The Number System
The goal 
Know that there are
numbers that are not rational, and approximate them by rational numbers.


8.NS.1. Know
that numbers that are not rational are called irrational. Understand
informally that every number has a decimal expansion; for rational numbers
show that the decimal expansion repeats eventually, and convert a decimal
expansion which repeats eventually into a rational number.

8.NS.2. Use
rational approximations of irrational numbers to compare the size of
irrational numbers, locate them approximately on a number line diagram, and
estimate the value of expressions (e.g., π^{2}). For example, by truncating
the decimal expansion of √2, show that √2 is between 1 and 2, then between
1.4 and 1.5, and explain how to continue on to get better approximations.
