Negative Integers Overview

Lesson 1: Introduction to Negative Numbers. By the end of the lesson, students will (a) reason about the symmetry of positive and negative integers around 0, and (b) place positive and negative integers on number lines using the ideas of order, symmetry, 0 is a number on the line, multiunit interval, and unit interval.

Lesson 2: Using Symmetry. By the end of the lesson, students will be able to apply the principles of symmetry, order, and multiunit to (a) evaluate the order and placement of positive and negative integers and (b) add positive and negative integers to lines marked with a multiunit interval.

Lesson 3: Symmetry and Estimation. By the end of the lesson, students will be able to apply the principles and definitions of symmetry, order, unit interval, and multiunit interval to place numbers on the number line using estimation.

Lesson 4: Ordering and Comparing Integers. By the end of the lesson, students will be able to apply principles of order and symmetry to (a) order positive and negative numbers on and off the number line, and (b) write mathematical expressions comparing numbers using < and >.
