Published in 2011, "reveals the secrets of amazing, fun-to-perform card tricks--and the profound mathematical ideas behind them--that will astound even the most accomplished magician. ... Each card trick introduces a new mathematical idea, and varying the tricks in turn takes readers to the very threshold of today's mathematical knowledge. For example, the Gilbreath Principle--a fantastic effect where the cards remain in control despite being shuffled--is found to share an intimate connection with the Mandelbrot set. Other card tricks link to the mathematical secrets of combinatorics, graph theory, number theory, topology, the Riemann hypothesis, and even Fermat's last theorem."

SUPERB! Place the numbers on the number line. Loads of levels. Negative numbers and decimals. Play against the clock for a score. My class's favourite warm up, useful throughout school from year 3 to year 6.

Math Apprentice answers the question that is on the minds of most math students: When are we ever going to use math in the real world? This rich, multimedia site provides students an opportunity to try various professions that use math. Students can be scientists, engineers, computer animators, video game programmers, and more. Math Apprentice provides areas of free exploration as well as specific problems to solve.

I wish we could add tags to other people's items without overwriting their authorship!

Steven, you shared a link and I wanted to add a tag to it. However, Diigo does not have a separate "add tag" function. The only way to add a new tag is to share the same link to the group, again. However, it overrides the author - now the link says "Shared by Maria Droujkova" even though you linked it first. I hope it makes sense. We discussed it with Darren when I first started to use Diigo Groups: http://groups.diigo.com/group/math-links/content/can-you-add-tags-to-other-people-s-bookmarks-959243

Hi Maria, thank you for the clarification. I now understand your first comment.

Discusses a story in Genesis counting down (through negotiation) and asks for antecedents

If Abraham used multiplicative reasoning from 20 on, making the switch unnoticed because 20 to 10 is both additive and multiplicative, he could get down to 1 in just a few more steps!
