How well can you add and subtract both positive and negative numbers? Temperature Map requires students to add and subtract both positive and negative numbers in specially-designed word problems to determine the temperatures of ten cities around the world. This game serves as an enjoyable way for students to practice adding and subtracting positive and negative numbers, improve number sense, and to learn a little bit about world geography and climate, and each city’s temperature in the game is within the range of its actual normal temperatures in summer or winter.
