Wil and I attended OTC Houston yesterday with our eyes open for math. We looked at everything in the style of #AnyQs, the Any Questions? Game popularized by Dan Meyer and Colin T. Graham.

The idea is to see, hear or otherwise observe something and ask the first questions that come to mind. Ideally, one of the questions you might ask could lead to using and discovering mathematics to answer it.

For this set of images from OTC Houston, you can play two ways:

- Open this text file to write your questions and then copy and paste it into the comments.
- Tweet out individual questions using the handy links under each image.

I’ve included one or two of my own questions about each image too. What information would you or your students need to answer them?

### #1 – Rig Power

What’s the diameter on the inside and outside of the circles? How thick is the material? What’s the circumference?
