Lesson MOVIE (FLASH) Integers. Adding and Subtracting Integers Game. Adding and Subtracting Integers Card Game. Last year my students had their usual struggles with adding and subtracting integers at the beginning of the year (this is not just a middle school problem).
So I used a game I found online called Twenty Five, where students would draw from a regular deck of cards and add them to a pile, trying to reach a target sum of 25. Red cards were negative and black cards were positive, and each new card would be added to all the ones put on the pile before it. Presumably students were writing down each addition problem they did. It was a waste of time: it was hard to monitor whether students were adding correctly during the game, and difficult for students to keep track of and add up 10, 15 or 20 numbers quickly.
