Mathematics teacher’s workshop July 2023

On 28 July 2023, Dr Mokhwetha Mabula and Dr David Johnson a senior lecturer in the department of Economics University of Wisconsin-Madison, Madison WI, in USA were invited to run a Mathematics teacher’s workshop at Mamafubedu Public School in Petrus Steyn, Eastern Free State. Dr Johnson taught mathematics in high schools and participated in training of Mathematics and Economics teachers in USA and he runs several mathematics teachers’ workshop in South Africa during his visit at UP FABI from August 2022 till August 2023, including UPPUA.

The teachers enjoyed the discussion with Dr Johnson and he taught them some new methods on how to solve mathematics problems and also how to inspire their learners to think of the problem in a different way. The school has a mathematics laboratory and it seems that the school takes the study of mathematics very serious. The laboratory has some basic equipment but it could be improved if there is funding available.

The school principal Mr MJ Litabe welcomed the visitors and expressed his intention to turn their school into a mathematics orientated school and expressed his appreciation for the support from the  UP Mathematics department and SARCHi chair support with the training visits to their school.

Dr Mokhwetha Mabula also expresses his thanks to Prof Jacek Banasiak for his financial support and  visits that he attend in person.


Crypto Giants and UTM Mathematics Awareness campaign

On 24 February 2023, Mokhwetha Mabula visited Mamafubedu and Ikaheng secondary schools in Petrus Steyn, in the Eastern Free State for Mathematics career awareness and motivation. The invitation was facilitated by Mr Nhlanhla Mkambula, a teacher from Mamafubedu high school. The discussions we had were successful in both schools and some learners have indicated their interests to pursue a career in Mathematical Sciences. We have recorded the names and contact details of these leaners so that we can keep in touch and track their progress for further interventions or motivation.

I would like to thank the SARCHi Chair and UTM for the financial support to make this initiative a success, Prof Jacek Banasiak and also Mrs Rachel Combrink




Crypto Giants and Thusong Youth Centre

Crypto Giants participated in a youth festival at Brixton multipurpose community in Johannesburg,
which was organized by Thusong Youth Centre and Publik Kreativity Drama Grew based in Alexandra
Township. The event took place on 1 October 2022, where youth from eight South African Provinces
(except Free State) participated in different activities to show case their skills and talents. This was a
great platform for Crypto Giants and UTM to present and introduce the Mathematics awareness
campaign. Most learners/youth really enjoyed the interaction with the Crypto Giants and some were
interested in Mathematics/mathematics related careers.

Crypto Giants would like to thank Mr Stanley Mabaso for the invitation to participate in this event and are
looking forward for future collaborations. 



Crypto Giants and UPPUA Winter holiday school classes July

Crypto Giants participated in winter holiday classes for UP pre-University academy at the  Groenkloof and Mamelodi campuses, helping with Mathematics tutoring for grade 8, 9 and 10.

These extra classes are offered to several schools around Pretoria and the aim is to prepare learners to handle tertiary education by bridging the gap between high school and university concepts. The classes are contact in a unique way, and do not follow the normal day to day of school teaching. In this program learners are encouraged to participate and solve problems on their own, that is, teaching is learner centred.

Crypto Giants and UTM supports and participates in the school initiative that encourages learners to follow careers in Mathematical sciences.

High school Mamafubedu outreach in May

As part of UDM and Crypto Giants school outreach, we received an invitation to visit Mamafubedu
public school in the small town, of the Eastern Free, Petrus Steyn to run a mini workshop for their
Mathematics teachers. The theme of the workshop was mathematics teaching practice, challenges
and opportunities. The other component was on careers in Mathematics with leaners. The workshop
was organized by the School Principal Mr M.J. Litabe and the HOD of the Mathematics.
The school learners are mainly from the township called Mamafubedu and in general do not have
many opportunities available to them. Our visit, played an important role to both learners and teachers.
Hopefully, we will keep in touch with the school and get a few learners who will eventually study
degrees in Mathematical Sciences at the University of Pretoria.
The trip was sponsored by the SARCHi chair in Biomaths of the University of Pretoria, Prof Jacek Banasiak.




3 October Swartklip Combined School

Crypto Giants Saturday Classes
The Crypto Giants (CG) and Under 20 Mathematicians under SARChI have come together in assisting high school students with Mathematics. This project is one of the most successful projects in CG since all its aims and objects were met. The members of CG decided in 2017 to give back to the community and tutored grade 9 learners Mathematics on Saturdays. The school adopted was Thulaganyo Secondary School in Winterveldt. The school is based in a rural area where minimum resources are available. The lack of resources tends to affect an important right, a right to education. We elaborate more on this matter in the next paragraph. The project grew in 2018 as we (CG) decided to tutor grade 8 too. In 2018 we had eight classes, four from each grade. We noted that Thulaganyo Secondary School only offers grades seven to nine. Yet in 2019 we decided to include grade 10 learners who are alumni of Thulaganyo. This proves that the project is continually growing and without any doubt next year we are aiming to go for grade 11. Tutoring at Thulaganyo has been an interesting journey for all CG members. We have learnt the importance of giving back and whilst in the process, fell in love with teaching. As mentioned above, we have a challenge caused by the fact that the background of the learners is not financially stable. As a result, students cannot afford stationery. Mr Zuko Ndinisa, a CG member and tutor, said: “One of the challenges I encountered is that learners have no calculators, that has limited me to giving exercises with only small numbers that are easy to compute without the use of a calculator.” Ms Cylda Masinga, the chairperson of CG and tutor, confirmed the enjoyment of these classes by saying “I am very much grateful for the opportunity to help the learners. I now enjoy teaching Mathematics and interacting with learners”. Mr Nduduzo Majozi, the supervisor of CG and tutor, is the one who tutors grade 10 learners. This class is made up of five neighbouring schools. During the weekend he (Mr Majozi) tasked his learners to research the different branches of Mathematics and Mathematicians. The learners gave positive feedback and also challenged Mr Majozi by saying “We study Mathematics, we are often told the importance of it in terms of careers, but why study these particular topics? Why are we not taught the history of Mathematics? What’s the vision of the syllabus?” Miss Ntombifuthi Khoza, the leader of school projects in CG, will be assisting in addressing these questions and providing full support to grade 10s.

2nd Crypto Giants and SARCHi chair UTM Annual Mathematics day 19 October
The 2nd Crypto Giants and SARCHi chair UTM Annual Mathematics day took place in
the Botany Building. The event catered for learners from grade 9 to 11. The participants came from several
schools in Shoshanguve, Winterveldt, and Delmas.

BIUST Visit 14 October
Our Mathematics Department hosted about eighteen fourth year Botswana International University
of Science and Technology students. The purpose of their visit was to learn more about the Mathematics
postgraduates programmes at UP. They were accompanied by Dr Zechariah Mushaandja. Thank you to
Mokhwetha for his involvement. These Mathematic days seek to encourage and educate learners about careers in Mathematics. There were four invited speakers from industry to talk to learners. Mr Ronsam Erasmus (ABSA), Mr Malibongwe Skhosana (Riskworx), Mr Miles Lesufi (Investec) and Mr Bersan Lesch (Deputy Director: Science Promotion at DST).

10 MAY Crypto Giants visit to South African Reserve bank

In most cases, University students and school learners struggle to understand the use of Mathematics outside the classroom. This is a serious challenge for the Mathematics community as many young people decide to follow other career options except Mathematics. It is clear that we have to find the link and network with private companies to teach and show the students how they use Mathematics in their world of practice. On 10 MAY 2019, Crypto Giants visited the South African reserve bank to learn about the use of Mathematics in Economics and Financial markets. There was an interesting talk from SARB personnel, in particular, the use of Mathematics to model the production of notes and coins. Miss Ntombifuthi Khoza asked an interesting question, which could be the main focus for reserve bank in future, “How does the cashless transaction affect the model”, which did not have an answer or the effects have not to be seen yet. The team was welcomed by Miss Kyalami Dlamini of the Reserve bank.

Crypto Giants coaching Siyanqoba learners at Tshwane University of Technology centre

Crypto Giants and Tshwane University of Technology Mathematics and Statistics department collaborated in 2017 to run the Siyanqoba training centre which is hosted by TUT Shoshanguve campus to train township learners to participate in the National Mathematics Olympiad. At the moment, schools participating are Rethomile primary school, Thulaganyo secondary school, Reitumetse and Hlomphanang high school, with the total number of fourty learners, thirty juniors and ten seniors. This year, sixteen learners from this centre progressed to the second round of the Mathematics Olympiad. We thank our coaches, Miss Ntombifuthi Khoza and Mr Kgaugelo Makgaole for their great job, also the support from SARCHi chairs under twenty Mathematicians and SAMF.We hope to grow this centre and to inspire township learners to participate in mathematics in general.



20 October: Crypto Giants Mathematics day

The Crypto Giants together with SARCHi chair under twenty Mathematicians hosted sixty-five learners from Thulaganyo high school, Tswaing high school from Wintervedlt, Rethomile primary school, Reitumetse high school from Shoshanguve and Future comprehensive from Limpopo province. The learners and their teachers had the opportunity to listen and discuss careers in Mathematics and what Mathematicians do in the corporate world. The theme of the day was “ I am a Mathematician”. The guest presenters were Prof Jean Lubuma (DEAN of NAS), Prof Jacket Banasiak (SARCHi), Dr Maggie Aphane (HOD of Mathematics and Applied Mathematics, SMU), Mr Patrick Rasehwete (SAMF), Miss Nosipho Mathebula (Financial Markets department, Stanlib) and Mr Cliford Malapane (PSG).

Learners were also given the opportunity to write a small test based on their general knowledge and understanding of basic concepts of Mathematics, with winners receiving prizes ranging from UP Mathematics department t-shirts, cups and pens. In 2019, we expect to increase the number of schools participating in Mathematics day. 

4 August: Thulaganyo School 


1. Crypto Giants is still conducting Saturday classes in Winterveldt, 
2. We have two camps in Welkom, with two schools, Lebohang Secondary School and Teto, with 200 and 350 learners respectively. 
9-14 July 
We have partnered with CHPC to conduct hardware courses for grade 11 learners with some of our partner schools in Cape Town
2 March 2019 Thulaganyo high school
It is based in the township called Wintervedlt in the north of Pretoria. This area is one of the poorest townships in Tshwane with high unemployment, that affects the learning and teaching of learners around this area. Crypto giants together with SARCHi chair under twenty Mathematicians adopted this high school to assist with Saturday Mathematics extra classes. In doing so, it became clear that most learners do not have basic tools like calculators. Crypto giants donated sixty-seven scientific calculators to the learners in this school. We hope that this will assist in advancing the learning of these learners and reduce the burden from the teachers, in particular, during the examination period. We like to thank all the people who made this possible by donating some calculators and funds. In particular, we thank Mr Vuyisile Rodolo and Mr Poelmas Michiel with their donations. We hope to continue donating a minimum of sixty calculators per year.


Crypto Giants were running Saturday mathematics classes for grade 9 and 8 learners at Thulaganyo secondary school in Winterveldt, Pretoria North, in 2017. The total number of learners who participated in this programme is approximately 120. The school has more than 330 learners in grade 9 for mathematics. Most could not come due to transport challenges. The classes were divided into five groups of 25 learners each.  This programme started in March till September. It will resume again in Fenruary 2018. The main aim of these classes is to encourage learners to choose pure Mathematics in grade 10, not mathematical literacy.

Crypto Giants in partnership with SAASTA  hosted three math and science spring classes for grade 10 and 11 learners in Free State (Welkom), Nanabolela Secondary school, Free State(Botshabelo), Lefikeng Secondary school and in Gauteng Meyerton High school. The total number of learners who attended these camps was approximately 600. In these camps, the Crypto Giants also ran the Mathematics awareness campaign, which is aimed at recruiting learners to study mathematical sciences.

Crypto Giants did their annual team-building activity at Gold Reef City, in Johannesburg. Two Crypto Giants members, Mr Boitumelo Mahlobo and Mr Odirile Ntshudisani received funding for Honours studies from SARCHi chair, and Mr Ntshudisani, in addition, received funding to attend MASAMU programme and SAMSA conference in Tanzania, 16-26 November 2017.

Next year we plan to do more of the math and science camps and bring a few learners on campus for mathematics day.


Prof Jean Lubuma, Dean of the Faculty of Natural and Agricultural Sciences, participated in a Mathematics awareness initiative that targets high school learners. Grade 12 learners from the Reitumetse High School in Soshanguve learned more about the Under Twenty Mathematicians programme, Crypto Giant members, together with the founder of the Under Twenty Mathematicians (UTM) programme, 

Mathematics Awareness “Talent search”


High school learners are getting discouraged to continue with Mathematics because they think it’s hard and only for those that are considered super smart. Those that perform well in Mathematics do not consider it as a career. The other challenge is Mathematics performance for these learners when they get to their first year at tertiary institutions. They seem to struggle to bridge the gap between high school and university Mathematics. Many of the degrees require at least the first year of Mathematics. 

Goals to address this challenge

• Act as role models in Mathematics.

• Correct the perception about Mathematics.

• Develop Mathematics study skills.

• Provide information on careers in Mathematical Sciences

• Present the application of Mathematics in other fields.

• Provide mentors for learners who study Mathematics in high schools.

• Provide tutoring for high school Mathematics learners.

• Market Mathematics as a subject and career choice to high school learners.

• Recruit learners to study degrees in Mathematical Sciences at South African Universities, in particular, University of Pretoria.

• Motivate learners to do well in Mathematics and participate in National/International Mathematics Olympiads.

• Change learner’s attitude towards Mathematics.

Visits and Progress

In 2015 we launched a project to raise Mathematics awareness amongst high school learners in Gauteng and surrounding provinces. We targeted six schools but we only managed to reach four schools:

  • March 2015: Reitumetse Secondary School (Soshanguve) where we saw 100 Mathematics and Science learners from grade 12. Prof Jean Lubuma accompanied us. More detail
  • 8 May 2015: Tswaing Secondary School (Winterveldt) where we saw 110 Mathematics and Science learners from grade 11. Two members of the Crypto Giants are from these schools.
  • 15 August 2015: Nomsa High School (Vaal) where we saw 64 Mathematics learners from grades 11 and 12
  • 15 August 2015: Meyerton High School (Vaal) where we saw 80 Mathematics learners from grades 11 and 12
  • Mathematics and Science centre in Diepkloof, Soweto where we saw 150 Mathematics

Team Building trip

On 29 April 2015, we had a team-building trip to Gold Reef City in Soweto, with twenty of the Crypto Giants members, using two Mini-Bus taxis.

South African Mathematics Team Competition 15 September 2015

The 2015 Southern African Mathematics Team Competition (SAMTC) was held on 12 September. This is the yearly event where the top mathematical high school learners compete against each other on provincial level. Teams are decided on the ground of learner achievements in the second round of the SA Maths Olympiad, and the Siyangoba programme.

Two junior and two senior teams participated this year as the Gauteng North representatives. Gauteng North traditionally provides fierce competition to the other provinces. This year our Senior A and B teams came respectively 2nd and 12th from 47 teams and the Junior A and B teams 10th and 16th from 49 participating teams countrywide. Congratulations to these learners on an excellent performance!

The team manager was Ruaan Kellerman and the Siyangoba coaches were Harry Wiggins, Eben Maré and Hannes Haasbroek. To find out more about how SAMTC works, please go to http://www.up.ac.za/mathematics-and-applied-mathematics/article/47657/south-african-interprovincial-mathematics-olympiad.
