Tessellations are shapes that fit closely together without leaving empty spaces or overlapping. St. Mary School’s middle school students learned how the artist, M. C. Escher, creatively designed many tessellation illusions using complex geometry. In Math class this week, they created a Collaborative Tessellated Christmas Tree for which each student created their own personalized piece. When those pieces were brought together, a beautiful new pattern emerged. St. Mary’s grade 6-8 Math teacher, Mrs. Horan, explained that the Tessellated Christmas Tree symbolizes how our differences as humans, when brought together in unity, creates an harmonious and beautiful community.
