This gaping void has now been filled by Wolfram Research's package The Mathematical Explorer The Mathematical Explorer is a stand-alone custom Mathematica product designed for anyone who has ever delighted in exploring the unexpected pleasures of mathematics. As readers of Martin Gardner's "Mathematical Games" columns are aware, one of the joys of recreational math is that no degree in higher math is necessary; a deep appreciation for the subject can be obtained with just a little basic algebra and a sense of fun. The Mathematical Explorer represents a compilation of topics from the books and articles of Stan Wagon, noted mathematician, author, and proponent of the

I followed it up with a Math Games column about Sudoku Variations . An unsung hero in this is Wei-Hwa Huang, who sent me an enormously helpful list of Sudoku types . Alan O'Donnell sent solutions (and corrections) for every puzzle in the column "I think I can say I've truly conquered this genre of puzzle now." Bob Harris mentioned that the Geometric Sudoku are also known as Latin Squares , with only one given per region. Bob Harris: It's amazing to me how much more difficult generating an 8x8 puzzle seems to be than a . Here's an 8x8 (below). Probably pretty hard, but at least 3 cells can be labeled quickly and a couple other matches (this cell is the same as this other cell) can also be identified.

34. PuzzleCLUB - Visual Brainstorms 2 Popular interest in recreational math and science has not been this strong since almost a century ago when Sam Loyd was America s foremost puzzle inventor, http://www.puzzles.com/PuzzleClub/Articles/VisualBS2Intro.htm

Visual Brainstorms 2* by Martin Gardner e are living in a time when good, fundamentally sound education is essential to our future. The onset of the information age presents entirely new challenges to us as a society in the 21st century. Both children and adults are being asked to adapt to new technologies, to learn new skills, and to think in new and smart ways. Clever brainteasers such as those found in the Visual Brainstorms cards are designed to introduce you to smart ways to think. Kids will have fun learning while chuckling at the amusing way the questions are illustrated; teachers will enjoy the variety of problems to present to inquiring minds; and adults will discover that they are often on common ground with their younger counterparts as they struggle to organize their thoughts and arrive at a solution to the question. As you will find, V isual Brainstorms 2** will spark your own curious mind to think in new ways and to join in the celebration of learning. Here is an overview of all the places this deck will take you on your journey of learning, as well as a few comments on the connections the cards make to today's evolving world of math and science.

Home Education Magazine January-February 1997 - Columns Older Kids - Cafi Cohen Rethinking Midschool/High School Math M-A-T-H. What thoughts come to mind with the word MATH? The three R's. A government school "required subject," according to many state statutes and some local regulations. An essential topic in any homeschool. Past that point, what official guidance are you given for teaching math? Often, none. What you cover and how you cover it is up to you. In the absence of specific directions, many homeschooling families pursue what I call School Math. School Math is how most parents studied math when they attended school; and it is how most schools still teach math. School Math involves textbooks, workbooks, and exams. Older kids pursuing School Math study the subject sequentially in other words, arithmetic, followed by algebra, then geometry, second year algebra, trigonometry, and so on. Those using a School Math program must always "show all the steps" and reason exactly like the author of the text reasons. Alternate approaches to problem solving are unacceptable. Getting the right answer is emphasized, often to the exclusion of understanding the process. School Math texts often include unrealistic problems. Typical is the following. A 20-ft. telephone pole falls across a street and the two ends extend one foot and three feet either side of the street. How wide is the street?
