Select ratio of turn angle. Click flag. Clones turn that angle. Select 34 in numerator and 55 in denominator (both Fibonacci numbers) you get 34 space filling golden angle spirals and 21 clockwise spirals. Or select 55 in numerator and 89 in denominator (sequential Fibonacci numbers). Their ratio is the golden ratio.
This is one model used for our class on ratios and spirals. Shared so the students can follow along.
