To recognise and explain a number pattern.
Many of our ancestors have been investigating mathematical theories for millions of years?
It links to the world around us?
It is not something that someone has just ‘made up’?
0 1 1 2 3 5 8 1321
What are the next numbers in this sequence?
Can you work out the rule for this number sequence?
How can we record our findings?
34 55 89 144 233 377 610 987 1597
So what is the rule?
You add the last two numbers together to get the next number!
This number sequence is called Fibonacci numbers.
On many plants, the number of petals is a Fibonacci number and the seed distribution on sunflowers has a Fibonacci spiral effect.
Put a line under any number in the sequence. Add up all the numbers above the line.
What do you notice?
The total of all the line is one less than the second number below the line.
Is this true every time?
How can we record our results?
Take any three numbers in the sequence. Multiply the middle number by itself. Then multiply the first and the third numbers together.
Try this a few times.
Do the answers have something in common?
Are there any numbers that do not fit this rule?
Tip: Use a calculator to help you!
If you have time tonight Google Fibonacci and see where else his number sequence appears.
