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
1.1 $\frac{8+\text{15}}{\text{20}}$ = $\frac{\text{23}}{\text{20}}$
1.2 $\frac{3+4}{6}$ = $\frac{7}{6}$ = 1 $\frac{1}{6}$
= 1 $$
1.3 $\frac{6+\text{20}}{\text{24}}$ = $\frac{\text{26}}{\text{24}}$
1.4 $\frac{5+\text{12}}{\text{15}}$ = $\frac{\text{17}}{\text{15}}$ = 1 $\frac{2}{\text{15}}$
First change all to improper fractions
1. Calculate by first finding the common denominator (smallest common multiple) :
1.1 $\frac{2}{5}$ + $\frac{3}{4}$

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).
