  1. Where’s the Math?? Presentation by Melissa Hogg, Curr 383 E

  2. What Is a Tessellation? • A shape or tile that repeats to fill a surface without any gaps or overlaps. • The name comes from the word tessella, the small square tile used in ancient Roman mosaics.

  3. Tessellations Around Us • We are exposed to tessellations everywhere. • Do you recognize these common tessellations? • How many tessellations have you seen today?

  4. Math in Tessellations • Many different geometric shapes can be used to create tessellations. • Which of the shapes below would fit with itself to make a good tessellation design?

  5. Patterns • Very basic tessellations are simply a repeating pattern. • The rule is that you have to make sure that the shapes fit together leaving no open space on the page.

  6. Symmetry • Symmetry is an important part of tessellations. • Geometric shapes can be translated, reflected, rotated, or glide reflected. • These movements of the shapes creates a more interesting tessellation design. Translation Reflection Rotation Glide Reflection

  7. Professional Tessellation Designs Sun and Moon M.C. Escher Fish Robert Ingalls • Many artists have created master works of art using the simple rules of tessellations. • M.C. Escher and Robert Ingalls are among many tessellation artists. • Can you you spot the repeating shape?

  8. You Can Be a Tessellation Artist You need to first create a tessellating template. • Step 1: using grid paper cut out a perfect square. • Step 2: with a pencil make a line on two adjacent sides of the square. Be sure not to draw through a corner. • Step 3: cut out the pieces and attach them with tape to the opposite sides from where they came.  You have now created your tessellation template.

  9. Seeing a Figure • Looking at your tessellation template, study the sides and the shape to decide what sort of figure you might see. • The person who designed this form saw an elephant and an elf. • Are there any other different forms that you might see? • When looking for the shape be sure not to see too much detail as it can make the art work too crowded.

  10. Putting It All Together • Take your tessellation template and trace it on to a piece of paper. • When tracing you can use different types of symmetry to change your picture. • Be sure that your whole page is filled with a repeating pattern. • Colour in your picture creatively.
