Discover how a simple adding rule grows into stunning spirals and appears in flowers, shells, and more. In just half an hour you’ll build the sequence, sketch the Golden Spiral, approximate the Golden Ratio, and spot these patterns all around you.
5 modules • Each builds on the previous one
Introduce the Fibonacci sequence, emphasizing how each term equals the sum of the two preceding terms, starting from 0 and 1.
Show how ratios of successive Fibonacci numbers approach φ (approximately 1.618) and relate this to spiral growth.
Convert the numeric sequence into a series of adjacent squares whose side lengths follow Fibonacci numbers.
Guide learners to connect quarter-circle arcs across Fibonacci squares, revealing the Golden Spiral.
Explore real-world examples—sunflowers, pinecones, nautilus shells—where Fibonacci spirals appear, emphasizing pattern recognition.
