You mean the square root of five and five don't have the same value? Learners estimate the value of irrational roots. As they practice estimating the value, they increase their understanding of roots. The lesson is the fourth in a series...

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

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...

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....

"The neat thing about completing the square is that it will always work," Sal explains, "no matter how crazy the problem is." A basic overview of how to complete the square, this video provides a good background for both beginning and...

Take a radical look at square roots. The presentation examines square roots as the lengths of the sides of a square with a given area on the coordinate plane. Using this method, it is clear why the square root of a number can be positive...

Students explore the concepts of square roots and exponential expressions. In this square root and exponential expression lesson, students complete an investigation called Building A Square Patio. Students use color tiles to develop the...

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.

The Difference Between Two Squares is an algebraic expression where two terms are perfect squares and one is negative. In this clip the Algebra teacher uses the FOIL method to factor a difference between two squares and prove the equation.

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...
