SHS3 Design And Communication Technology · Semester 2, Week 2

Fractal Geometry

Lesson notes

Learning Objectives

Indicator: 3.2.3.LI.2 - Use the idea of fractal geometry to create complex fractal designs.

By the end of the lesson, learners can:

  1. Explain the two key properties of a fractal design: self-similarity at different scales and iterative repetition of a base shape.
  2. Select an appropriate geometric shape (triangle, square, or line segment) and a transformation rule to build a complex fractal design by hand.
  3. Construct a 2-level and 3-level fractal design accurately using drawing instruments such as a pair of compasses, set-squares, a protractor, and dividers.
  4. Produce a step-by-step pictorial report (manual drawing with annotations) documenting the process used to create their fractal design.
  5. Evaluate their own and peers’ fractal designs against set criteria for accuracy, complexity, and neatness of construction.

Exemplars (from the NaCCA curriculum)

Collaborative Learning/Managing talk for learning: Learners in groups brainstorm to select the types of geometric shapes they will want to use to create complex fractal designs and the relevant tools and materials that will be used.

Project-based Learning, Activity-based learning: Guide learners in groups/individuals to create complex fractal designs using the selected geometric shapes and relevant tools and materials

Project-based Learning, Activity-based learning: Let learners generate manual/digital pictorial reports individually on how they created the complex designs with the geometric shapes and the relevant materials and tools
- drawing instruments such as set-squares
- protractor
