Face Memory Game

It was interesting to wander around the Washington.edu site and check out the different memory tests.

I will be using some of the games to help my students learn memorization strategies, specifically for addition and multiplication facts given that surprisingly many high school clients do not know these facts.

My elderly clients often have trouble remembering new facts, especially in regards to new technology. "Why on earth would you click on the Start Up button to turn your computer off?", was one of the comments I heard. There are physical changes that occur in the brain as humans age that make it more difficult for many people to learn new things, so it is not surprising that it takes some practice to learn how to program TIVO.

On the other hand, my teenage clients are able to remember all sorts of facts: phone numbers, how to use the many functions of their graphing calculators and cell phones, how to download and keep track of thousands of songs, and how to manage their social networking pages yet these same students cannot remember the product of 6 and 7. Even more disturbing is the fact that a number of the parents are likely to tell me that their children are incapable of memorizing their math facts rather than admit that their child might be a bit lazy or unmotivated to do the work.

Memorization takes work. And some memorization, such as math facts, may be tedious and unpleasant work. It has been my experience that most of the students lacking math facts are UNWILLING to do that work.

Daniel Tammet Can Recite 22,514 Digits of pi From Memory

From Scientific American: Daniel Tammet can recite 22,514 digits of pi. He holds the European record for such a feat. So, I guess there is a competition? The article covers an interview with Mr. Tammet in which he discusses memory and I.Q. tests.


As I peruse the internet I am fascinated with the many different ways people spend their time. How long did it take Daniel Tammet to memorize that many digits of pi?

Typing pi to 22,514 digits in a continuous (no spaces) stream, in a Word document with smaller than average margins, using Times New Roman, size 12 font, single-spaced, would take 5 or 6 pages of paper.

An interesting relation: Suppose Mr. Tammet can recite 2 digits per second (a reasonable estimate). Then it would take approximately 3.13 hours to recite 22,514 digits. In other words, it would take close to pi number of hours to recite pi to 22,514 digits.
