The Football Number Line Volume 2 is a great way to work with adding positive and negative numbers. It is an interactive lesson that you need a whiteboard with a projector to play. This lesson promotes teamwork, technology, and reinforcement of adding integers. It not only focuses on integers but offers the flexibility of incorporating the skills needed for basic math, pre-algebra, and algebra. It is a great way to involve some of those hard to reach students. This is a great review game in prep
