Simplifying Square Roots

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...

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude, rise,...

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...

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...

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...

Think outside the box and use an engaging, interactive app that shows the relationship between square roots and squares using an actual square. Pupils find that moving a slider increases the side length of a square and its associated area.
