A square root is graphically represented by writing a number underneath a symbol that looks like a check mark. Calculate the square root of a number by figuring out which number times itself equals the original number. Although manipulating square roots is often used in upper level math courses like algebra and calculus, the basic concept of a square root is simple enough for an elementary school student to understand. You can solve simple square roots using math principles that are taught in elementary school.
