## Activity: to solve in context problems that concern economic issues [lo 1.6]

1. Cash register slips are part of our lives. Wherever we buy and pay, we receive them. Let us take a closer look at a couple of them!

Your educator will provide you with the necessary paper.

Divide into groups of three. Collect at least three till slips from various shops in your area (you may collect more!) and compare them in terms of the following:

1.1

Lay-out: Where is the name of the shop written?

Is there an address? Where is it written?

Is there a telephone number? Where is it written?

Is there a fax number? Where is it written?

1.2 What, in addition to the above, is also indicated on the till slip?

1.3 Are there any similarities between the various till slips? If yes, what?

1.4 Are there any differences between the various till slips? If yes, what?

1.5 Which till slip is "best" according to you? Motivate your answer.

 ASSESSMENT: TILL SLIPS 1 2 3 4 Co-operation with others Does not co-operate effectively Co-operates, but has to be prompted frequently Co-operates, but does not listen to opinions expressed by group members Co-operates beautifully and listens to suggestions made by group members Tidiness and organisation Work is untidy and disorganised Organised, but difficult to read Neat and organised, easily legible Neat, clearly laid out work; easily legible Completeness Fewer than 3 till slips. Not all questions answered A lot of information omitted Only a few questions were not answered Assignment executed completely

CHALLENGE!

Can you solve the following letter sum?

T A K

+ T A K

P O T

Each letter represents a different digit from 1 to 9. Find values for A, K, O, P and T.

(There are 13 possible solutions!)

## Test

1. Complete:

1.1 1 493 + 1 268 = 1 268 + ________________________

1.2 (318 + 469) + 1 426 = 318 + (_________ + _________)

= ________________________ (3)

## 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 1.6: We know this when the learner solves problems in context including contexts that may be used to build awareness of other Learning Areas, as well as human rights, social, economic and environmental issues such as:

1.6.1 financial (including buying and selling, profit and loss, and simple budgets).

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

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
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
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes

How can I make nanorobot?
Lily
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
how can I make nanorobot?
Lily
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
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.
Tarell
what is the actual application of fullerenes nowadays?
Damian
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.
Tarell
