This session delves into the foundational concepts of integer operations, primarily focusing on adding positive and negative integers using visual number lines. The approach is designed to bridge the gap between abstract arithmetic and intuitive understanding through relatable analogies, such as the elevator scenario, where movement is represented as positive and negative steps. Participants will learn to master the number line as a tool for visualizing addition, distinguishing between movements in positive (right) and negative (left) directions. The session provides guided examples and encourages engagement through problem-solving, reinforcing learning goals that include calculating sums with different signs and verifying results logically.
