Math is old and new
Today we're going to consider two math websites.
1) Interested in learning mathematics with an abacus? While you can buy this age-old device about anywhere, at the website NurtureMinds.com you can find workbooks that teach arithmetic with abacus.
From the website:
2) Cut-the-Knot.org is a website hard to classify. The author says, "This site is for teachers, parents and students who seek engaging mathematics. "
Indeed, the Cut The Knot is full of engaging mathematical facts, lots of puzzles and thinking exercises, some proofs, games, paradoxes, mathematical facts illustrated with Java applets, mathematical droodles, and Miscellaneous! How about Eye Opener Series? And that is not all.
Anyway, most of Cut The Knot is enjoyable for those who have studied high school math, and maybe even beyond. It's definitely like candy for anyone who loves mathematics in all its aspects, full of little puzzles and interesting facts. Go visit the home page to find links to the interactive puzzles.
I want to feature one page from the site, for all of you who think mathematics stops at high school calculus, or for you who see 'black hole' when you think about all the mathematics beyond high school.
No, I'm not meaning for you to study it all, but just check this page: DID YOU KNOW?
It's good to be aware of the fact that mathematics is an advancing science, and that typical school mathematics covers mathematical knowledge only up to about early 17th century (that is, if you take calculus).
3) Well this third one isn't a website. Just a reminder; you can still participate in the giveaways drawing.

From the website:
"In Japan, educators maintain that the abacus helps children develop powers of mental calculation. It enables children to:
* understand the base-ten number system and place values,
* understand concepts of carrying and borrowing in arithmetic, and
* visualize close relations between numbers and numerals."
