This work proposes an interactive game using Arduino in a maths olympiad for primary school students. The inspiration for this approach arises from the need to facilitate the teaching and learning process in maths classes using an attractive and playful methodology through a game for students. The idea is to apply a maths Olympiad in the form of a quiz and propose building the equipment with the help of the students in a bid to involve them in the dynamics of the game. The quiz consists of a game of questions and answers, which will be played by three teams of 8th grade students from a state public school Loide de Miranda Bossois is a teacher in the Goiás state public school system. She specialises in Educational Robotics for the Teaching of Mathematics and its Technologies at the Federal University of Catalão (2024), specialises in Technologies Applied to the Teaching of Biology at the Federal University of Goiás and has a degree in Biology from the Catholic University. Each team will be made up of five members, one of whom will be the captain. The aim of the game is to get the highest score.
