INTRODUCTION
The learning programme for grade six consists of five modules:
1. Number concept, Addition and Subtraction
2. Multiplication and Division
3. Fractions and Decimal fractions
4. Measurement and Time
5. Geometry; Data handling and Probability
COMMON AND DECIMAL FRACTIONS (LO 1; 2 AND 5)
LEARNING UNIT 1 FOCUSES ON COMMON FRACTIONS
You have to work in groups of three for this activity. Ask your educator for the paper that you will need. Read the questions attentively and show the operations that you use for calculating the answers:
1. Mrs Samuels buys one third of a metre of pink material and five sixths of a metre of purple material. How many metres of material does she have to make cushions for her class?
2. The Jansen family is picnicking. If Dad eats a quarter of the food, Mom eats three eighths of it and Sarah two eighths, will there be any left for you to eat?
3. The Grade 6 learners have been asked to establish a vegetable garden at the school. If they plant half of the garden with carrots, two sixths with potatoes and one twelfth with spinach, what fraction of the whole garden has been planted?
4. Because they have worked so hard in the garden, the classes are rewarded. The 6A class drinks four and one fifth litres of cold drink; the 6B class drinks five and four tenths litres of cold drink and the 6C class drinks three and two thirds litres. How many litres of cold drink did the school provide for the learners?
5. Explain how your group calculated the answers to the rest of the class.
6. Compare your methods. How do they differ?
Assess your work on a scale of 1 - 4 by circling the appropriate number:
1 = not at all 2 = just a little 3 = good 4 = outstanding

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.
Assessment Standard 1.8: We know this when the learner estimates and calculates by selecting and using operations appropriate to solving problems that involve:
1.8.3 addition and subtraction of common fractions with denominators which are multiples of each other and whole numbers with common fractions (mixed numbers);
