Integer Operations and Models

The video introduces two models for integer addition: the chip model and the number line model. The chip model uses manipulatives like colored chips or beans to visually demonstrate addition, emphasizing that opposite integers add to zero. Examples include adding negative and positive integers using this model. The number line model involves moving a creature along a number line to represent positive and negative steps, reinforcing the concept of opposites and absolute value. The video provides examples for both models, demonstrating how to add integers effectively.
