Using a dynamic manipulative, students will have a visual for adding and subtracting integers.
This model is similar to a hot air balloon and provides a way to visualize adding and subtracting integers.
The program displays instructions. The right arrow adds a helium bag to the balloon, and the left arrow adds a sand bag.
The horizontal line represents ground level. The balloon’s vertical position is displayed at the bottom of the screen.
