Every year on 17 June, World Tessellation Day is celebrated. This day is dedicated to the art of creating mosaics that consist of geometric shapes that fit together perfectly without gaps or overlaps.
Tessellation, or parquetry, is a mosaic of several identical shapes that fit together without gaps or overlaps.
The aim of World Tessellation Day is to raise awareness of the mathematical principles of tessellation and encourage people to explore this fascinating field. On this day, students create their own tessellations and judge the work of their friends.
