MathematICS FESTIVALS
To show the students there is more to Mathematics than what they see in the classroom, and share my love of recreational mathematics, I have taken part in organizing multiple Mathematics Festivals in University of Southern California and later in Galatasaray University (see tutamtutammatfest.com).
Here are some photos of me hosting the combinatorics table. More details on the puzzles I use are here.
So many things to play with!
