The event followed a similar format that teachers and students have become used to over the years, though this year the second Math Day coincided with the latest SIS world-wide collaborative project – an online Mathletics competition. Students of SIS Friedrichshafen lined up in teams within their classes and competed against SIS students in the same classes from schools in Germany, Switzerland and Brazil. The afternoon at SIS Friedrichshafen saw all Grade 1 to Grade 10 students compete individually and in teams against their peers in other schools with varied success. Classroom atmospheres varied from iron concentration, raucous comradery and at times unfathomable confusion. While we did not take home any winner’s prizes, our students’ engagement with math processes and problem solving was the real winner.
