“Matematinis miestas” (Math City) is an educational game for students in grades 9–10, developed by NIEKO and presented by Lithuania’s National Agency for Education’s EdTech Centre. Students solve problems based on everyday situations and discover where maths comes in handy beyond the classroom. In-game hints help them work out what each problem is asking and find a solution. The game celebrates correct answers and encourages students to try again when they make a mistake. Designed to complement classroom teaching, the game helps students reinforce what they’ve learned and prepare for Lithuania’s national mathematics assessment (PUPP).
