📖 Read the story
Nature has a secret math pattern. It is the Fibonacci sequence. A sequence is a list of numbers in order. To make it, you add the last two numbers together. For example, 1 + 2 = 3, and 2 + 3 = 5. Flowers love these numbers. Many flowers have 3, 5, or 8 petals. You can also see this in pine cones and sunflowers. Their seeds grow in a shape called a spiral. A spiral is a curve that goes around a center point. Why does nature use math? It helps plants grow well. The pattern helps petals and leaves fit together easily. This way, they do not waste space. Every leaf can get a lot of sunlight. This helps the plant stay strong and healthy. Next time you go for a walk, look at a flower. Count the petals. Can you find a secret number?
