**Course Description**

Students taking Occupational Math compute with rational numbers . Students
use ratio and

proportion and formulas to solve problems. In each topic area, students solve
application

problems.

3. Compute with proportions

4. Apply computational skills to application problems

**1. Compute using rational numbers**

Criteria - Criteria - Performance will be satis factory
when :

o learner writes intermediate computation steps when solving generic rational
number (add,

subtract, multiply, divide: fractions, decimals, and percents) problems.

o final answer to a generic rational number problem is written to the tolerance
specified with

each question. (Example: " Round answer to nearest tenth of an inch.")

o learner successfully answers 80% of all questions.

o learner completes test within scheduled class period.

Conditions for Assessment - Conditions - Competence will
be demonstrated:

o Student may not use the Math Review textbook while taking quizzes and tests.

o Student may use pencil, blank paper, calculator, and 1/2 page of notes for all
chapter tests.

o In chapter tests.

**Learning Objectives**

a. Convert among different fraction forms (common, improper, mixed).

b. Compare relative size of given fractions.

c. Use "multiply top times top bottom times bottom" idea to multiply fractions
together.

d. Use "invert and multiply" idea to divide fractions.

e. Add and subtract fractions by putting fractions in common denominator form .

f. Explain decimal positional notation system.

g. Convert decimal to fractions and vice versa.

h. Round decimals to specified place value.

i. Convert decimal to a specified fractional value (ex: to the nearest 64th or
nearest 32nd.)

j. Compute with decimals using the four basic operations.

k. Solve basic word problems using decimal computational skills.

l. Convert among fractional, decimal, and percent form.

m. Identify the components of generic and word percent problems. Part, Base,
Rate

n. Solve percent problems by determining components known and solving for the
component

to be found.

**2. Compute using formulas.**

Criteria - Criteria - Performance will be satisfactory
when:

o learner demonstrates understanding of a given formula's variables by
substituting given

values into the correct position in the formula.

o answer is written to the indicated precision.

o answer is written with the correct unit of measure.

o student completes quiz/unit test with an 80% or higher score.

Conditions for Assessment - Conditions - Competence will
be demonstrated:

o when learner completes unit test.

e. Determine the purpose of each variable and constant in a formula.

f. Substitute known values into the formula.

g. Evaluate the formula with calculator using the Order of Operations.

h. Express answer to the required accuracy with the correct units of measure.

i. Discuss how to obtain a reasonable estimate for the answer that can be used
to check the

final computed value.
