Cube root of a non-perfect cube
Most people in today's world feel that since calculators can find square roots, that children don't need to learn how to find square roots using any pencil-and-paper method. So even though your math book may totally dismiss the topic of finding square roots without a calculator, consider letting students learn and practice at least the "guess and check" method. Since this method involves squaring the guess multiplying the number times itself , it uses the actual definition of square root , and so can be very helpful in teaching the concept of square root. Square that, see if the result is over or under 20, and improve your guess based on that. Repeat this process until you have the desired accuracy amount of decimals. It's that simple and can be a nice experiment for students!

The fact that squaring and square roots are inverses is explored geometrically and numerically. Finally a powerful method of calculating square roots that produces answers to any desired accuracy quickly is shown. This unit deals with the geometrical measuring of square roots and cube roots and methods of calculating them when a scientific calculator is not used. Squaring a whole number gives the area of a square with that length of side. The inverse, finding the square root, gives the side length of a square with given area.
