A few weeks ago my younger son was looking for something to print and we stumbled on this dice tower on Thingiverse:
wtwerner’s Spiral Dice tower on Thingiverse
Today I used the tower for a fun little statistics project with the boys – does the tower produce random rolls?
The first part of the project was a discussion of how we should conduct the experiment.
After this discussion I sent them off roll the dice 60 times:
Here’s the discussion of their results and some ideas for further experiments:
It would be nice to do a project like this with more kids so that you could compare lots of results, but even with just the two boys this morning, it was pretty fun. I really enjoyed hearing them talk about the numbers. They were especially excited by the fact that no 2’s showed up until the 26th roll.
