Circumference and the First Round Table: A Math Adventure. (Part II, more plants and sequencing and WHY plants have this sequence). (this one moves fast, but really relates it to the plants I’ve been using as examples….worth sticking it out to the end). How do I count the spirals? Museum of Mathematics Website article If you are looking for a way for students to understand the importance of number sequences and patterning in the real world. See what you think! Be ready for a great discussion!Įverything you wanted to know about Fibonacci Is it just a coincidence? Or is there a purpose behind the patterning? Visit some of the links and watch some of the videos. In the coming weeks, I’ll be interested to know what the students think the reason is (or why) this pattern of numbers exists on plants and in nature. Well, yes, it is….but the perimeter of a circle has a special name! Circumference! Finally, I outlined the head of the sunflower with my finger and asked them to name this measurement! The answer that was most often offered as it is the perimeter. And that is “why” I am spending the time to introduce this number concept to the garden club students!Īs I showed the students the huge sunflower heads from our garden, I asked them to think about the relationship between the height of these plants (I asked for guesses here) and the size of the heads (most were about 12 -17 inches in diameter). Wondering “why” is exactly our garden club theme this year. Of course, that is because I always want to know the reason “why”. Wondrous, in fact! I have long been attracted to the beauty I find in my garden, but knowing there might be some rhyme and reason behind that beauty makes it all the more attractive to me. Using this formula we can easily calculate the nth term of the Fibonacci sequence as, for. Where is called the Golden Ratio and its value is, 1.618034. There are also some great websites and videos that apply this concept in a visual sense. The important properties of the Fibonacci Sequence are, We can easily calculate the Fibonacci Numbers using the Binet Formula, Fn (n (1-)n)/5. It appears in many more places than those mentioned above. So, I’d like to leave the students with the challenge of looking for the Fibonacci sequence in nature. They are right in front of you! A sixth grader I know says, “Everything is math and math is everything!” Right now, I can’t find an argument for this! This student remembered the sequencing from an advanced biology class, not a math class! Do you see the overlap here? Mathematics is an integral part of science and science is an integral part of math! You just need to be curious enough to look for the connections. Heres an interesting example called the Fibonacci series, named after an Italian mathematician of the Midde Ages, though the Greeks clearly knew all about it much earlier, as evidenced in the design of classical architecture such as the Parthenon. It was interesting to note that none of the students in the garden club this year had heard of the Fibonacci Sequence before! The high school volunteers had heard of it but only one knew how the sequence was generated or what it applied to. Math is at the heart of many of the patterns we see in nature. Thirdly, is that it makes the subject of math more beautiful! And lastly, for our group, it provides some enrichment for those students who are looking to stretch their knowledge base. That has saved us all a lot of trouble! Thank you Leonardo.įibonacci Day is November 23rd, as it has the digits "1, 1, 2, 3" which is part of the sequence.So, why am I bothering to show the students this? For one reason, it is just cool to be able to recognize how this pattern repeats itself over and over on living things! The second reason is that it makes the students think about math and patterns found in everyday life. "Fibonacci" was his nickname, which roughly means "Son of Bonacci".Īs well as being famous for the Fibonacci Sequence, he helped spread Hindu-Arabic Numerals (like our present numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) through Europe in place of Roman Numerals (I, II, III, IV, V, etc). It is also called nature’s secret code and nature’s universal rule. The Fibonacci sequence is one of the most famous formulas in mathematics. His real name was Leonardo Pisano Bogollo, and he lived between 11 in Italy. For my Class 11 Applied Mathematics Project, I took up the topic FIBONACCI SEQUENCE : Its History and Presence in Nature from the list of topics provided by CBSE. Historyįibonacci was not the first to know about the sequence, it was known in India hundreds of years before! Which says that term "−n" is equal to (−1) n+1 times term "n", and the value (−1) n+1 neatly makes the correct +1, −1, +1, −1. In fact the sequence below zero has the same numbers as the sequence above zero, except they follow a +-+. (Prove to yourself that each number is found by adding up the two numbers before it!)
