Inflation - things get more expensive

Unit standard(s): 9014

Summary:

This activity introduces the concept of inflation, and gives learners the opportunity to discover for themselves that prices go up over time. It allows learners to realise that not all items increase in price by the same amount over a fixed period of time. The ideas of simple and compound interest are also introduced.

Inflation revisited

Unit standard(s): 9014

Preparing budgets

Unit standard(s): 9014

Summary:

This activity is designed to be used as an assessment activity. It is intended to recap principles that have been learnt in the first 5 activities. There is an opportunity for learners to make their own judgments about how a business develops and to draw up a budget accordingly. If time allows it may be worthwhile for learners to share their budgets with each other, explaining the reasons behind their decisions.

Additional sales

Unit standard(s): 9014

Summary:

In this activity we look at an alternative source of income for a salon. The aim of the activity is to allow learners to think through the requirements of producing a gift pack for sale. Learners should realise that decisions that are made can have far-reaching effects on a business’s profits. Many decisions not only have direct economic consequences but may, for example, affect the image of the salon which could also influence the profits of the business.

Reading statements and budgets

Unit standard(s): 9014

Summary:

In this activity we want learners to gain an understanding of how to read budget statements. This is because many of the later activities in this unit relate back to budget statements. We start by asking learners to reflect on their own personal income and expenditure statements. Two budget statements are included with the activity: one is for a hair salon and the other is the national income and expenditure statement. It is important for learners to recognize the similarities that exist between all budget statements.

The client questionnaire

Unit standard(s): 9015

Summary:

This is a preliminary activity designed to raise some of the issues involved in data collection. Students will collect their own data, using possible clients in the hairdressing industry as a context, and reflect on it. In order to locate this in a bigger context, an information handout has been included that defines some common statistical terms and ideas. Potential problems such as sample size and representativeness are introduced.

The salon appointment book

Unit standard(s): 9015

Summary:

This activity involves the organisation and representation of data using a pie chart and bar graph. Students use data to answer questions and to determine the different central tendencies of the data. The salon appointment book is used as a data source.

Fridays are always busy?

Unit standard(s): 9015

Summary:

This activity involves reading information from tables. Students explore what information can be obtained from a table of data and what sorts of conclusions can be drawn. They use numbers to back up an argument and present a comparative bar graph to illustrate their conclusions. The context is the interpretation of the monthly figures for visits to the hair salon.

Reading the newspaper

Unit standard(s): 9015

Summary:

This activity involves more reading and interpretation of data tables. Students study newspaper tables with figures comparing the South African elections of 1994, 1999 and 2004. They make comparisons and present a comparative bar graph to illustrate their conclusions. The activity is self-contained and suitable for evaluation purposes as it draws on ideas and terminology from previous activities.

Trends and connections

Unit standard(s): 9015

Summary:

In this activity students interpret the range and distribution of data. They extend the idea of determining ‘the centre’, to the idea that there are patterns and important connections between certain variables that can also be measured. They examine variance from the mean and identify outliers as well as trends. They identify correlations and use a line of best fit to make simple predictions.

Reading and predicting

Unit standard(s): 9015

Summary:

In this activity students read data and make predictions by analysing trend lines. They observe patterns and measure important connections between variables. They identify variance from the mean as well as outliers, suggesting what implications these may have in real life situations.

Beauty Africa Exhibition

Unit standard(s): 9015

Summary:

In this activity students analyse data and use it to make decisions and plans. Tables and pie charts are used and information is given as percentages which students use to calculate actual numbers. Problems relating to transferring data and contamination of data are raised.

What are my chances?

Unit standard(s): 9015

Summary:

This activity introduces the idea of probability. A preliminary handout has been included with background information on some of the common applications and terminology used in this branch of statistics. The students work with single events in the context of the ‘Lotto draw’, comparing ‘counted’ results with calculated probability. In this way they work with the mathematical verification of experimental results.

Combined events

Unit standard(s): 9015

Summary:

In this activity students move from probabilities involving single events, to probabilities of combined events. They work with the multiplication principle and are introduced to the ideas of dependent, independent and mutually exclusive events.

Manipulations and misunderstandings

Unit standard(s): 9015

Summary:

In this activity students critique the ways that data is used to support arguments. They identify how data is manipulated and how one can be misled by incomplete statistics, inappropriate samples and graphical methods.

Unit standard(s): 9016

Summary:

This activity deals with painting the salon and estimating the amount of paint needed. We use the floor plans from Activity 2 to calculate the surface area to be painted.

Getting the co-ordinates right

Unit standard(s): 9016

Summary:

This activity deals with the International Colour Code for hair colouring. We look at the co-ordinates used to describe colour combinations. The first co-ordinate is the natural colour and the second co-ordinate is the fashion (tone/reflect) colour.

Attending an exhibition

Unit standard(s): 9016

Summary:

This activity deals with reading maps and train timetables. We determine the best route to get to an exhibition from our salon. We then work out the time taken to travel this route by car and train. We also determine the cost of both modes of transport.

Assessment: Attending an exhibition

Unit standard(s): 9016

Summary:

This activity uses the same context as Activity 7 but our salon is much further away from the exhibition. This activity can be used for assessment.
