Lisbon Math: A Guide for Teachers and Educators
Turn everyday Lisbon scenes into engaging math lessons. This guide shows how to use the Lisbon Math flashcards for structured classroom activities, group work, and real-world problem solving across three skill levels.
Why use Lisbon Math in your math lessons?
Every card is grounded in a real scene from Lisbon — a tram ride, a pastelaria, a tiled wall — so students see mathematics in action rather than in abstraction. The problems are designed as real world math problems: calculating change, estimating distances, comparing prices, and spotting patterns in the city around them.
The back of each card includes an insight that connects the calculation to adult life: verifying a receipt, budgeting a trip, or reading a utility bill. This bridges the gap between the classroom and the street.
Adapting the three levels for group work
Explorer — Ages 10–12
FoundationExplorer cards cover multiplication, division, fractions, area, and basic rates. Use them to build number confidence with familiar objects: pastries, tram tickets, and tiled walls.
Market Stall Simulation: Print four Explorer cards and assign each group a Lisbon "stall" (pastéis, sardines, tram tickets, fruit). Groups price items, handle imaginary customer orders, and verify change together. Rotate stalls every 10 minutes so every student practices multiplication and division in a new context.
Navigator — Ages 13–15
IntermediateNavigator cards introduce percentages, ratios, speed, currency exchange, and probability. These are the math lessons that students will meet in personal finance, travel, and science.
Budget Your Lisbon Day: Give each group a Navigator deck and a fictional €50 daily budget. Students must choose activities from the cards, calculate discounts, convert currencies, and present their itinerary. The group with the most experiences and the least leftover wins — but every calculation must be defended to the class.
Architect — Ages 16–18
AdvancedArchitect cards tackle compound interest, optimisation, geometric proofs, statistical inference, and modelling. These real world math problems prepare students for exams and for adult decision-making.
Design a Miradouro: Each group receives an Architect card about area, angles, or structural load, plus a fictional hillside plot. They must design a viewing platform that maximises visitor capacity while staying within budget and safety constraints. Groups present their models, critique each other's assumptions, and vote on the most elegant solution.
Tips for mixed-ability classrooms
- Pairing strategy: Match an Explorer-level student with a Navigator partner. The stronger student articulates their reasoning; the other checks the arithmetic. Both learn from the exchange.
- Jigsaw method: Divide a complex Architect problem into steps. Each group masters one step, then groups reform so every new team has one "expert" per step.
- City swap: Ask students to rewrite a Lisbon scenario for their own town. This reinforces the underlying mathematics while building ownership of the material.
- Exit tickets: End each session with one card solved independently. Review the insights the next day to cement the connection between calculation and real-world meaning.
