BIG NUMBERS and a COOL SITE

Thanks to Tom Avent for sharing two Youtube channels I had not seen before, and I like to watch science and maths videos. I spent about an hour looking around.

Here is one to get you started with some big numbers from the good people at ASAP Science:

But wait... there's more...
This is another excellent Youtube channel called FW Thinking

Enjoy! I did (:

Roman Numerals

Hello all - Catherine Fee shared this video with me and we watched it in class to look at a way of communicating your knowledge and understanding of a number system from history.

Thanks Catherine!

Mathematical Humour

Thanks to Jack Edwards, in 7D,  for sharing this Mathematical joke. Have you seen any funny mathematical jokes?


Thanks to Stephen Guerra, in 7D, 

History of Number Systems Investigation - some links

Where to begin when looking for information on different number systems?

You could ask your parents - maybe they know about a cool system for numbers and counting. 

You could ask your librarian - there are books about mathematics!

There are some sites online too. Ms. O'Hara and I have found some sites to share with you.
If you search, use good search terms. One of my favourites is "for kids". I use this in almost every search I do (:

Binary at mathisfun http://www.mathsisfun.com/binary-number-system.html
Counting on your fingers with binary http://www.mathsisfun.com/numbers/binary-count-fingers.html

Roman Numerals http://www.ducksters.com/kidsmath/roman_numerals.php

Archimedes Lab http://www.archimedes-lab.org/numeral.html

Numberphile is a wonderful Youtube channel

This one has a long list of number systems and labels their complexity or simplicity with happy and not so happy faces.   http://gwydir.demon.co.uk/jo/numbers/comparison.htm  
Another page on this site is http://gwydir.demon.co.uk/jo/numbers/index.htm with a few famous number systems.

This is a bit more ‘wordy’: http://www.math.wichita.edu/history/topics/num-sys.html

This site had some interesting facts, but it might be a little challenging with its sophisticated matheamatical language http://mentalfloss.com/article/31879/12-mind-blowing-number-systems-other-languages
