rate, or time, given the other two quantities. They watch as the narrator works through several examples.

Relationships can be good or bad, but functional relationships are the best! The video demonstrates relationships in a table or graph and what makes their qualities functional. Have your learners review functions and then go through a...

Third example's the charm. To learn about simplifying expressions, young mathematicians watch a short video that shows how to simplify an algebraic expression using several properties of exponents.

Toothpicks are as good a manipulative as any. Young mathematicians view a short video that introduces a toothpick puzzle. By moving one toothpick, they must produce a correct equation from an incorrect one.

Scholars' knowledge of probability depends on whether they watch the useful video. Young mathematicians view a short video to learn about the probability of dependent events. The narrator works through several examples to ensure viewers...

It's all relatively simple. Young mathematicians learn about relative frequency by watching a short video. They see how to first determine relative frequencies, and then how to use these values to solve real-world problems.

You'll want to make sure the lesson actually happens. Young mathematicians watch a video to learn about the probability of an event not happening. They see how subtracting the probability of the event happening from one gives the...
