Common Core Standards and Extended Standards
8.NS.1 Know that there are numbers that are not rational, and approximate them by rational numbers.
Extended Standard: Apply and extend previous understandings of numbers to the system of rational numbers.
NS.68.4a Solve real-world problems involving positive and negative numbers (e.g., temperatures, elevations, distance from a fixed point (map reading)).
NS.68.5a Recognize the effects of multiplying and dividing with negative numbers (e.g., -2 × -4 = 8).
NS.68.4b Solve problems involving positive and negative numbers using a number line (e.g., temperatures, distances from a fixed point).
NS.68.5b Recognize that the absolute value of a rational number is how far it is from 0 on the number line (i.e., plot a number and its opposite on a number line and recognize that they are equidistant from zero).
NS.68.4c Locate a given positive or negative number on a number line.
NS.68.5c Recognize that addition means move to the right and subtraction means move to the left on a number line.
8.EE.2 Use square root and cube root symbols to represent solutions to equations. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that the square root of any non-perfect square or non-perfect cube is irrational.

Student Objectives
I can classify numbers.
I can sort rational and irrational numbers.
Given a number, I can place it in the correct subsets of real numbers.
