On a cold morning, a seven-year-old will happily read the car’s outside temperature aloud, without knowing what the number means. This 2nd grade Celsius and Fahrenheit thermometer worksheet shows where that number comes from. Every thermometer lies on its side, with a bulb on the left and a scale from 0 to 70 along the top. A worked example explains three steps and shows 15°C. Then six thermometers follow, some in degrees Celsius and some in Fahrenheit. Your child finds where the red line stops and writes the temperature on the line below. A second page gives the answer key.
