Khan Academy: Intro to Square Roots

A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase...

What is the square root of 100? Sal explains what the square root of 100 is, but he needs a little help explaining why. Note: This concept can be challenging for some. If you are showing this video to your class, it does not stand alone....

Introducing square roots into the quadratic equation mix, Sal addresses the ways viewers might solve the problems, both correctly and incorrectly. The video is an integral step in not only Sal's algebra series but also in developing math...

Sal works through several problems involving rational and irrational numbers, and shows how to find the difference. This video is a good stepping stone for those who are preparing to take on more challenging algebra work.

Explains what square roots are and demonstrates how to find the square root in an equation. [5:24]

By watching this video lesson, students will learn the meaning of cube roots and how to find the cube root of a negative number. [8:00]

If your class has a grasp of square roots, but is having difficulty with the product property of square roots, this video might be for you! In the video, an instructor completes a short proof of the property, defines the property, and...

Before defining the quotient property of square roots, the teacher in this video works through an example that shows how the property is possible. She then goes through a couple more examples of the property in action. Show this resource...
