SWBAT students will find the absolute value of an integer by using the number line and correctly reading the problems in the independent practice.
LEQ: How do I determine the best numerical representation (pictorial, symbolic, objects) for a given situation?
NC.6.NS.5 Understand and use rational numbers to: • Describe quantities having opposite directions or values. • Represent quantities in realworld contexts, explaining the meaning of 0 in each situation. • Understand the absolute value of a rational number as its distance from 0 on the number line to:• Interpret absolute value as magnitude for a positive or negative quantity in a realworld context. •Distinguish comparisons of absolute value from statements about order.
NC.6.NS.6 Understand rational numbers as points on the number line and as ordered pairs on a coordinate plane.a. On a number line: • Recognize opposite signs of numbers as indicating locations on opposite sides of 0 and that the opposite of the opposite of a number is the number itself. • Find and position rational numbers on a horizontal or vertical number line.
