How to Approximate Square Roots Without a Calculator

This video tutorial teaches how to estimate square roots of non-perfect squares. It covers identifying non-perfect squares, using a number line to find integer bounds, and estimating square roots to the nearest hundredth. The video explains the properties of non-perfect squares, such as being irrational and non-repeating, and introduces a pattern in the number of non-perfect squares between perfect squares. It also provides a step-by-step method to estimate square roots without a calculator, using a ratio and rounding technique.
