Practice Estimating Square Roots

Strengthen your number sense with Practice Estimating Square Roots! This playsheet helps you learn how to approximate square roots by comparing each number to the closest perfect squares. You’ll discover how even irrational numbers can be estimated quickly and accurately using smart strategies — no calculator required!

You’ll begin by reviewing common perfect squares such as 4, 9, 16, 25, and 36. These “anchor numbers” act as key reference points that help you determine the approximate value of square roots like √7, √20, or √33. Seeing how each number fits between two squares builds confidence and understanding.

Next, you’ll practice estimating by deciding which perfect square your number is closer to. By comparing the distances, you’ll learn whether the square root should be rounded slightly up or down. This step-by-step reasoning strengthens your ability to judge magnitude and compare values accurately.
