Buffon's Needle

This Buffon's Needle interactive also includes:

Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based on the experimental probability of the needle's placement.
