Here is a great real life example of when a person would need to compare numbers. Each of the four examples explains how to compare the numbers beginning with the number at the left and compare the value of each digit. The examples begin...

Use this video to show older elementary mathematicians that they can compare numbers using the same thinking that they did when they were in the first grade. Sal compares decimal numbers using the greater than and less than symbols. He...

A helpful video takes a deeper look at place value by identifying numbers of greater and lesser value using a visual approach. It would be a great way to solidify concepts for those who learn visually. Using bright colors and grouping...

Sal tackles pre-algebra in this series of videos, starting with the concept of negative numbers. Using a number line, he takes the viewer through different practical examples of negative numbers, such as temperature and bank accounts....

What numbers should not be shared? Numbers thoughout history have been banned for one reason or another. The resource provides details of illegal numbers and compares them to the written and spoken word. Discussion brings the idea of...

Sal compares two fractions containing uncommon denominators. He analyzes both fractions using prime factorization. Note: This video may be confusing for learners who struggle or are new to the concept. It would be best used for...

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...

Is math real? Scholars first learn about the Goldbach conjecture and prime numbers as an introduction to the philosophical idea of whether numbers actually exist. The video continues on to use an example of a circle to consider math from...

If the square root of negative one exists, where is it on the number line? A math video presents a geometric representation of complex numbers and the complex plane, and then compares it to the geometric representation of real...

In this video, Sal determines if 30/45 and 54/81 are equivalent fractions. He explains that he looks at each numerator and denominator as two numbers multiplied together. Then he simplifies both fractions to conclude that 30/45 and 54/81...

Use a number line to plot the given points to compare their value. The given numbers in this problem are both negative so remember that whichever number is furthest to the right is the larger value. Watch this short video and see how to...

Two very similar numbers and you have to figure out which one is larger. The teacher diagrams a place value chart and shows you how to write the two numbers to make a comparison.

So you want to put some given values in order from greatest to least? The instructor starts out by drawing a place value chart. She then inserts all the numbers into the chart. This helps you visually see their value so you can compare...

Real mathematicians have mastery of real numbers. Pupils learn about the classification of real numbers by watching a YouTube video. They also see how to compare real numbers and how to determine absolute value.

So you want to put some given values in order from least to greatest? The instructor starts out by drawing a place value chart. She then inserts all the numbers into the chart. This helps you visually see their value so you can compare...

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....

Two fractions with unlike denominators. Compare and figure out which one is greater. There are a couple of ways to do this. This time change the fractions to decimals to compare. Once the values are found, they can also be plotted on a...

Comparing decimals can be easy. Watch and learn how to line up four decimal numbers vertically and then starting from the left, compare each number in each place value to determine which is largest and which is smallest. This procedure...

When you compare integers to determine their order or which is largest, you can plot them on a number line. Duane demonstrates how to use a number line, plot integers, make a comparison, then determine which integer is largest and which...

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...

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,...
