No. 502640 Avoid the Mathematics Demons Poster................................................ $5.95 Classic designs from the decorative pages of the Koran and beautifully tiled mosques proclaim not only the artistic discipline of the Arab people but also their appreciation and skill in mathematics. Inspired by a fervent desire to contemplate the mystery of the mercy and greatness of Allâh, the Islamic calligraphers produced magnificent patterns based upon geometry, complex symmetries, and algebraic relations. During the 8th century A.D., under caliph al-Mansûr (712-774 A.D.), Baghdad dominated the world of mathematics and science. The great Hindu works of astronomy, mathematics, and medicine were translated into Arabic and studied. Ancient Greek classics were saved for our time by the work of many prominent Arab scholars.

Why Study?

What al-Mansûr began in his day produced a long tradition of learning at Baghdad. His successors produced a truly golden age for Arabic mathematics and science during the 9th and 10th centuries. The eminent mathematicians and scientists of the day came to Baghdad to study geometry, number theory, algebra, and trigonometry. Renowned observatories were built, med-

icine was skillfully practiced, and a celebrated legacy of learning from ancient times was preserved and passed into Europe. It was the prodigious intellectual tradition of the Arab world that made possible the advances in mathematics in our own time. Perhaps, the most well known influence of Arabic mathematics on Western mathematics is found in the word algebra derived from the famous Arab mathematician Mohammed ibn Musa, alKhowârizmî. His al-jabr w'al muqâbalah (c. 825 A.D.) was the first unified organization of the subject of algebra. One of the least known contributions of Arabic mathematics was fundamental for the development of Western mathematics. In the early 15th century, Arab scholars made use of decimal fractions long before their introduction into Europe. In his Treatise on the Circumference (1430 A.D.), the director of the observatory at Samarkand, al-Kashî, advanced precisely the value of π to sixteen decimal places. In the innovative decimal form, with a space instead of the modern dot, he wrote the value as : 3 1415926535898732.

Classical Korean mathematics is closely tied to the ancient Chinese system of calculating rods. Although invented in China as early as the 4th century B.C., the system continued to be used by Korean scholars beyond the 11th century A.D. when it began to lose favor in China. Korean mathematicians transmitted the calculating rods to Japan in the 6th century A.D. Furthermore, Korean scholars preserved the understanding of this remarkable form of mathematics by using it into modern times. Korean mathematicians used calculating rods to solve a wide range of problems from simple arithmetic to advanced concepts like solving systems of linear equations and polynomial equations up to degree ten. Korean scholars solved such advanced problems several centuries before they were solved in Europe. A classic set of calculating rods usually consisted of 271 small bamboo pieces about 4 cm long and one-half cm in diameter. Red pieces represented positive numbers and black rods stood for negative numbers. The central picture on this poster depicts two Korean scholars using the calculating rods on a rectangular grid or board.

Lam na ed 17” x 22”

Calculating rods are based on the decimal system with a set of nine digits as shown in Table 1. For convenience, mathematicians used two forms: one for odd powers of ten (10 1 = 10, 10 3 = 1,000, and so on) and another for the even powers of ten (10 2 = 100, 10 4 = 10,000, and so on). This served as a check against error. Rod numerals have no special symbol for place value. They are read from left to right with the place value determined by the relative position. When placed on a grid, the calculating rods can be used to indicate zero place value by leaving a square empty. See the examples in Table 2.

The Dineh (or the people) are remarkably inventive Native Americans known to most people outside their culture as the Navajo. About 1690, they adapted into their life the art of weaving wool. Today, Navajo rugs are among the best and most highly esteemed in the world. Traditionally, Navajo women raised the hardy Spanish churro sheep. From these animals, they obtained both white and brown wools for their weaving. Many patient hours were spent producing the yarns which included locating natural materials for the dyes sometimes used. Even the looms were made by these hard working women. Today, the art has developed into thirteen regional styles with varying materials and techniques. The Math of the Dineh is to be found in the artistic rugs produced by Navajo women. But, how is to be found? It is unlike the European style developed from the seventeenth century. Contemporary mathematics has developed into an abstract theory in imitation of Euclid's classical geometry. The Navajo mathematics is a creative process visualized in the mind of the weaver. The results are beautifully seen in a completed rug.

Mathematical tradition in Japan is ancient. During the reign of Empress Suiko (592–628 A . D.), bamboo rods, chikusaku, were introduced to speed calculations. The rods were circular in cross section, but were soon made square to prevent rolling. These improved calculating rods were called sangi. The woman seated at the table, depicted at the center, uses the sangi to solve a problem on a rectangular grid known as a sangi board.

In Block B, addition on the soroban is shown. Unlike written computation, the operations are performed from left to right. In the example, the sum of 135 and 29 is required.

Making of a Navajo rug requires considerable skill in estimating the materials needed to produce both dyes and yarn. This mathematical skill is found among the many cultures of the world in producing their artistic and practical works. What is perhaps not commonly realized is that Navajo women have tremendous spatial visualization. They do not use written patterns. Each weaver visualizes the complex design of her entire rug and executes the work from the mental conception alone.

India developed a lattice method of multiplying numbers. The earliest written record of this method, called kapâta-sandhi, occurs in Hindu works of the ninth century A.D. The method is illustrated in the side panels of this poster. To understand the kapâta-sandhi method of multiplication, consider the multipliDesign and text by Lawrence Swienciki, Ph.D. cation of 27 395 in the upper window of the left-side panel. First, the number 27 is positioned above the lattice and 395 is positioned to the right of the lattice. Second, each box with a diagonal is filled with simple partial products that correspond to the numbers outside the lattice. For example, in the upper-left square the 0 and the 6 are a result of multiplying the 2 in the first column with the 3 in the first row. Because the product 6 has only one digit, it is necessary to enter 0 in

The ancient Maya have long intrigued the modern world. Their great pyramids and temples, built between the third and tenth centuries A.D. of the classic Maya era, still puzzle scientists. Hundreds of archaeological sites with beautiful sculpture and intricate hieroglyphic text are scattered over a region covering Belize, Guatemala, parts of Honduras and El Salvador, and several Mexican states. For example, the central panel of this poster depicts a scene carved over several limestone lintels at the site of Yaxchilán, located in Chiapas, Mexico. On October 28, A.D. 709, the King of Yaxchilán, Shield Jaguar, honored his wife, Queen Lady Xoc, for her sacrificial bloodletting offering. Of all Native American mathematical systems, that of the Maya is the most complex. In the upper-left panel, the common Maya numerals are shown. In this base-20 system, any whole number can be written with three symbols: the dot (•) for 1, the bar ( ) for 5, and the shell ( ) for 0. The numbers 0 through the upper triangle of the box to fill both spaces of the box. In the box with the 19 are illustrated in the first five rows of blocks. The next number, 20, requires digits 1 and 8, the product 18 was formed by multiplying the 2 in the first column a new place value. Notice that units of place value increase in multiples of 20. by the 9 in the second row. Similarly, other boxes are filled with corresponding So, instead of 1s, 10s, 100s, and 1000s, the Maya system used 1s, 20s, 400s, partial products. 8000s, and so on as units of place value. For example, 48 is understood as eight 1s plus two 20s. The number 400 requires a third place value: it is read as no After all of the boxes are filled, the numbers are added diagonally from the lower1s, no 20s, and one unit of 400. right corner and placed in the boxes below and to the left of the lattice, proceeding in a clockwise direction. First, the 5 in the third row of the lattice is entered in the box below the lattice because there are no other digits forming a diagonal with it. Next, the 3, 3, and 0 are added. The result, 6, is entered in the left square below the lattice. Note that 6 is a single digit. But the next diagonal sum of 1, 8, 6, and 1 equals the two-digit number 16. Only the 6 is placed in the lower square to the right of the lattice. The 1 is carried and added to the next diagonal sum. The process continues until the correct answer, 10,665, results from all the squares being filled. Seven other examples are completed in the side panels for you to verify. The panels to the left and right side of the text have square lattices that can be multiplied in the manner just described. Complete the lattice multiplication and verify your answers.

According to legend, high in the Andes Mountains of twelfth-century Peru, four brothers and four sisters set out for the conquest of a new homeland. They called themselves Inca, lords appointed by their god Viracocha to conquer and bring civilization to the world. Led by Manco Capac and his sister Mama Oello Huaco, the Inca set upon their neighbors with great tact and political cunning, using deceit and bribery as well as military force to secure the rich agricultural valley of Cuzco.

Addition and subtraction with the calculating rods involves a type of perception similar to making change with money. Depending upon its relative position, a single rod can be visualized as a one or a five. In adding 7 plus 8, for example, the result 15 can be more directly manipulated than memorized. Similarly, the multiplication described above has a different feeling on a calculating board than with a modern paper and pencil algorithm. Because the ancient scholars had more perception of the place value during the process, they likened multiplication to the driving of a chariot. The multiplier and multiplicand were the wheels. They controlled the partial products between the two wheels.

In the upper right panel of this poster, the solution of the system of two linear equations in two variables is outlined in four steps. The two equations are 2x y 7 and x 2y 8. In step 1, each equation is set down in a vertical column. In this context, the first row entry is the numerical coefficient of the x; the second row, the y; and, the third row, the constant. The solution is developed in the diagrams with the red rod numerals representing positive numbers and the black rod numerals indicating negative numbers. The four steps are equivalent to modern matrix algebra as applied to columns rather than rows. Three basic rules apply: (1) any two columns can be interchanged; (2) the values of any column can be multiplied by a non-zero constant and replace the corresponding elements of the original column; (3) the corresponding values of one column can be added to another column to replace it. In the example, the final step requires the columns be interpreted as x 2 and y 3.

In the two examples of the linear system on this poster, the answers are integers. However, the Korean scholars solved problems with fractional answers as well. They developed many sophisticated methods of solving these and other advanced mathematical problems.

The Maya defined the first day of history by postulating a first Calendar Round date of 4 Ahau 8 Cumku and projecting its existence thousands of years back in time. Transcribed into the Gregorian calendar, this date corresponds to August 13, 3114 B.C. With the first day of history defined, the Maya could use another system to specify any important date in Maya history. They could give the Calendar Round date and the long count, the number of days that elapsed from the beginning of history to the current date. In the lower-right panel, a long count from the palace stairs at Palenque is transcribed. The date at the bottom, 8Ahau 13 Pop, is the historical Calendar Round date recorded. The upper-left glyph specifies that the information to follows is a long count. The other five glyphs specify periods of baktuns, katuns, tuns, uinals, and kins. The sum of all of these periods means that 1,356,100 days have elapsed from the beginning of history to the recorded Calendar Round date of 8 Ahau 13 Pop. Maya scribes calculated the number of days between Calendar Round dates or projected Calendar Round dates foreward or backwards in time to document important dates. Can you suggest other ways the Maya could have specified Calendar Round dates in their system?

The lower right panel of this poster outlines four major steps of the solution of the linear system: x y z 2; 2x 3y z 11; and x 2y z 8. To fully appreciate the solution, the student is advised to construct a simple grid and set of calculating rods. While this method is equivalent to the modern matrix algebra method, the calculating rods utilize more perception. However, since the pieces on the board are being changed during the process, there are no written steps that can be checked.

The highly complex expression of known Maya mathematics was primarily concerned with calendar dates, which the Maya used to document the activities of their royalty and divinities. The Maya devised a 52-year calendar, called a Calendar Round, composed of two cycles: a 260-day Sacred Round and a 365-day Vague Year (an approximate solar year.) The Sacred Round consisted of the numbers 1 through13 paired to the 20 named days illustrated in the lower-left panel. The Vague Year consisted of 18 months of 20 nameless days and a final month, Uayeb, with 5 unlucky nameless days. The month glyphs are shown in the upper-right panel. The two cycles worked as meshed gears. Any particular date in the 52-year cycle could be uniquely specified by 4 symbols, as in the Calendar Round date of 4 Lamat 15 Xul. However, after 18,980 days, the same date occurred again. Time repeated itself. To specify dates, the Maya counted the number of days between events (Maya scribes used many different glyphs to express the same idea. The following examples represent only a few of the glyphs found at various Maya sites.) The kin, or day, was the basic unit of time (glyphs C). Higher units were the uinal of 20 days (glyphs D), the tun of 360 days (glyphs E), the katun of 20 tuns (glyphs F), the baktun of 400 tuns (glyphs G), the pictun of 8000 tuns (glyphs H), the calabtun of 160,000 tuns (glyph I), and the kinchiltun of 3,200,000 tuns (glyph J). These basic units of time were combined with numerals in various ways. In glyph A, the figure on the left is identified as the number 17, while the toad figure to the

Korean scholars memorized the times tables up to 9 times 9 in a famous rhyme. A more general example of multiplication is illustrated in the lower left panel of this poster. The problem 49 24 is set down in the first step. The multiplier 49 is placed in the first row. The multiplicand 24 is placed in the last row, but shifted left so that its last digit is aligned with the first digit of the multiplier. In step 2, the first digit of the multiplier is used to multiply each of the digits of the multiplicand. The partial products 800 and 160 are set down on the second and third rows. The sum 960 is made on the fourth row and is carried into step 3. In step 3, the multiplicand is shifted to the right so that its last digit is aligned with the second digit of the multiplier. The sum 960 is moved up to the second row. The digit 9 of the multiplier is applied to multiply each digit of the multiplicand. The partial products 180 and 36 are set down on the third and fourth rows. The final answer 1,176 on the fifth row is completed by adding the second, third, and fourth rows.

Africa is a vast continent with many interesting nations and a variety of beautiful customs. Its mathematics is often used for practical and artistic purposes because farming, raising animals, trading goods, and creating art have long been important to African activities. The Asante people of what is now Ghana were once a rich and powerful nation who used gold as a form of money. They invented a special scale and a system of weights to measure quantities of gold dust. The weights were artistic brass castings shaped as birds, animals, and humans posed in various activities of work or as bold geometric shapes. The center panel depicts an Asante king and his official keeper of weights, dressed in their traditional kente cloth. They are shown exchanging goods with an Asante chief and his family. The side panels show examples of the types of brass weights the royal official would haved used in such a transaction. For the Asante people, the design of their brass weights and the patterns of their clothing went far beyond function and beauty. Design reinforced the values of Asante culture. For example, in the left panel the weight showing two crossed crocodiles encouraged families to

Africans often use hand gestures when speaking. Some Africans simultaneously pronounce and gesture numbers. The center panel shows the Asante chief gesturing a number. The center panel also shows an older man teaching a variation of a board game that is popular throughout Africa. (The ornate game board shown above is the type used by royalty or the wealthy.) In all of the game’s many forms, two players fill the board’s cups with seeds or stone pieces. The pieces are distributed and captured as the game progresses. Such games are exciting and sharpen arithmetic skills. The student sitting to the left of the teacher holds another board game, which requires the use of logic and sharpens geometry skills. This popular Asante version of the game is similar to that used by the ancient Egyptians over 3000 years ago at the temple of Qurna. Each of two players has four markers, and each set of markers is a different color. The players place the markers down on the board’s grid lines, with the goal of creating a pattern of three like markers. Achieving three in a row is how the game is won. The Chokwe people of Angola, especially the Chokwe women, are well known for the beautiful

traditions: complex geometric sand drawings. An elder sets down a grid of dots by marking the sand with his fingers, then traces a pattern around the grid. The Chokwe sand drawings can be studied as mathematical networks. In network theory, a Chokwe sand drawing can be described as traceable if it can be drawn as a continuous path without lifting the finger from the drawing or retracing any segment already drawn. Diagram 1 is traceable, but only by starting at point A and finishing at point B (or vice versa). Diagram 2, not a traditional Chokwe design, is not traceable. Diagram 3 is traceable from any starting point. Can you determine from these three examples what makes a path traceable? The Chokwe attached special meaning or stories to their drawings. Diagram 4 represents two kumbi birds, and diagram 5 is the initial stage of a drawing depicting a lion with two cubs. Traditionally, a storyteller would add three tails and a head to complete the figure. Are these drawings traceable?

The Gothic cathedrals were among Europe’s greatest cultural achievements during the Middle Ages. Not only were these soaring edifices examples of religious devotion and political organization, but they were also superb applications of mathematics. The side stained glass windows of this poster show a popular mathematical device of the same period, the line abacus. The line abacus was a popular calculating table used in Western Europe for several hundred years. During the fifteenth and sixteenth centuries, it reached its widest use in Germany. The line abacus was a ruled grid placed on a table. Markers were positioned on or between grid lines to compute sums, differences, products, or quotients.

The upper left side window of this poster depicts a typical column of a line abacus. As shown, the place value is indicated by the lines and the spaces between the lines. Numbers are represented by placing markers (shown here as yellow dots) on or between the lines. Note that the cross on the thousands line serves as a guide in the same way that the comma is used

Make a Difference

Be honest Teacher...What do you make?

Dare to Dream Robert Marble’s delightful whimsy. 22” x 17”.

I make kids work harder than they ever thought they could. I can make a C+ feel like a Congressional Medal of Honor and an A- feel like a slap in the face. I make kids sit through 40 minutes of study hall in absolute silence.

You want to know what I make?

I make kids work harder than they ever thought they could. I can make a C+ feel like a Congressional medal of honor and an A- feel like a slap in the face. How dare you waste my time with anything less than your very best.

I make kids wonder, I make them question. I make them criticize. I make them apologize and mean it. I make them write, write, write. And then I make them read. I make them spell definitely beautiful, definitely beautiful, definitely beautiful over and over and over again until they will never misspell either one of those words again. I make them show all their work in math and hide it on their final drafts in English. I make them understand that if you’ve got this, then you follow this, and if someone ever tries to judge you by what you make, you give them this.

I make kids sit through 40 minutes of study hall in absolute silence. No, you may not work in groups. No, you may not ask a question. Why won’t I let you get a drink of water? Because you’re not thirsty, you’re bored, that’s why. I make parents tremble in fear when I call home: I hope I haven’t called at a bad time, I just wanted to talk to you about something Billy said today. Billy said, “Leave the kid alone. I still cry sometimes, don’t you?” And that was noblest act of courage I have ever seen. I make parents see their children for who they are and what they can be.

Let me break it down for you, so you know what I say is true:

I make a difference. Now what about you?

Tactile Algebra

Tactile Algebra is a fun and interactive way to help students understand the process of solving equations. Students use manipulatives to “move” algebraic terms from one side of an equation to the other, thus bridging a visual connection to the abstract process of solving equations. Tactile Algebra includes reproducible sheets for students to record the necessary steps taught in traditional ways, but with an added kinesthetic connection along the way. There are also “Speed and Agility” sheets for students to practice the new skills once the manipulatives are no longer needed. Start making Algebra fun for students using Tactile Algebra for introduction or for remediation. i 1 No. 653125 Tactile Algebra Game ��$19.99
