• 1. Grade 8: Math Course 3 STUDENT VERSIONCh 9-1 BConvert TemperaturesPrerequisite Content:Solve equations using the order of operations.Solve and graph one- and two-step equations in one variable.Use exponents and square roots.Solve for any variable in a literal equation (previous lesson).Learning Goal:By the end of this lesson, students will be able to convert temperaturesbetween the Fahrenheit and Celsius scales.More Complex Content:Score 4.0 In addition to Score 3.0 performance, in-depth inferences and applications that go beyond what was taught, such as I know that whether I say the current temperature is 0°C or 32°F, the temperature is the same and these are just two different ways to describe the same amount of cold needed to freeze water. I understand this no matter which set of degrees are given. Score 3.5 I understand how cold or warm the weather is whether someone describes the temperature to me using the Fahrenheit scale or the Celsius scale.Score 3.0 While engaged in solving conversion tasks from Celsius to Fahrenheit and Fahrenheit to Celsius scales, the student demonstrates an ability to without help, solve word problems to convert temperatures from Fahrenheit to Celsius or Celsius to Fahrenheit using the correct formula. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32 The student exhibits no major errors or omissions. Score 2.5 I can, without help, solve a Fahrenheit/Celsius conversion problem using the appropriate formula and get the right answer. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32Score 2.0 No major errors or omissions regarding the simpler details and processes, such as
• 2. I don’t need any help to choose the correct formula, and I don’t need help to begin solving the problem. Sometimes, I make mistakes when I am trying to multiply or divide by fractions or decimals. However, the student exhibits major errors or omissions with Score 3.0 elements. Score 1.5 I can find the correct answer using the correct formula if someone is there to help me, but without help I make mistakes. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32Score 1.0 With help, a partial understanding of some of the Score 2.0 elements and some of the Score 3.0 elements. If someone helps me, I can choose the correct formula to use, but without help, I get mixed up and often choose the wrong formula to use. Score 0.5 I know the formulas to solve temperature conversion problems are on the FCAT reference sheet. I know where to find them; but I don’t know which formula to use or how to use them. I need help.Score 0.0 Even with help, no understanding or skill demonstrated.

For example, 0°C and 32°F are two ways to describe the same amount of cold needed to freeze water. Score 3.5 The student, without help, can correctly identify what type of weather is associated with any degrees on both the Fahrenheit and Celsius scales, but may not understand how the two scales are correlated.Score 3.0 While engaged in solving conversion tasks from Celsius to Fahrenheit and Fahrenheit to Celsius scales, the student demonstrates an ability to without help,correctly solve the problem when it is presented in a word problem format, using the appropriate formula. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32 The student exhibits no major errors or omissions. Score 2.5 The student can, without help,correctly solve a Fahrenheit/Celsius conversion problem using the appropriate formula. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32
• 4. Score 2.0 No major errors or omissions regarding the simpler details and processes, such as without help, the student can correctly identify the appropriate conversion formula needed to solve the problem, and without help, the student can begin to solve a temperature conversion task, but will make a common error(s) preventing a correct solution, such as incorrectly solving problems when decimals or fractions are used. However, the student exhibits major errors or omissions with Score 3.0 elements. Score 1.5 The student with help can solve a temperature conversion problem using the correct formula. C = (F – 32) ÷ 1.8 F = (C × 1.8) + 32Score 1.0 With help, a partial understanding of some of the Score 2.0 elements and some of the Score 3.0 elements. The student, with help, can identify the correct temperature conversion formula to select to solve a problem for the Celsius or the Fahrenheit scale. Score 0.5 The student can find the formulas on the FCAT reference sheet, but cannot determine the correct formula to use.Score 0.0 Even with help, no understanding or skill demonstrated.
