Bonnie en Tommie het baie Engelssprekende maats en wil graag leer om in Engels te tel. Kom ons help hulle.

Coco, the clown, handed out balloons. Here he is with Bonny’s balloons.

  • Do all the operations on the balloons. Write the answers on the balloons in Coco’s left hand. Colour in each balloon lightly as you complete the operations. Double the answers on the balloons.
  • Help Bonny and Tommy to set these clocks correctly. The clocks are 1 hour and 10 minutes slow .
  • These clocks are 15 minutes fast.
  • Here is Coco with Tommy’s balloons.

Do all the operations on the balloons. Write the answers on the balloons in Coco’s left hand again. Colour in each balloon lightly as you complete the operations. Halve all the other answers except those on H, because there you need the whole line for the answer.

  • Calculate:
  • Divide these 2 shapes into 8 equal parts (eighths).
  • Use your multiples’ chart in Module 2 and practise counting forwards and backwards in 8’s until the 10th multiple.

You will notice that you already know more than half of the multiples:

  • Complete the sequence and say what you have done:
  • Draw a circle around all the even numbers and a block around all the uneven numbers :

1229 1006 1040 1445 1238 1441

1544 1500 1337 1002 1223 1335

  • Arrange the even numbers from the least to the most :
  • Arrange the uneven numbers from the most to the least :
Number: Rename: Regroup:
1237 = _____+_____+_____+_____ = _____+_____+_____+_____ 1058 = _____+_____+_____+_____ = _____+_____+_____+_____ 1304 = _____+_____+_____+_____ = _____+_____+_____+_____
  • Write the number names of the above numbers:



  • Here is Coco with Terry’s balloons.

  • Do the operations on the balloons. Write the answers on the balloons in Coco’s left hand. Colour in the balloons lightly as you complete the operation. Make each answer 12 more .


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 1.2: We know this when the learner knows number names from 1 to at least 10 in the mother tongue (if not the language of learning and teaching) and one other local language;

Assessment Standard 1.4: We know this when the learner orders, describes and compares numbers;

Assessment Standard 1.8: We know this when the learner can perform calculations, using appropriate symbols, to solve problems;

Assessment Standard 1.9: We know this when the learner performs mental calculations;

Assessment Standard 1.10: We know this when the learner uses the following techniques:

1.10.1 building up and breaking down numbers;

1.10.2 doubling and halving;

1.10.3 number-lines;

1.10.4 rounding off in tens.

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 copies and extends simple number sequences to at least 1 000.

Learning Outcome 4: : The learner will be able to use appropriate measuring units, instruments and formulae in a variety of contexts.

Assessment Standard 4.1: We know this when the learner reads and writes analogue and digital clock time in terms of hours, half-hours, quarters of an hour and minutes;

Assessment Standard 4.2: We know this when the learner solves problems involving calculations with and conversions.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
