Sophia: Roots and Fractional Exponents: Lesson 4

Teach cube roots by building on an understanding of square roots. The third installment of a 25-part series asks learners to solve simple quadratic and cubic equations using roots. Scholars compare square roots and cube roots throughout...

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...

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.

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 preparing to take on more challenging algebra work.

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...

In this lesson, students are shown the relationship between roots and fractional exponents (one can be rewritten as the other). It is 2 of 10 in the series titled "Roots and Fractional Exponents."

In this lesson, students are shown the relationship between roots and fractional exponents (one can be rewritten as the other). It is 3 of 10 in the series titled "Roots and Fractional Exponents."

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.
