1. Grade 8: Math Course 3 STUDENT VERSION
Ch 9-1 BConvert Temperatures
Prerequisite 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 temperatures
between 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) + 32
Score 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) + 32
Score 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.

The student, without help, understands that the actual weather
remains the same regardless of whether a Fahrenheit or Celsius scale
is usedto measure the temperature, and can understand the
correlation between the two scales. 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

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) + 32
Score 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.
