## Math Monday: Tree Math.

Firstly…hello my fellow bloggy friends! I’ve missed you! Did you know there are places in the world without free wifi? Yes it’s true. So don’t go to Fresno if that thought freaks you out.

I spent a great 4 days up at Yosemite, Sequoia, and Kings Canyon National Parks. It was a hectic, but fun, time! Which describes so much of my life, actually.

In any case, even on vacation we used a spectacular amount of math. It can be done! And luckily, Sonja had just done her fantastic circle math (posts here but especially this one here having to do with circles and pi.)

In Sequoia, we were surrounded by giant trees.

This one is the 3rd largest in the world!

As we walked around, the signage between each tree gave out the diameter of the tree, but we wanted to know the circumference. The application being c=D*pi. Sometimes a circumference was given without the diameter. In that case, D=c/pi. These concepts came easily to the kids because of our labyrinth math experience, and also because it was relevant with a very practical application. They spent the day approximately calculating circumference and diameter (approximate because we used “3-ish” to stand in for pi đ ). We also hugged a lot of trees.

and occasionally sat in them too.

Remember in high school math when you (or maybe not you, but I certainly did) asked, “When will I ever use this in real life?!” I still don’t know why that’s a bad question. I’d say a good 3 years of math knowlege was totally wasted on me because 1) I don’t use it in real life or 2) I wasn’t taught how to apply it in real life.

There’s a reason the ancient greek mathmaticians were also powerful philosophers…they connected the world to a language of numbers. How sad that we have systematically disconnected the language of numbers from the world in our current system. So, let’s put them back together! It’s much more fulfilling that way.

Now go! Find math outside!

1. What a great post and a great trip! We’ve been finding fibonacci numbers outside.

• Oh, fibonacci numbers! those are fun for outside! If you blog it, I’ll link it!
