The Number System
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., π2).
8.EE.1
Know and apply the properties of integer exponents to generate
equivalent numerical expressions. For example, 32 &times; 3–5 = 3–3 =
1/33 = 1/27.
8.EE.2
Use square root and cube root symbols to represent solutions to
equations of the form x2 = p and x3 = p, where p is a positive
rational number. Evaluate square roots of small perfect squares
and cube roots of small perfect cubes. Know that √2 is irrational.
