This project is very interesting and I believe that it can be a motivation for brazilian students. I think that more contributions can be added if more people could understand the texts. So I propose to translate content to brazilian portuguese as it be published and suggest changes according brazilian speakers use it.

I'd be great if you can add some more information, a logo (maybe @mikkokotila you can add an avatar to your profile?) You can also edit your goals in opencollective.com/jupyter4kids/edit
Let me know if I can help in any way, I'd love for your mission to succeed!

Hi,

In this notebook: https://github.com/mikkokotila/jupyter4kids/blob/master/notebooks/numerical-computing-is-fun-2.ipynb you use the 'is' keyword to compare numbers.

This should be avoided, because Python's semantic does not guarantee that '1 is 1'. In fact, in the CPython implementation, this is only True for integers lower or equal to 256:

>>> a = 257
>>> b = 257
>>> a is b
False
>>> a = 256
>>> b = 256
>>> a is b
True
