Fibonacci Numbers: A Fascinating Sequence
1, 1, 2, 3, 5, 8, 13... each number is the sum of the two before it. This simple pattern shows up in nature everywhere.
The sequence rule
Start with 1 and 1. Each next number is the sum of the two before it: 1+1=2, 1+2=3, 2+3=5, 3+5=8...
💡 Practice: ask the child to continue the sequence on their own after 13 — great practice for attention and addition.
Fibonacci in nature
The petal count of many flowers follows Fibonacci numbers: 3, 5, 8, 13. A snail shell's spiral follows the same pattern too.
