Building from concrete (pictorial) to abstract (computational), this multi-day lesson teaches integer addition with a combination of whole-class and small-group inquiry, culminating with a game called Attack & Defend. It introduces a new pictorial representation of integers, combining the best of the number lines and algebra tiles approaches.
