Are any activities only in the morning?

Yes. Two games from APDIO, the SOS decision mission and Equilíbrio em Jogo (a money and wellbeing game), run 10am to 1pm only. The other stalls run until closing.

Is there anything for teenagers?

Yes. The FCUL math department's puzzle stall is aimed at basic and secondary school students and also covers its degree courses.

Can we buy math games there?

Yes. Associação Ludus, the math teachers' association (APM) and the Portuguese math and statistics societies have stalls selling teaching materials.

Who is the Martin Gardner talk for?

It's billed for families and the general public. Jorge Nuno Silva of Associação Ludus gives it in Portuguese, on the writer whose decades of Scientific American articles made math popular.

About

The Feira da Matemática is a yearly math fair at Lisbon's natural history and science museum. Teachers, universities and math clubs set up stalls around the building, and kids move from table to table playing board and card games, cracking puzzles and taking on math challenges. It suits curious school-age kids who like puzzles and games. Activities are led in Portuguese.
