10. LOGICAL SEQUENCE AND COMPARISON OF DECIMAL FRACTIONS

10.1 Work together with a friend and compare the results of the following athletes.

Put the athletes in order from the winner to the last place.

10.2 a) Find the following statistics of five of your class mates and complete the table:

b) Arrange names of your friends from the shortest to the tallest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

c) Now arrange names of your friends from the heaviest to the lightest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

10.3 Fill in:<;>or = :

a) 0,63 …… 0,7

b) 0,4 …… 0,39

c) 32,068 …… 32,102

d) 1,27 …… 1,270

e) 0,007 …… 0,07

f) 4,44 …… 4,044

Assessment

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 1.3: We know this when the learner recognises, classifies and presents the following numbers in order to describe and compare them:

1.3.2 decimal (to at least three decimal places), fractions and percentages;

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 2.3: We know this when the learner represents and uses relationships between variables in a variety of ways using:

2.3.3 tables.

Learning Outcome 5: The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.7: We know this when the learner identifies the largest and smallest scores in a data set and determines the difference between them in order to determine the spread of the data (range).
