Amusements in Mathematics - A Timeless Classic of Math Puzzles

Henry Ernest Dudeney, English author and mathematician, became a legend with his math puzzle creations. He specialized in logic puzzles and math games. One of his greatest and most noted achievements, however, is his book, Amusements in Mathematics.

Amusements in Mathematics is one of the largest collections of puzzles with 430 brainteasers. All of the puzzles contained within the book are based on algebra, arithmetic, permutations, probability, plane figure dissection, properties of numbers and other mind bending math puzzles and math brain teasers. Critics hail it as "intriguing" and "witty." Amusements in Mathematics is said to be a "paradoxical production of one of the world's foremost creators of puzzles." It includes the puzzles as well as complete solutions.

Dudeney always had a passion for mathematics. He voiced his views very liberally. "A good puzzle should demand the exercise of our best wit and ingenuity," He said, "and although a knowledge of mathematics and of logic are often of great service in the solution of these things, yet it sometimes happens that a kind of natural cunning and sagacity is of considerable value."

When Dudeney wrote the preface to Amusements in Mathematics, he expressed his own views and opinions on puzzles in general. He also made several comments about puzzles that were in the book.

The difficulty of the math puzzles, according to Dudeney, were quite varied. Some math puzzles, particularly the ones that fell into the arithmetical and algebraically categories were very easy. He did warn his readers, though, that they should not overlook or dismiss puzzles that appeared on the surface to be very simple. He alluded to some of the math brain teasers as having traps or sublet pitfalls that could add a twist to the puzzle, giving it a degree of complexity and difficulty.

Dudeney also warned his readers to read the wording of the puzzles very carefully. He indicated that it would be in the reader's best interest to be prudent and wary when reading over the exact wording of the puzzles. He believed that this was a good exercise and a very good habit to cultivate. His beliefs were that it teaches exactitude and caution. Thus he added some twists and turns to the wording of his math puzzles to give his readers a little extra challenge.

The difficult math puzzles, according to Dudeney, could be quite challenging and some of the problems were, in his words, "very hard nuts indeed." His more challenging math puzzles, he explained, were advanced enough to warrant the attention of even expert mathematicians. And in some cases, even these expert mathematicians were left scratching their heads over some of Dudeney's math brain teasers.

Dudeney left his readers a vast selection of math puzzles so that there was something for everyone. He wanted readers to select puzzles in the book according to their individual taste. This resulted in a well rounded book that has math puzzles that are appropriate for nearly every member of the family. There are the simple problems for the youngsters and exceptionally challenging ones for the older more advanced family members.

Amusements in Mathematics by Henry Ernest Dudeney is a timeless classic. It is appropriate for family night, in the classroom or in a meeting of college professors. There is something to appeal to every taste and mathematical level. What's more, it is an entertaining, educational book that reminds us, even today, that math is fun.

4 Qualities You Need Have If You Want To Be A Great Teacher

Teaching is a difficult job and becoming a great teacher is almost a thousand times harder.

That is the simple reason why we can remember great teachers - they are as valuable and as rare as pink diamonds.

Overworked but underpaid, these great teachers view their calling as an opportunity - not as an obligation. They believe that to associate with young people is a rare privilege, to teach them is an inspiration and to lead them into a better future is a joy of the profession.

If you want to be one of those great teacher, here are the 4 most fundamental qualities you must have.

Have Sympathy

To have sympathy for your students is to have the ability to live, at least momentarily, in their life. A great teacher can re-live the memory his own childhood or has the power of imagination to see things through the eyes of his pupils.

A great teacher also take a matter of concern in the affairs of his students. To succeed as amazing teachers, we must have a strong passion to to help them. And that sometimes involves the actual doing of something by way of service.

Be Sincere

People say children and dogs are the great judges of sincerity. Guess what? They are absolutely correct. A great teacher is sincere in his work, believes in what he teaches and will do his best effort to the task in hand.

His class is his greatest concern, he meet his students because he loves teaching them and will always be available for counsel at any time. Because he is sincere in his work - he teaches with enthusiasm.

Be Optimistic

Optimism is contagious.

Look for the good things in your students. Even the weakest or the naughtiest one have some admirable qualities in them.

Be friendly, do not be so serious in your job that you forget to be human. Yes, too much friendliness can be used by the students as a license for mischief. However, great teachers know when to exert order and when to apply cheer.

Remember, cheerfulness is the best key to the human heart.

Have Vitality

The days where a stern teacher is respected has been long gone. Not having enough role models, young kids nowadays demand a teacher or leader who is energetic and enthusiastic . A great teacher fills in the role perfectly.

He knows that children like to have a teacher who the have a certain vigor of attack that appears to go directly to the point, putting at rest all other things and making discipline simply unnecessary.

That is what 20th century students seem to like.

There are many other contributing factors that make a great teacher. However the above four steps are believed to be the key or fundamental to be one. Follow the steps, acquire the abilities and one day you will also be a teacher that your students may remember for their entire life.

Teaching Patriotism in Elementary Schools

Patriotism is a growing concern in our nation today. One of the ways to teach children patriotism is to have them be in an informative play or program. Many schools and teachers are looking for programs to fit this description that are easy to put on and take very little practice time to present. With all the teaching and testing that teachers are required to do for the “No Child Left Behind” idea. It has left them with little time to do the creative programs for their students. Even though these are the activities that children will remember they are the ones that are being eliminated from schools.

Patriotic programs also need to teach and educate students in a creative way about their country. The programs or plays show them just what a priceless gift freedom is for them to celebrate and embrace. Teaching them about respect for their flag, country and other patriotic symbols such as the Statue of Liberty, The Liberty Bell, The Washington Monument, and the Lincoln Memorial is important for patriotism to take root in young children.

There are many holidays that students could participate in patriotic programs. Just a few are Constitution Day in September, Veterans Day in November, Election Day, in November, Pearl Harbor Day in December, Columbus Day in October, Martin Luther King Jr. Day in January, Presidents Day in February, Memorial Day in May, and of course July 4th in July. All of these times are special events that call for some patriotic program and it helps us appreciate our freedom more. Another more recent day is 9/11 in September to remember those people who serve our country

Nothing instills patriotism more than a good patriotic song. There are so many on the market today that it is not hard to find something to fit any patriotic program. Another must for a patriotic program is a good power point presentation showing our flag, or maybe even all the flags that have flown over the United States. A good power point can make students feel how important that flag really is to them. One of the things that I like in programs to teach patriotism is to always start the program with the scouts posting the Colors of the United States of America. One years we had taps played and the students really enjoyed that, also.

To summarize some of the most important parts for a patriotic program is:

Take the time to do a patriotic program at least one a year

Talk about the symbols that represent our country

Choose an appropriate day to celebrate

Include patriotic music

Include pictures

Post the Colors and Retrieve the Colors of the United States of America
