Okay here is my contribution, I had to post it on a SuperSwiki as I am still having problems posting to the Showcase :(
You can find the project here: http://swiki.ofset.org:8000/seaside/SBSuperSwiki/bfeb1910-c26e-4409-a2c4-5680842016a9?_s=TSJMVzFGZOHAQkcV&_k=gGeheatu

Page 3 keeps Randy's project pi (so it can be incorporated). I like Randy's approach as a first step for kids. Using this, especially in a class where they will all get slightly different perimeters for a four sided polygon, is a good way to start.

Still to do (previous entry clipped):
1) add label showing length of triangle segment to facilitate calculating perimeter
2) add label showing area
3) add Richo's graph tool to let the kids plot ratio of perimeter to diameter vs # of side, so they can see it converge

In the spirit of the group challenge I do not mind if anyone would like to take on any of the above items, help is always appreciated ;)

Randy,

This is a translation to Spanish of the English tab in your Pi project:

============

Guía

Observa como los perímetros de los polígonos inscritos y circunscritos al círculo, se aproximan a pi al aumentar el número de lados. Los valores de los perímetros son tales que el diámetro del círculo resulta igual a 1. El valor de los perímetros se acerca así a pi.

Para agregar un lado al polígono, haz clic en un triángulo verde. Luego arrastra los vértices para inscribir y circunscribir los nuevos polígonos. Finalmente, haz clic en el botón "CheckPi" para ver los nuevos resultados.

===========

If you could add a second tab in Spanish, it would be appreciated by many Etoys enthusiasts.

If the accents give you any trouble, you may replace the same letters without accents for the accented ones.

It will not look perfect but it will be readable without any problems.

Thanks.

When you read my comments to your project, my English might sound a bit more weird than usual.

The reason is I wrote the comments in Spanish, if you select English in the Squeakland website, you will be looking at the automatic translation.

Carlos
