Proportions and scale: textiles
Lesson details
Learning outcome
I can determine and justify the size of my design.
Key learning points
- Design decisions are justified.
- Measurements, scale and proportion are design decisions which must be justified.
- Designers can work to scale which is calculated.
Keywords
Specification - describes what a design must have or do
Justification - the reason or explanation for why something is done, or believed to be right
Proportion - balanced relationship between different parts
Dimensions - the sizes of objects or components
Scale - a ratio of full size
Common misconception
All prototypes must be life size.
It is not always possible to manufacture life size prototypes. The space to manufacture and store may be limited plus the materials may be expensive. A smaller scale product saves space and materials but still allows for a product to be manufactured.
Teacher tip
This lesson is the perfect opportunity for students to learn about standardised scales but also to work out the sizes of their own design.
Equipment
Rulers, scale rulers if available but not essential, paper, pencils
