These lessons, with videos, examples, and solutions, help Grade 6 students learn about squares and square roots.
Understanding squares and square roots is fundamental in mathematics and has applications in various fields like geometry, physics, and engineering.
What are Squares and Square Roots?
The square of a number means to multiply the number by itself. In exponent form, it will have an exponent of 2.
For example, the square of 4 is 42 = 4 × 4 = 16.
The opposite of squaring a number is finding the square root. Since 42 = 16, the square root of 16 is 4.
In this lesson, we will learn about squares and square roots of perfect squares. A perfect square is a whole number that can be obtained by squaring another whole number.
The following diagram shows how to find the square root of some perfect squares. Scroll down the page for more examples and solutions of squares and square roots.
Non-Perfect Squares and Irrational Square Roots:
If a number is not a perfect square, its square root will be an irrational number (a non-repeating, non-terminating decimal).
√2 ≈ 1.41421356…
√7 ≈ 2.64575131…

Properties of Perfect Squares
- Always non-negative (since squaring a real number never gives a negative result).
- End with specific digits: 0, 1, 4, 5, 6, or 9 (but never 2, 3, 7, or 8).
- If a number ends with an odd number of zeros, it’s not a perfect square (e.g., 1000 is not a perfect square).
