Square Roots And Real Numbers

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...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions. 

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...

Try out a resource using triangles to estimate radicals. An interactive app allows learners to approximate some irrational numbers involving square roots. They find the two consecutive numbers that an irrational number lies between...

You have been given a square root and need to compare that to a decimal number to find out which one is bigger. How can you make that comparison? One way to do this is to find the square root of the square root number and then compare it...

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...

The instructor demonstrates how to find the square root of a fraction. She simply explains that you separate the numerator and denominator, meaning you find the square root of the numerator, and then you find the square root of the...
