# 4.2 Language, calculations and time  (Page 2/2)

 Page 2 / 2

The shapes should preferably be duplicated on manilla, but if this is not available, use ordinary paper.

## Activity: language, calculations and time [lo 1.2, lo 1.4, lo 1.8, lo 1.9, lo 1.10, lo 2.2, lo 4.1, lo 4.2]

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 .

## 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 1.2: 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.

how can chip be made from sand
are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey
Giriraj
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius
Alexandre
what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
