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
** Activity 19 is a task for the portfolio. The assignment is fairly simple, but learners should complete it neatly and accurately. They must be informed in advance of how the educator will be assessing the work.
DECIMAL FRACTION | ÷ 10 | ÷ 100 | ÷ 1 000 |
0,3 | 0,03 | 0,003 | 0,0003 |
0,9 | 0,09 | 0,009 | 0,0009 |
0,45 | 0,045 | 0,0045 | 0,00045 |
3,48 | 0,348 | 0,00348 | 0,000348 |
1,02 | 0,102 | 0,0102 | 0,00102 |
0,368 | 0,0368 | 0,00368 | 0,000368 |
2,041 | 0,2041 | 0,02041 | 0,002041 |
2.1 one position to the left
2.2 two position to the left
2.3 three position to the left
1. A CHALLENGE!
Form groups of three for this exercise. Use exactly the same numbers as in 3.1 and first divide them by 10, then by 100 and finally by 1 000. (You may make use of a pocket calculator).
Complete the table:
DECIMAL FRACTION | ÷ 10 | ÷ 100 | ÷ 1 000 |
0,3 | |||
0,9 | |||
0,45 | |||
3,48 | |||
1,02 | |||
0,368 | |||
2,041 |
2. See whether you are able to complete the following sentences:
2.1 When we divide a decimal fraction by 10 the decimal comma is shifted
TIME FOR SELF-ASSESSMENT
It is important to be sure that you understand the work done so far. Show to what extent you have mastered it by reading the criteria and colouring the appropriate face.
Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.
Assessment Standard 2.2: We know this when the learner describes observed relationships or rules in own words;
Assessment Standard 2.3: We know this when the learner determines output values for given input values, or input values for given output values, using:
2.3.3 tables.
