CONTEXT

15/01 – 17/01

1.       CONVERSIONS

• Conversion factors and tables
• Metric to imperial and vice versa
• ^oC to ^oF and vice versa

2.       TIME

• Time Tables,
• Transport (Bus, Train, Taxi)
• Production e.g. building a house
• Tide

Complex projects in familiar and unfamiliar context.

Examples:

• Determine quantities of materials needed to build an RDP house.

Planning a trip between two places

20/01 –24/01

3.       FINANCIAL DOCUMENTS:

• Loans

• Tax forms

Loans:

• loan agreements (term of loan; interest rate)
• Bank statements: Showing interest rate and monthly repayment changes

Tax:

• Tax deduction tables; Tax rate tables; IRP5 forms; Employee income tax forms

27/01– 31/01

03/02– 07/02

4.       TAXATION

·         Taxable income

·         personal income tax,

·         taxable & non-taxable income,

·         rebates and UIF

Two methods are promoted for this type of calculation:

• dividing the “VAT inclusive” value by 1,15

• identifying the “VAT inclusive” value as being 115% and working out the “value excluding VAT” as 100%.

10/02 – 14/02

5.       TARIFF SYSTEMS: (Compare 2 or more)

• Tables
• Graphs

Formulae

·         Subsistence farming

·         Electricity tariff systems

·         Telephone tariff systems

·         Rental options (e.g. photo copiers, machinery, etc.)

17/02 – 21/02

6.       INCOME, EXPENDITURES, PROFIT/LOSS

• large organisations and fundraising projects

7.       COST PRICE & SELLING PRICE:

• Cost of producing/ manufacturing
• Appropriate selling price
• Percentage profit

8.       BREAK-EVEN ANALYSIS:

determine break-even values from  formulae and graphs

• Running a small business

24/02 – 28/02

9.       DEVELOPING QUESTIONS:

• National and global issues

10.   COLLECTING DATA:

• Develop and use data collection instruments

11.   CLASSIFYING & ORGANISING DATA:

• sort numerical and categorical data using categories and class intervals

tallies and frequency tables

Develop and use an appropriate form/instrument for collecting multiple sets (Grade 12) of data, including

• National and global issues

Collect data on problems being investigated relating to the national and global issues (Grade 12).

Classify collected data as:

• categorical data (e.g. male/female; type of car)

• numerical data, further classified as discrete data (e.g. number of people; number of cars) and continuous data

Sort collected numerical data according to more than two categories (Grade 12).

02/03 – 06/03

12.   SUMMARISING DATA:

• quartiles
• inter-quartile range
• calculate and analyse measures of central tendency and spread
• percentiles

Quartiles and IQR values in conjunction with box-and-whisker diagrams

• percentiles (interpretation only)

09/03 – 13/03

13.   REPRESENTING DATA:

• pie charts
• histograms and bar graphs
• line and broken line graphs
• scatter plots

box and whiskers

In Grade 12, owing to the large and complex nature of the data dealt with in relation to national and/or global issues, it is expected that more complex estimation will

be required

14.   INTERPRET AND ANALYSE DATA:

• identify and describe trends
• identify and describe sources of bias
• answer questions under investigation
• identify and describe any misleading representations and data summaries

Compare different representations of multiple sets of data and explain differences.

Investigate situations in which summarized and/or represented data is interpreted in different ways.
