Negative integers, absolute value
Slope-Intercept Form Battleship
Battleship in math class. Taking it in a slightly more advanced direction, lets make a 4 quadrant Battleship grid. And lets require kids to write equations in slope-intercept form, graph them, and develop a strategy for this process. (Putting equations in point-slope would be a great substitute if you want one.)

Integers card game: The red cards are negative and the black are positive. Each player starts with 6 cards, drawing one at the beginning of their turn and discarding one at the end. The goal is to play pairs that equal 6 or -6. The person playing 3 pairs first wins. The other players add the absolute value of their cards to get a score. The goal is to have the lowest score at the end of the game.
