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 $\frac{2}{3}$
1.2 $\frac{\text{13}}{\text{20}}$
1.3 $\frac{5}{8}$
1.4 $\frac{2}{3}$
If you know how to simplify and to apply it correctly, you will soon realise that it is a helpful aid when calculating with fractions. It can help you multiply, divide, add and subtract more easily (and quickly). You will also find it easier to fill in relationship signs. Let’s have a look at how you manage.
1. Simplify the following:
1.1 $\frac{\text{10}}{\text{15}}$
1.2 $\frac{\text{26}}{\text{40}}$
1.3 $\frac{\text{45}}{\text{72}}$
1.4 $\frac{\text{42}}{\text{63}}$
2. LET'S PLAY A GAME!
You'll need a partner and two dice.
When we wish to do addition with fractions, the denominators have to be made similar.
Eg. $\frac{1}{3}$ + $\frac{3}{6}$
$\frac{1}{3}$ = $\frac{2}{6}$
$(\frac{2}{6})$ $\frac{1}{3}$ + $\frac{3}{6}$ = $\frac{5}{6}$
What you know about determining equivalent fractions will be useful when you do this.
When the sum of two fractions is calculated, only the numerators are added together. The denominator is retained as it is.
If the answer is an improper fraction, you have to convert it to a mixed number.
Learning Outcome 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.
Assessment Standard 1.5: We know this when the learner recognises and uses equivalent forms of the numbers listed above, including:
1.5.1 common fractions with 1-digit or 2-digit denominators.
