Comparing fractions, it is just not the same as comparing whole numbers. The video starts with fractions with common denominators and moves on to comparing fractions that are not as obvious. Scholars learn two techniques, cross...

The teacher defines and writes a list of the different categories of numbers. But sometimes it's hard to keep all that organized. So she draws a diagram and explains further how the categories of numbers compare or relate to each other....

Game theorists will love the challenge proposed in this video. Every player has the same information (common knowledge) and must guess the closest whole number that represents 2/3 of the average of all numbers other players guessed.

A few examples of numbers, whole, mixed fraction, and decimal, that can be written in fraction form to prove they are rational numbers.

Get a clearer picture of working with fractions. While continuing to work with fractions as parts, the video shows how to use drawing to compare and add fractions. Worksheets then provide opportunities for pupils to practice comparing,...

Provide a more traditional approach. The video introduces the more traditional approach to multiplying multi-digit numbers—using the column method. Pupils watch the presenter multiply by one-digit, two-digit, and three-digit numbers for...

What exactly is the difference between Celsius and Fahrenheit? Watch this video to find out. Sal identifies and defines the Celsius and Fahrenheit scales, assesses the differences, and then labels boiling and freezing on each of the...

Which team has the advantage? An imaginary story about a game of dodgeball in the lost city of Atlantis demonstrates the ways to compare two quantities. One coach compares the ratios of the numbers of players on each team while the other...

Develop ratios within sporting games. Class members watch a video about dodgeball and see how coaches compare the scores. Pupils then work with ratios to compare the scores throughout the tournament. Using their knowledge of ratios, they...

Using a visual means, this video explores comparing ratios. This is a terrific way to approach the topic since it is a difficult concept for learners to understand. It is worth showing to the whole class, every mathematician can benefit...

In this thought-provoking video, Sal shows how a typical linear scale is different from a logarithmic scale. He plots numbers on both scales and compares them to show why the logarithmic scale is useful. This video gives an intuitive...

Can you tell, algebraically, if three lines are parallel? In this video, Sal demonstrates how to rewrite linear equations in slope-intercept form and compare the slope of each line.

Sal defines a hyperbola's vertex and foci in this video and shows how to locate both. By comparing the hyperbola to an ellipse throughout the video, the listener sees the similarities between these two conic sections. This approach makes...

Going deeper into the concept of the Federal Funds Rate, this video guides viewers through the process of inter-bank lending, much like the previous video (Banking 14). Sal's easygoing approach is straightforward and enjoyable to watch.

More carbon dioxide exists in the atmosphere than ever in human history. An informative video introduces the topic of global warming as part of a larger playlist. It looks at possible causes such as Earth's orbit, Earth's moving axis,...

Video lesson shows how to compare the whole numbers 394 and 397 using a symbol. [2:04]

In this lesson you will compare the value of the digits in a whole number by representing the number with models and using your knowledge of place value. [6:48]

The video compares whole number place values. It offers links to other lessons.
