5. REVIEW AND CORRECTION OF HOMEWORK (suggested time: 10 minutes)
Homework provides an opportunity for teachers to track learners’ progress in the mastery of mathematics concepts and to identify the problematic areas which require immediate attention.
Therefore it is recommended that you place more focus on addressing errors from learner responses that may later become misconceptions.
6. INTRODUCTION (Suggested time: 10 Minutes)
Activity 1
Divide the class in groups and give the learners the following terms to define in their own words. Let them share their definitions with the class. Clarify any misconceptions or wrong definitions. Write the most cprrect definitions on the bord for the learners to copy in their notebooks.
profit, loss, discount, VAT,
budgets,
accounts,
loans,
simple interest,
hire Purchase en
exchange rates
Activity 2
Use suitable examples an let the learners do problems dealing with the following: a) calculating of percentage if the amount is known. b) Calculating an amount if the percentage is known c) Calculating the original amount if the new amount is given and a given percentage is deducted. d) Calculating the original amount when a certain percentage is added.
Note: With problems in financial context learners must know how to work with percentage and decimal numbers.

Teaching activities
Learning activities
(Learners are expected to :)
Work through the following activities with learners:
Activity 1 a) A shop owner gives 30% discount on CDs. After the discount you have to pay R 105. What is the price for a CD without the discount?
Engage in the class discussion based on the activities b) A shopowner buys a dining room suit for R3 999 and sell it at a loss of R300. i) Calculate the percentage loss. ii) What must he charge if he wants to make a profit of 15%? c) Sipho buys a fridge that cost R4 499. He does not have the full amount to pay for the fridge. The shop offers him a hire purchase deal. He has to pay R 400 deposit and a montly payment of R 273 over a period of two years. If the monthly payments go into arrears, the shop will repossess the fridge. Sipho will thus lose all the money he paid so far. i) Calculate the total amount that Sipho will have to pay for the fridge after the two years? ii) How much more will Sipho pay for the fridge than the original price? iii) Give your answer in (ii) as a percentage of the cash price. d) The latest range of Spiderman winter pyjamas will cost € 8.50 per item. If the Rand-Euro exchange rate is R 11, 36 to € 1, how much will you pay for the pyjamas in Rands?

9. CONSOLIDATION/CONCLUSION & HOMEWORK (Suggested time: 5 minutes) a) Emphasise that:
cost price is the amount a dealer pays when he buys an article from a producer or manufacturer without VAT and profit.
the price marked is the price of the product after VAT and profit was added.
interest is the money you owe when you borrowed money or the money you get if you made an investment.
the discount on an article is always less than the marked price of the article.
hire purchase is a way of buying goods by paying for the item with interest added over a period of time
exchange rate is the market value by which of one currency is exchange for another b) The primary purpose of Homework is to give each learner an opportunity to demonstrate mastery of mathematics skills taught in class. Therefore Homework should be purposeful and the principle of ‘Less is more’ is recommended, i.e. give learners few high quality activities that address variety of skills than many activities that do not enhance learners’ conceptual understanding.
Carefully select appropriate activities from the Sasol-Inzalo workbooks, workbooks and/or textbooks for learners’ homework. The selected activities should address different cognitive levels.
