Develop a formula based upon numerical computations. The 31st part of a 33-part unit has the class determine the formula to convert a temperature in Celsius to a temperature in Fahrenheit. They do this by making comparisons between the temperature scales. Learners use the formula to convert temperatures and to determine when the two temperatures have the same value.

Concepts

Instructional Ideas

• Use the formula and convert from a temperature in Fahrenheit to a temperature in Celsius
• Employ a similar process to convert between Celsius and Kelvin

Classroom Considerations

• The temperature conversions may fit 8.F.B.4 better than 8.EE.B.5

Pros

• Teacher notes provide sample pupil responses to the discussion questions
• Answer keys show the computations used in the conversions

Cons

• The problem set seems disjointed from the lesson; it contains a problem that has nothing to do with the conversion of temperatures
