This unit standard does not replace any other unit standard and is not replaced by any other unit standard. |
PURPOSE OF THE UNIT STANDARD |
This unit standard is for people who solve realistic and abstract problems in which it is appropriate to make comparisons in terms of differences and ratios. People credited with this unit standard are able to estimate and calculate solutions to applied problems and computations. People are recognised for their ability to express the problem situation using words, mathematical expressions, equations and/or drawings, devise and implement strategies to solve mathematical problems and interpret, verify and justify solutions in terms of practical considerations. |
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |
'Demonstrate and apply understanding of the number system';
'Solve realistic and abstract problems involving whole numbers, fractions, decimals and percentages'. |
UNIT STANDARD RANGE |
Problems involve those where it is necessary to compare quantities using differences and ratios.
Any one of the quantities involved in the situation may be unknown and the numbers may be whole numbers or fractions expressed as fractions, decimals or percentages. Fractions can be expressed as simple fractions, percentages or decimals. |
Specific Outcomes and Assessment Criteria: |
SPECIFIC OUTCOME 1 |
Estimate solutions to applied problems and computations. |
ASSESSMENT CRITERIA |
ASSESSMENT CRITERION 1 |
1. Estimates are reasonably close to the exact figures as can be justified within the context. |
ASSESSMENT CRITERION 2 |
2. Estimates chosen facilitate easy calculations. |
ASSESSMENT CRITERION 3 |
3. The accuracy of estimates is justified by the context, need for speed and purposes of estimating. |
SPECIFIC OUTCOME 2 |
Express the problem situation using words, mathematical expressions, equations and/or drawings. |
ASSESSMENT CRITERIA |
ASSESSMENT CRITERION 1 |
1. Mathematical symbols are correct and used in the proper context. |
ASSESSMENT CRITERION 2 |

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: |
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here. |
