This document outlines activities for a lesson on positive and negative numbers. The lesson will include reviewing previous concepts, watching two videos about positive and negative integers in real life, an activity where students embody positive and negative numbers in a game, practicing adding and subtracting positive and negative numbers, and reflecting on working with positive and negative numbers with or without a calculator. The goal is for students to deepen their understanding of positive and negative integers and how they relate to the real world.
