Wiixii

We are committed to helping the most underprivileged children in Latin America develop a healthy relationship with mathematics, learn basic problem-solving skills and obtain a growth mindset.

By delivering our content via WhatsApp we solve the access problem and succeed in exposing underserved populations to engaging math enrichment content that is both play-based and challenging.

We focus on improving students’ self-esteem and educating the participants and their parents about mindset and metacognition.  

Our math challenges and DIY math games promote habits of mind, critical thinking skills, resourcefulness, and the ability to solve open problems creatively.

Our ultimate goal is to challenge students’ view of themselves as life-long learners who are capable of problem-solving success in whatever domain they wish to pursue. 

If scaled globally, it will increase the number of underrepresented students motivated and supported to stay in school through and beyond high school.

The most underprivileged children in Latin America have very limited access to the Internet, instruction, or guidance. The Covid-19 epidemic has exacerbated this problem. The magnitude of the problems caused by the lack of proper education, guidance, and resources in children is impossible to underestimate.

Yet 95% of children in the region do have access to WhatsApp - through their parents' phones. By delivering our program via WhatsApp we can cost-effectively reach tens of millions of children, make them believe they ARE A MATH PERSON, and increase their interest in pursuing higher education, as well as their likelihood of future success, academically, professionally, and personally. There is extensive evidence linking education and motivation with future well-being. 

Each participant is assigned an individual code upon completion of an Airtable form. 

We add cohorts to WhatsApp groups and deliver engaging math enrichment content directly to their phones on a weekly cycle for 12 weeks. All the material goes out in the form of photos and short videos to minimize the consumption of the very limited data and connectivity our users have. 

For 4-7 year olds: guided math conversations to have throughout the child’s daily routine (mealtime, bedtime,…), and DIY math games to fabricate at home with recycled materials.

For 8-12 year olds: math puzzles along with complementary hands-on challenges to further the construction of knowledge.

The participants work on the puzzles, fabricate and play the math games and tackle the practical challenges on their own time. They submit their answers and evidence of their work directly to their Airtable portfolios via a linked form that we also share on Whatsapp.

Each individual portfolio is also a channel of communication. Parents can submit questions about implementation. Older participants can instantly check their corrected answers and receive formative feedback by trained volunteer moderators. We share the puzzle solutions in the form of short videos at the end of each week

Wiixii is the offshoot of We Puzzle Together, which has been delivering recreational math puzzles and organizing math festivals in communities in Ghana, Senegal, India, the US and several Latin American countries for the past 20 years. We have countless testimonials from parents and teachers about how even a short exposure to this content and approach to learning can impact the academic success of students.  “Our children are more motivated to learn. Our students have become leaders in their class, sharing math puzzles with their classmates. Our children are more focused on learning”. 

The pandemic was the catalyst for building a scalable model for the delivery of the content in a way that can reach communities isolated due to the lockdown and lack of Internet.

We make it extremely easy for poorly educated parents to implement a math enrichment curriculum at home without incurring extra expenses and without having prior math skills. All they need is a smartphone and the willingness to spend a few minutes with their children learning together. 

For our 8+ year-old users, the puzzles and challenges are an invitation to "do your best and become comfortable in the normal and unavoidable discomfort of learning something new".

We reach the children through schools, foundations, and companies that want to support the families of their workers.

We see evidence of acquisition of math competencies, improved self-esteem and habits of mind, and a huge impact on how parents perceive their children's capacity to learn. More than half of the families have reported improved math grades and a more positive mentality towards mistakes and math. 

We are certain this will change academic trajectories and translate into more children staying in school, pursuing higher education and succeeding in their chosen domains. 

Our focus on helping the most underprivileged children in Latin America develop mathematical thinking, creativity, and a growth mindset is perfectly aligned with the TPrize Challenge. Furthermore, our program works both as a stand-alone solution for children without any other educational resource, as well as a complement for teachers and educational settings that are focused on traditional programs.

We have found that, in addition to the tremendous direct impact that Wiixii has on the children, educators, administrators, and parents also learn how to better support and engage their children.

We are currently operating in 12 communities in Guatemala, Peru, Panama, Honduras, Venezuela and Colombia. Over 4,000 students have participated in our program and more participate every day.

The following are a representative sample of the specific communities in which Wiixii is operating:

A) Fe y Alegria: A non profit organization that works in the most vulnerable populations in Latin America. We are working through their schools in Guatemala and Peru.

B) Jupa: An extracurricular school for underprivileged youth in Panama. We are providing the content to the school and they are delivering it directly in the classroom.

C) Guarderías Infantiles: A non-profit organization of a MAQUILA in Honduras, we are working with the mothers providing the content so they can do it directly with their children.

D) CEMACO: a retail company in Guatemala. We are providing the content to the families of their employees.

Our use of WhatsApp for communicating with the children makes our platform significantly more scalable and accessible than solutions based on websites, apps, or other media. Additionally, our use of Airtable as a back end allows us to track all the children's interactions and perform sophisticated analysis on performance, engagement, and retention.

We've optimized our content both from a pedagogical standpoint as well as for effectiveness within the technologies that we are using. And we've developed everything to be scalable and accessible by the most underprivileged communities.

We rely on the integration of WhatsApp for communications and Airtable for data collection and programming logic. We leverage the fact that 95% of households in the region can interact with our technology through their smartphones.

The use of Airtable is very cost-effective and flexible, allowing us to constantly refine our processes and perform sophisticated analytics on the data, without the need for expensive tools or programmers. 

WhatsApp and Airtable also have APIs that we will leverage in the future to make our platform more scalable and responsive.

The activities are inspired by classical math games. We draw inspiration from some of the most progressive and creative math educators in the world including NRICH (Cambridge University), Youcubed (Stanford University), Math for Love, The Global Math Project, The Julia Robinson Maths Festivals, Alex Bellos, Nob Yoshigahara, Art of Problem Solving, and many others.

We rely on proven technologies already in use by hundreds of millions of people. Furthermore, our implementation has proven to work well with the thousands of students that have participated in our programs.

Here is a video of our program for the younger participants.

There are no technical risks to our implementation.

Our program currently serves over 4,000 participants. We expect to benefit 100,000 in the next year, to reach one million children in three years, and over ten million in five years. 

The above are those benefiting directly from the program. We are also currently working with teachers, providing them with the material so they can continue benefiting all their students after our program is over, and we are also working together with Universidad del Valle de Guatemala, training their future teachers (who become our moderators as part of their training) and they will continue impacting the life of all their students during their teaching careers. Therefore our impact will be much bigger, and reach more beneficiaries than the ones we have in our platform. 

During 2021 we grew over 10x to serve thousands of children. Our plans are to grown another 10x or more next year, and scale to help a hundred thousand children by the end of next year. Five years out we hope to reach over ten million children.

We reach children through schools, foundations, and companies that want to help their workers' children.

In order to achieve our goal we are partnering with different sectors, like the non profit sector through organizations like Fe y Alegria that have operations in more than 19 countries and have a network of more than 1,200 centers. We are also in conversations with the government of Chile to reach more than 2,500 families with our early childhood program (4 to 7 years old), big international organizations like World Vision with whom we are currently working on a program to reach 175,000 children in the highlands of Guatemala over the next 3 years, and private companies that will use our programs as part of their Corporate Social Responsibility strategy. 

Goal 1- Reach and engagement: Daily surveys generate massive amounts of data that allows us to track number of users and level of engagement, perception of learning as well as performance in solving the puzzles and challenges over time. The flexibility to change the daily surveys and to target subgroups in the program affords a unique opportunity to evaluate the effectiveness and impact of the program. Thus we can easily track the consistency of each user’s participation and address unproductive struggle. Additionally, we can analyze engagement with each puzzle and challenge in order to fix problematic content (clarity, fun factor, need for more scaffolding). This will allow us to continually iterate and improve.

Goal 2 - Impact: We plan to do many large randomized trials in diverse communities to measure the effectiveness of our programs. We are currently running a trial with 850 students from 5th and 6th grade from Fe y Alegría schools in Perú. We will use pre/post student surveys developed by Stanford University Youcubed to measure: beliefs about Math (conceptual, connected to the world), beliefs about error and speed (reducing math anxiety), and beliefs about who can learn (mindset, effort, persistence, struggle). We will also measure changes in mathematical learning with program metrics, school data, and analysis of student work samples.

Additionally, the Airtable platform allows us to share anonymized data with external researchers. We are very open and excited to contribute to the understanding of the science of learning.

We are excited by the resources that the TPrize would provide. In particular, we would greatly benefit from interacting with relevant experts and organizations in Latin America and in the world of education in general.

Introductions to mobile operators in the region would be most helpful, to help us address the challenge of the cost of data. We would also benefit from experts that can help us optimize our content and our technology.

As we scale, we want to collaborate with educational institutions in the region that can help us scale our network of moderators.

Finally, we hope that the TPrize network can help us reach companies, schools, and foundations interested in offering our programs to their children.

We would benefit from partners who help us grow our team, both of full-time employees, contractors and advisors.

We could benefit from local experts in each of our target countries and communities.

Introductions to companies, schools, and foundations would accelerate our growth.

We are always looking to optimize our technology implementation.
