These are some handouts I've written over the years. The Math and Problem Solving sections of my personal blog might also be of interest. See also Recommendations for other authors I like, as well as my geometry book for a comprehensive textbook in Euclidean geometry.

What is the number of nickels which can be placed around it so that each is tangent to it and to two others? Stated as puzzles, they are found in the oldest written records.

An Egyptian Papyrus, dating back to n. Here is a charming example from Indie recorded about 4. The remaining six lotuses were given to the venerable preceptor. Tell quickly the whole number of lotus flowers. This sounds more exciting than: Solve the equation eit tied but of course our way of stating the problem has an overriding ad- vantage: it makes the solution easier.

The glory of elevating mathematics from the level of problem solv- ing to that of a science belongs to the ancient Greeks. But these Greek mathematicians did not neglect the art of inventing and solving prob- lems. Three of their proposed geometric problems remained challenges to mathematicians until the 19th century.

Since the time of the Greeks, such problems have stimulated the growth of mathematics and led mathematicians to invent new methods tnd to develop new concepts. On more modest but equally important level, such problems have provided an unexcelled training ground for young mathematicians. But problem-solving never was the exclusive domain of professionals. At all times it provided intellectual stimula- tion and joy for many professionally outside the field of mathematics.

During the Renaissance in Italy problem-solving became a compet tive sport and publie contests between mathematicians were not un- common. Sometimes the competitive spirit led to excesses. For example, in the 16th century, Tartaglia, the winner of such a contest, had to flee town to escape violence at the hands of the fans of the local cham- pion.

The subject of this particular contest was cubic equations and, in preparing for it, Tartaglia discovered important formulas for solving them. In our own day mathematicians still compete with each other in solving problems—less publicly, less violently, but perhaps with the same intensity.

The end of the 19th century saw the beginning of organized com- petitions among secondary school students. The so-called Edtvos Competitiont in Hungary begun in is justly famous; it has probably played its part in producing so many superior mathemati- cians and physicists from this small country.

In the Soviet. It is one of the three major mathematical organisa tions in America the other two being the American Mathematical Society, chiefly concemed with mathematical research, and the Na- tional Council of Teachers of Mathematics, concerned with the content and pedagogy of elementary and secondary mathematics. Its journal, The American Mathematical Monthly, is famous for its elementary and advanced problem sections. It became national project in , receiving in that same year co-sponsorship by the Society of Actuaries.

In more than , students from 5, schools participated in the program. The contest is conducted in nearly every state and territory of the U.

Readers who find these problems too easy are advised to try the problem sections of other NML books and to await additional NML problem books which are now in prepara- tion, Part I of each examination tests fundamental skills based on con- ceptual understanding, while Parts II and III probe beyond mere reproduction of class-room work. For the ten years this contest was conducted, only three people scored perfectly ; a score of 80 oF more places a contestant on the Honor Roll.

Charles T. B reaches Poughkeepsie and at once turns back meeting A 12 miles from Poughkeepsie. There are then left two boys for each girl. After this 45 boys leave. There are then 5 girls for each boy. The number of girls in the beginning was: A 40 B C 29 D 50 E none of these John ordered 4 pairs of black socks and some additional pairs of blue socks. The price of the black socks per pair was twice that of the blue. The ratio of the number of pairs of black socks to the number of pairs of blue socks in the original order was: A B 21 Ce 12 Bus The foot of the ladder is 7 feet from the base of the building.

An equilateral triangle is drawn with a side of length a. A new equi- lateral triangle is formed by joining the mid-points of the sides of the first one.

A Every point on the locus satisfes the conditions and every point not on the locus does not satisfy the conditions. B Every point not satisfying the conditions is not on the locus and every point on the locus does satisfy the conditions.

He declined the prize money. In dimension 2, a sphere is characterized by the fact that it is the only closed and simply-connected surface. It is central to the more general problem of classifying all 3-manifolds.

In the US, the first Annual High School Mathematics Examination was offered in First confined to the Metropolitan New York area, it became a national contest in From the beginning, the contest had a practically impossible goal to accommodate as many students of various abilities as possible. This goal dictated the format of the contest.

Written in English. This study aims to analyze the effectiveness of learning materials oriented on problem-based learning models, the improvement mathematical problem solving ability and students' metacognition ability. Learning materials that developed are lesson plan, student book, student worksheet, mathematical problem solving ability and students.

Домой? - ужаснулся Бринкерхофф. - Вечером в субботу. - Нет, - сказала Мидж. - Насколько я знаю Стратмора, это его дела. Готова спорить на любые деньги, что он .

Если я и полицейский, то уж точно не здешний, как ты думаешь. Эти слова, похоже, озадачили панка. - Меня зовут Дэвид Беккер. - Беккер улыбнулся и над столом протянул парню руку. Панк брезгливо ее пожал. - Проваливал бы ты, пидор.

Рыжие волосы, - повторил Беккер, понимая, как глупо выглядит. - Простите, у нас нет ни одной рыжеволосой, но если вы… - Ее зовут Капля Росы, - сказал Беккер, отлично сознавая, что это звучит совсем уж абсурдно. Это странное имя, по-видимому, не вызвало у женщины каких-либо ассоциаций.

Сьюзан понимала, что, по всей логике, именно ей предстояло решить эту задачу. Она вздохнула, надеясь, что ей не придется раскаиваться в том, чем она собиралась заняться. - Если все пойдет хорошо, то результат будет примерно через полчаса.
