Pre-Algebra Unit 1: Number Sense
Learning Target 4 Guided Notes
 We have learned that ________________________________ are numbers that can
not be written as the ratio of 2 numbers (cannot be written as fractions)
 These types of numbers we have learned create decimals that DO NOT
terminate and DO NOT Repeat. Thus we cannot find an EXACT location for
them on a number line wince we will never know how to round them correctly
since we will not know what the next number in the decimal is.
 We can estimate where we may find them on a number line by using
______________________________________.
 __________________________________________ is when we use rational numbers
that we can find on the number line to approximate the location of irrational
numbers near them. WE usually do this to an accuracy of the nearest tenth or
hundredth.
