Potentially three lessons on adding and subtracting negative numbers (74 slides long). Initially introduced using inverse operations and number tiles this lesson then goes on to focus on the number line and direction of movement. I have included a model of rising and falling hot air balloons for students who need a concrete image.

I have included comments on some slides to explain what i was thinking whilst planning these lessons and all answers are included.

Happy to receive feedback and hop that you find useful.
