What is Brainfinity?

Brainfinity is a collaborative problem solving challenge, a unique competition in the region in which elementary school students in years 5 through 8 and high school students solve real-life problems in teams using all the benefits of Information Technology.

This allows students to experience project-based learning (PBL), which enables them to explore topics they are interested in through an entirely different approach.

PBL principles were used in Matematika 5, a textbook created by professors Ivan Anić and Radoje Košanin. A problem solving competition such as this one helps students strengthen their cognitive abilities, learn about teamwork, explore their curiosity and enhance their critical thinking skills.

How to create a team in 5 steps?

Ime ekipe

1. Think of a team name

Create a four-member team and think of an original team name. If you register a team name that already exists, you will be assigned a number, as well. So, be as original as possible!


2. Find a mentor

One of the rules is to find a teacher who will guide through the competition. Discuss it with your teammates and vote, and check whether the teacher is willing to embark on this adventure with you.


3. Create a team logo

Think of what best describes your team, what your favorite colors are and try to incorporate all these elements into a team logo. Use an online editor to create a distinctive visual identity for your team and let your imagination run wild.


4. Make a team photo

A group photo will represent your team throughout the competition. Here we expect you to employ innovation and creativity. Ask your parents or friends to help you make the best shot. And don’t forget – the mentor is also a part of the team.


5. Create a team email

We suggest you name your email after your team name. This will allow you to not only remember your email easily, but to strengthen your team image as well. Surely you know that almost every company in the world has an official email address?

Register and may your detective work begin

The competition is open to all elementary school students in years 5 through 8 and high school students who are interested in logical problem solving and brain games. A team competes in the class of the oldest team member.
