What mathematical concept is reflected in the students' activity of creating tessellations?

The activity of creating tessellations reflects the concept of infinity. When students engage in this type of geometric art, they often explore patterns that can theoretically extend indefinitely in all directions. Tessellations are formed by repeated geometrical shapes that cover a plane without any gaps or overlaps. This can lead to discussions about how these patterns might continue indefinitely, essentially representing an infinite process.

In creating tessellations, students not only practice their spatial reasoning and geometric skills but also come to understand the idea of repetition and infinite patterns in mathematics. This connection to infinity emphasizes how mathematical concepts can be visually represented and can transcend finite boundaries, as the patterns can be drawn and continued without end.
