Texas Instruments: Estimating 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...

Root for your pupils to learn about roots. Young mathematicians first review the meaning of squares and square roots. They then use this knowledge to simplify square roots of monomials with variables.

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...

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...

Use Glencoe's Math Course 2 randomly generated self-checking quiz to test your knowledge of estimating square roots. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click 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.
