1. Divide into groups of three. Ask your educator for the required sheets of paper and calculate the following answers WITHOUT making use of a pocket calculator:
1.1 The Johnny family's telephone account comes to approximately R376 each month. More or less how much will they have to pay for a year's use of the telephone?
1.2 Mr Naidoo drives 795 km each month for his work. What is the distance that he covers in a year and a half?
1.3 The Grade 7s are going on a tour and each learner has to pay R499. What is the total amount that the 78 learners will have to pay?
1.4 The "Ride Safely" taxi group transports passengers to a soccer match in Johannesburg, at R245 per passenger. What is the total amount that will be paid if 837 spectators make use of their service?
1.5 An elephant calf weighs 932 kg. How much will 348 elephant calves weigh?
2. Check your answers with the help of a pocket calculator.
3. Explain how you calculated your answers to the rest of the class.
4. Compare the different methods. How do they differ?
Evaluate your work on a scale of 1 – 4 by circling the appropriate number.
1 = needs attention
2 = fairly good
3 = very good
4 = outstanding
