Ways of counting in local languages and different cultures


To describe and illustrate various ways of counting in local languages and different cultures throughout history [LO 1.2]

Now you are going to explore the world of number names and symbols to see how our number system developed.


1.1 You have been using numbers and counting on and counting backwards. See if you can remember the names for the numbers in some of our South African languages. In the table below write the name of a local language most commonly used in your area. Now write in the words in that language for numbers 1 to 10.

Numbers English ………………………. Afrikaans
1 One Een
2 Two Twee
3 Three Drie
4 Four Vier
5 Five Vyf
6 Six Ses
7 Seven Sewe
8 Eight Ag
9 Nine Nege
10 Ten Tien


When children learn to count, they chant the numbers and move rhythmically to the music. Get together with some friends and make up a rap song to count from 11 to 20 in any South African language. Present this song to the rest of the learners.

1.3 Now write number names of another local language most used in your area. Also write the name of the language in the space provided in the second column.

Numbers Other local language Numbers Other local language
11 16
12 17
13 18
14 19
15 20

1.4 Try to find out the names for the following numbers and write them in the correct columns:

Numbers Other local language English Afrikaans
1 000
10 000

CHECKLIST: Number names

Yes No
1.1 I have written in number names for 1 to 10 in a local language that is used most in my area.
1.2 I have made up a rap song to count from 11 to 20 with my friends. We performed it for the rest of the learners.
1.3 I have written in number names for 11 to 20 in a local language that is used most in my area.
1.4 I have found out and written in the names for 100; 1 000 and 10 000.


You may do this in your own time, at school and/or at home, as your educator decides.


(Research is when you need to look up information and use it to answer questions. Ask your educator to take you to the library to do the research in this section or use the computer to look up information on the Internet.)

READ: The following information tells you about counting systems. Now test your skills by answering the questions that follow.

2. Pre-history: People in ancient times

Thousands of years ago, before people could write, they had no knowledge of numbers and figures and they had to find ways of indicating how many animals or possessions they had. They put a small pebble in a bag for every animal they possessed, or carved notches on a stick.

  • Why did people start to need numbers?
  • Draw a stick with notches carved on it to show that the owner possessed 5 sheep.

2.3 Besides carving notches on a stick, what else did they use to show how many animals they possessed?

Ancient civilizations

3. The Babylonians

Many years later, people used signs or symbols to represent numbers. The Babylonians who lived in Mesopotamia made wedge-shaped notches in wood or pressed such marks into damp clay tablets.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
