• 1. What is a pattern? Teachnet 2005 Nicola Gardiner © 2005
• 2. What is a pattern?
• A pattern relies upon three characteristics:
• A single motif
• Repetition of the motif
• A system of organisation
Nicola Gardiner © 2005
• 3. Four main pattern techniques
• There are four basic ways that you can repeat a motif to create a pattern
• Repeats, half drop repeats, reflection and rotation
• Mathematicians call these repetitions “rigid motions” because the movements do not lead to any change of size or shape of the original motif.

• 4. Repeats
• This i s rigid motion where the motif is simply repeated over and over along horizontal and vertical lines

• 5. Half drop repeats
• This is a rigid motion where every other line of motifs is staggered.

• 6. Reflection
• Reflection is rigid motion where the original motif is reflected across a line or axis.
• This creates a symmetrical pattern

• 7. Rotation
• Rotation is rigid motion where the original design is rotated around a single point
Nicola Gardiner © 2005
• 8. Rotation through different angles Nicola Gardiner © 2005 120 degree rotation 180 degree rotation 60 degree rotation 90 degree rotation
• 9. Reflections and rotations Nicola Gardiner © 2005
• 10. Other combinations Nicola Gardiner © 2005
• 11. How many patterns can you make starting with a simple motif? Nicola Gardiner © 2005
