Tessellating Art


In this unit we apply our understanding of why tessellations work to form our own unique tessellating shapes. We use these shapes to create interesting pieces of art in the style of M.C. Escher.

Achievement Objectives
GM4-8: Use the invariant properties of figures and objects under transformations (reflection, rotation, translation, or enlargement).
Specific Learning Outcomes
  • alter polygons to create unique shapes that tessellate
  • describe the reflection or rotational symmetry of a shape or tessellation
Description of Mathematics

This unit is built around the famous artist Maurits Cornelius Escher. Escher was born in Leeuwarden, Netherlands on June 17th, 1898. He studied at the School of Architecture and Decorative Arts in Haarlem but soon gave up architecture in favour of graphic arts at the age of 21.

Escher is famous for two types of engravings. One of these involves impossible situations and the other is his variation on the theme of tessellations. A typical impossible situation shows four men climbing stairs. As you follow the men around and up their particular flights, you realise that they are going round and round. With regard to tessellations, Escher took a tessellation and, by adding and subtracting from the basic unit of the tessellation, turned it into a repeated picture.

There are many web-sites that explore the life and work of M.C. Escher. You can easily find one by entering his name in your search engine.

By emulating Escher and exploring tessellations in this unit, the students will gain a greater appreciation of the way that tessellations work. Hence they will see how mathematics, art and even nature, interact.

Other units that refer to tessellating are Keeping in Shape, Level 3 and Fitness, Level 4. It might be useful to have done Measuring Angles, Level 3 before tackling this unit.

Required Resource Materials

altered square tessellation

bumpy square tessellation

cardboard squares, parallelograms, "wonky" quadrilaterals, triangles, hexagons.


Getting Started

We begin our exploration of tessellating art by altering squares and parallelograms.

  1. Show the students the copymaster of the altered square tessellation.

What can you tell me about this tessellation?
Why is it a tessellation?
Which of the regular tessellations does it remind you about?
Can you see how this tessellation has been made? Show us.

  1. Look at the tessellating shape and predict how it was altered.


  2. Give each student a square cardboard tile. Ask them to cut a piece out of one side of the square. Attach the cut out piece to the opposite side of the square with cellotape.
    Will your new shape tessellate? Try it and see.
  3. Have the students trace their new shapes several times onto blank sheets of paper to see if the altered shape tessellates.
  4. Discuss.
    Is your altered shape symmetric? What type of symmetry does it have?
    Does the new shape have to be symmetric to tessellate?

    (Note: When altering a square by translating opposite sides to form a new tessellating figure, the alteration does not have to be symmetrical.)
  5. Have the students repeat the altering process with other quadrilaterals that tessellate, for example, parallelograms and rectangles. Also include "wonky" quadrilaterals. Not all alterations will create tessellating shapes and this a useful discovery. The key to creating tessellating shapes is altering opposite sides in exactly the same way.
  6. Allow time to share and discuss at the end of the session.
    What did you discover about altering shapes to create new shapes that also tessellate?
    Why do you think it is possible to alter shapes in this way and still end up with a shape that tessellates?
    Did you create any shapes that do not tessellate? Why do you think that they won’t tessellate?


Over the next 2-3 sessions we use our imaginations to create interesting art pieces using altered tessellating shapes.

  1. Begin by looking at one of the shapes created yesterday.
  2. Brainstorm for ideas about what the shape could be. In the following shape the addition of an "eye" creates a fish-like shape.

  3. Have the students select a shape to use for the basis of a piece of tessellating art.
  4. After they have decided on a shape, have them trace it across a piece of paper to create a tessellation. To transform it into an Escher style piece let them put details on each of the shapes.
  5. Ask questions as the students work that focus on the symmetries of the shape and the tessellation.
    Tell me about the symmetries of your shape? (reflection symmetry, rotational symmetry)
    How are you generating the tessellation? (translating? rotating? reflecting?)
    Why does your shape tessellate? (Encourage the students to focus on the sum of the angles at any point must equal 360 degrees)
  6. Ask the students to make a written record about the process that they used to make the tessellating shape and the tessellation.
  7. At the end of each session share the tessellating art.


In this final session we analyse tessellations and attempt to predict the processes that were used to create them.

  1. Begin by looking at the copymaster of the bumpy squares tessellation
    What shape do you think has been altered?
    How do you think it was altered?
  2. Next we distribute our tessellating art, created in the previous days, to see if others can determine the tessellating shape and the process by which the tessellation was formed.
  3. We check with the artists to see if we predicted correctly.
