Unit 1 · Lesson 6: Estimate Irrational Numbers

Objective: I will use estimation to approximate the value of an irrational square root.

Vocabulary Steps:

Square Numbers (Perfect Square): the result after

multiplying an integer by itself

Irrational Numbers: the set of all numbers that

cannot be written as a ratio of two integers; it

cannot be written as a simple fraction because

the decimal is non-terminating and non-

repeating

0.101101110... , �^23 ,π,√ 10 ,√1.6,−√ 123

Square Root: the square root of a number is a

value that, when multiplied by itself, gives the

number

1. Determine if the number is a perfect square.


2. If not, find the perfect square immediately
   above and below the number.


3. The answer will be between the square roots
   of these two numbers.


4. Estimate the decimal based on how close your
   number is to each of the squares
