subtracting integers

This learning resource focuses on subtracting integers using two main methods: modeling on a number line and the 'adding the opposite' rule. The document explains that subtracting a positive integer results in a leftward movement on the number line, while subtracting a negative integer moves you to the right. It introduces a systematic approach for subtracting integers, illustrated through the Keep, Change, Opposite method. Examples and guided practice problems provide opportunities for students to apply these methods, reinforcing concepts through various scenarios including real-world applications such as temperature changes and financial transactions. Additional exercises are included to promote independent practice and critical thinking about common misconceptions in integer subtraction.
