- Have groups of 2-3 students work together to try calculate the 50th Fibonacci number using pencil and paper.
- Have another group (or groups) of students write code that will calculate the same Fibonacci number.
- Pick a number high Fibonacci number, like the 50th, so that the computer calculation takes a minute or two, giving the humans have a chance to do the calculation and beat the computer.
- An instantaneous answer that only takes the computer a few seconds to calculate doesn’t pose students with a challenge.
