In the early days of summer nature has a way of entertaining us with magical views of flowers in full bloom. A kind of neat phenomena that makes everyone who is not too busy take notice. A camera can capture such a scene in its full glory. Mathematical photos such as graphs can also reveal some interesting neat phenomena that can bring about similar rewards. At least it did for me when Kelvin Misco of Wolfram Research at their booth at the NCTM conference in April showed me what happens when you type the name Chelsea at the Wolfram Alpha website. You can do additional baby name investigations at this cool website. Type a name and see what happens. Students really like this one and will explore it in interesting ways without much help. I'm curious if any math teachers have used this. If you try it with kids let me know how it went.

Wrap your brain around this one. Makes perfect sense. Doesn't it? I just checked on my calculator and the total is right. Even in Gold Hill over a 150 years ago they would have gotten an "A" for addition. But making sense out of things wasn't one of their strong points.
This sign - well actually one similar to this - gave me an idea for what I (or you) can do with this.
