This document introduces square roots by defining what they are, providing examples of perfect square roots from 1 to 25, and discussing principal square roots and related vocabulary. It also covers estimating square roots and using a number line to visualize the relationship between consecutive integers and their square roots.

9. More on the integers…
• Note: Two consecutive integers are
two numbers that follow each other.
• Examples of two consecutive integers:
• 1 and 2
• 12 and 13
• 999 and 1000
• Here is what it would look like on a
number line:

• Note: Two consecutive integers are
two numbers that follow each other.
• Examples of two consecutive integers:
• 1 and 2
• 12 and 13
• 999 and 1000
• 9 and 10 make sense because they are
consecutive integers.

10. Let’s look at this on a number
line.
