Gifted and Talented Math
Mr. Schwab, Mr. Weiskind, and Mrs. Harvey
Unit 2: Math Around the House
The students will be able to:
· Recognize that the opposite of the opposite of a number is the number itself.
· Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane.
· Recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
· Find and position integers and other rational numbers on a horizontal or vertical number line diagram.
· Find and position pairs of integers and other rational number on a coordinate plane.
· Understand ordering and absolute value of rational numbers.
· Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram.
· Write, interpret, and explain statements of order for rational numbers in real-world contexts.
· Understand the absolute value of a rational number as its distance from 0 on the number line.
· Interpret absolute value as magnitude for a positive or negative quantity in a real-world situation.
· Distinguish comparisons of absolute value from statements about order.
· Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers.
· Represent addition and subtraction on a horizontal or vertical number line diagram.
· Describe situations in which opposite quantities combine to make 0.
· Understand p + q as the number located a distance from p, in the positive or negative direction depending on whether q is positive or negative.
· Understand subtraction of rational numbers as adding the additive inverse, .
· Apply properties of operations as strategies to add and subtract rational numbers.
