This item contains a 24 card game of "I have, who has" cards. It has temperatures in Fahrenheit only and contains temperatures that are counted in different intervals. For example, either by 2, 3, 5, 10, 20, 50. Some of the thermometer temperatures are not exactly on a number (For example, the temperature may be half way between the numbers). Some of the thermometers have increment marks between the numbers, so that not all marks have a number.
