A short read for Class 8 before you play. These notes cover Exploring Some Geometric Themes: fractals and visualising solids.
🌿 Patterns inside patterns
A fern leaf has small leaves that look like the whole leaf. Shapes like this are fractals. The Sierpinski carpet removes the middle of a square split into nine, and repeats the idea on every square that is left.
❄ Growing shapes
The Sierpinski triangle keeps 3 triangles at step 1, then 9, then 27, multiplying by 3 each time. The Koch snowflake adds a bump to every side, so its number of sides multiplies by 4 each step.
📦 Seeing solids
Solids have faces, edges and vertices. A prism with an n-sided base has n + 2 faces, 3n edges and 2n vertices. A net is a flat pattern that folds into a solid, and a cube has 11 different nets.
