THE MATH INSIDE DANCES, SONGS, STORIES, POETRY AND GAMES Alleli C. Domingo Institute of Mathematical Sciences and Physics College of Arts and Sciences University of the Philippines Los Baños +639174010594 allelidomingo@yahoo.com ABSTRACT For mathematics education to be relevant in the 21st century, it must offer an integrated, comprehensive and extensive view of the world. As an alternative to the fragmented systems so prevalent today, quantitative reasoning should enable learners to think broadly and across disciplines. Viewing math from multiple perspectives could go a long way to helping pupils overcome their fear of what they may have wrongly perceived to be a difficult, unnatural pursuit. Illustrative examples are presented to highlight the presence of mathematical concepts involved in dances, regional songs, stories, poetry and indigenous games. Possible activities using movement and rhythm are suggested to make learning much more fun. Engaging the children in their mother tongue naturally creates spontaneity and reduces math anxiety. This experimental step taken towards an inter-disciplinal approach to the teaching of mathematics is a recognition of the role played by multiple intelligences in today’s classrooms and a response to the need of making mathematics accessible for all students with varied cultural backgrounds and learning styles.

INTRODUCTION From the mighty pen of Francisco Baltazar flowed the following lines: “Natarok ko ang lalim ng pilosopiya Aking natutunan ang astrolohiya Natantong malinis ang kataka-taka At mayamang dunong ng matematika.” - Talata 216, Florante at Laura What is it in mathematics that appealed to the sense of wonder of a brilliant poet? In his book “The Math Gene” mathematician Dr. Keith Devlin, argues that “mathematics is not about numbers, but about life. It is about the world in which we live. It is about ideas, and far from being dull and sterile, as it is often portrayed, is full of creativity. It is the science of patterns.” Consider the patterns explored in some branches of mathematics: in logic we study patterns of reasoning; in arithmetic, we work with patterns of number operations; in algebra, we examine patterns of finding unknown quantities; in geometry, we Ed investigate shapes and sizes; in trigonometry, we examine patterns of triangles; in calculus, we deal with patterns of changes in quantities; and in statistics we are concerned with patterns of data analysis. Dr. Devlin expounded that “doing math” involves all kinds of mental capacities such as numerical reasoning, quantitative reasoning, linguistic reasoning, symbolic reasoning, spatial reasoning, logical reasoning, diagrammatic reasoning, reasoning about causality and the ability to handle abstractions. He observed that such mental abilities, developed by our ancestors thousands of years ago to survive in a sometimes hostile world, are basic attributes important to our daily lives. When mathematics is defined as the science of patterns, and doing math is viewed as reasoning about patterns, the presence of mathematics is keenly perceived here, there and everywhere. As gleaned from the Greek root word mathematikos (which means “inclined to learn”), math is a “learnable knowledge” that can be made accessible to all, whatever language that is in use. 2. SHALL WE DO THE MATH DANCE? In 1978, C.R. Fowler, in Dance as Education, pointed out that “the basic components of dance – patterns, lines, form, shape, time, rhythm, and energy – are pivotal concepts in may other curricular areas and can therefore be integrated with and enhance mathematics and the social sciences as well as the language arts.” Dance is geometry in motion. A unique integration of math concepts and dance skills that maintains the integrity of both disciplines is modeled by “Math In Your Feet” (MIYF) – a standards-based, weeklong artist residency program in the USA for 4th and 5th graders. MIYF physically and mentally challenges students to experiment with traditional percussive dance while focusing on an inquiry into patterns, algebra, geometry, and problem solving. MIYF puts discrete math concepts like angles, degrees, center, zero, origin, symmetry, sequence, and directions directly into students' feet and bodies. In general, MIYF takes what students know and puts it in a new context. This process connects previously unrelated ideas together, directing students to the crossroads where disciplines meet. An episode of Discoveries and Breakthroughs Inside Science (a syndicated science and engineering news service for local television newscasts all over the United States) in May 2008 featured the math dance program of mathematician-dancereducator Karl Schaffer, Ph.D., and actor-dancer-composer-teacher Erik Stern, who described how this approach can help students who have trouble relating to mathematics. Mr. Stern observed that “many math-phobic adults and children are put off by math because they are given symbols before they have a real solid experience on which to base these on.” To which Dr. Schaffer added “For many people, having a kinesthetic experience of an abstract idea is extremely helpful in understanding what that abstract idea is.” In this alternative way of knowing, mathematical symbols and patterns are translated into choreography and conversely dance patterns are translated into math. In a paper presented at the April 3-4, 2008 Science Summit held in the University of the Philippines Baguio, Dr. Christopher C. Bernido of the Research Center for Theoretical Physics, Central Visayan Institute Foundation, referred to the circle as a rich, unifying concept. As a synthetical level example to illustrate a feature of the Dynamic Learning Program that he and his wife Dr. Marivic Carpio-Bernido are administering in Jagna, Bohol, he enumerated the topics that can be discussed based on the circle such as Venn diagrams, circumference as a linear function, circular area as a quadratic function, coordinates of points on the unit circle, circular functions, polygon of infinite sides, nontrivial topology, wave functions and simple harmonic motion. The simple closed curve that is the circle is fundamental to dancing. It is the dance formation that must been used for the longest time. There is a wealth of resources on circle dances, which speaks of the universality of the very ancient tradition for the celebration of special occasions, community-building and bonding. Up to this time, cultural circle dancing is alive and well in the Philippines and in many parts of the world The wholly intuitive performance of the Balinese candle dancers continue to impress international audiences. The candle dance trick involves rotating the hand, palm-side up by 360 degrees, resulting in an arm twist. To undo this arm twist, a second 360degree rotation in the same direction is needed. That a 720degree turn is the identity instead of 360 degrees is also instinctively demonstrated by Filipino dancers in their Binasuan dance routine. Children can experiment with the movement and prove that they can extricate themselves from orientation entanglement. A glass filled with colored liquid is held over the right hand straight out in front. Then it is brought to the left, and in a counterclockwise direction under the underarm, it is brought around front in a circular, 360 degree rotation with the elbow straight up in the air. To get out of the awkward twisted arm position, the counterclockwise movement must be continued, but this time the arm must be swung around over the head. At 720 degrees, the hand is back to its original straight arm, palm up position, with no drop of the colored liquid spilled. All the dance steps of the delightful traditional Filipino bamboo dance Tinikling are combinations of only three basic 4/4 steps, called singles, doubles, and hops. The choreography can be altered by simply changing the combinations. A new formation can be attained by rotating the poles through varying degrees. Listed in Table 1 are culturally-rich illustrative examples of mathladen creative movement activities that can be undertaken inside and outside the classroom. Ed Table 1.

The students get to see a world beyond the walls of the classroom as they try different dances. Such exposure paves the way to cross-cultural understanding and peace education 2. HEARTFELT MELODIES Filipinos are musically-gifted. The numerous prestigious awards reaped by individual artists and choral groups from international competitions are there to prove it. The entire nation sings and dances. In any gathering, the fun is doubled if there is karaoke singing. Everyone aspires to win in a singing contest. It is abundantly clear: our hearts are brimming with melodies, which can fill our classroom walls with laughter and songs! The regional rhymes and rhythms can be explored to introduce learners to math wonderland. Table 2 shows a sample list of some of the songs that can brighten a math classroom. Table 2.

THE POWER OF STORYTELLING Children are fond of stories. They love to hear about “the birds and the bees and the flowers and the trees.” What about honeybees and honeycombs? What is it in the hexagonal structure of the mass of wax cells built by honeybees to contain their stores of honey and pollen that makes these winged creatures such remarkable natural optimizers? A fascinating introduction to the language of sizes and geometric shapes is the six-sided honeycomb that allows the maximum space using the least amount of wax. And that is not all there is to the incredible behavior of the honeybees. Aside from their economic instinct, they are also into dance! The waggle dance takes the form of the figure eight and involves angles, lines, distances and cycle lengths. It is an elaborate mode of communication used by honeybees to signal to hivemates the location of food and potential new nesting sites. A role-playing game that calls for the active participation of elementary-age students was designed by Daniel Herms [10], a resident entomologist at a botanical garden. The simulation of the waggle movement affirms that math dance can also raise awareness of the benefits of the foraging foray of bees. Narratives should be harnessed for maximum learning. In the process of telling and re-telling, math concepts can be brought into sharp focus. Take the case of how the Philippine flag came to be. Our national symbol is peppered with geometric shapesequilateral triangle, rectangle, congruent quadrilaterals, three stars equidistant from each other, a circle, eight rays of the sun - and these are replete with significant historical meanings. The account of how our ancestors came up with an efficient system of numeration is riveting. The development of a sophisticated Filipino number sense would captivate kids who grew up playing computer games. Table 3a shows the ancient syllabary equivalent of the numerals (the ten single-digit whole numbers-zero and the first nine counting numbers) as gleaned form Vocabulario de Lengua Tagala: San Buena Ventura 1606 and UST Archivos Libros . Samples of baybayin numerals can be found in the Cave Petroglyphs of Angono, Rizal. Table 3a. Numerals in baybayin form They engaged in barter trade and had a way with ten per cent and large numbers. Table 3b shows the ancient syllabary for ten as a base with negative one as an exponent, and ten raised to the first eight counting numbers. Table 3b. Powers of ten in baybayin SYMBOL 0.1 = 10-1 Daan 1 000 =103 Libo 10 000 = 104 Laksa 100 000 = 105 Yuta 1 000 000 = 106 Angao 10 000 000 = 107 Kati 100 000 000 = 108 Bahala The concept of “powers of 10” lends itself naturally to place values. In Ilocano, what comes after sangapulo (10) is sangapulo ket maysa (10 and 1, or 11). Intuitively, the child knows that 11 consists of a “ten” and a “one”. In sangapulo ket dua or 12, there is a “ten” and two “ones.” Twenty five in Ilocano is duapulo ket lima: 25 is two tens and five ones. Eighty seven is walo pulo ket pito: 87 is eight tens and seven. (This system of counting is similar to how the Chinese and the Laotian languages tackle these numbers.). Primary grade pupils can easily recognize that when all of the ten numerals (corresponding to their ten fingers) have already been exhausted, these can be used again by creating a second column to the left, giving rise to two-digit numbers. The first number that needs the second column is ten, hence such column is called the tens column. The first number that needs the third column is 100, hence that column is referred to as the hundreds column. When the counting gets to the level of 99 (siyam nga pulo ket siyam), that would logically lead to one hundred (sangagasut). The additional columns that are subsequently created correspond to the powers of ten, as reflected it the last three rows of the following matrix of place values. Powers of ten and place values =10 000 Ten thousands 1 Ed Powo 100 = 102 104 Long before foreigners reached the Philippine archipelago, our forefathers had a counting scheme that involved powers of ten Saikapowo 10 = 101 Table 3c.

It never ceases to amaze technology-savvy students that binary arithmetic governs the operation of computers and calculators that have lots of circuits through essentially on/off switches, represented by 1 and 0, respectively. The weaving patterns, music and kinship system of the Kankanaey of Mt. Province (and other regions) can also be tapped as sources of interesting stories that can lead to a deeper understanding of math concepts. Ethnomathematics, the study of the relationship between mathematics and culture. is contextualized learning at its best. 4. GAMES WE USED TO PLAY Psychologists tell us that one way to develop the positive selfworth of children is to encourage them to play. In the words of practicing clinical psychologist and retired professor Dr. Ma. Lordes A. Carandang, “Play helps the child make sense of what is going on in the world. When a child plays, he is able to have a sense of power over his environment and to impose his wishes on his surroundings.” The learners entrusted to our care belong to a generation that has been profoundly shaped by television, computer technology, the Internet, cell phones, iPods, and the phenomenon of OFW parents. They grew up with senses addicted to speed in a distraction-filled environment: blaring frenzied music, video games, Facebook, fast-paced cartoon TV shows, animated movies, reality TV; programs dominated by sex and violence, and accessible unlimited texting – all of which have resulted to shorter attention span. A viable alternative to the sedentary lifestyle spent in front of a TV or computer screen is revisiting indigenous Filipino games that entail muscle memory and develop team spirit, sportsmanship and goodwill. The “Stone Scissors and Paper” game, believed to have originated from the Far East, seems to be well known in various parts of the world. It is commonly called “Jack n Poy” in the Philippines. Two players simultaneously present a hand in one of three positions: an open hand (paper), a closed fist (stone) or two open fingers (scissors). A stone “breaks” scissors, and is paid 2 coins. Paper “covers” stones an is paid 3 coins. Scissors “cut” paper and is paid 4 coins. If both players present the same form, there is a tie, and hence, there is no payoff. As the players try to outguess and outsmart each other, they are initiated into the process of strategic thinking and developing winning strategies. One uniquely Ilocano game is kukudisi. A stick (the an-anak ) is placed on a baseline scratched into the ground. One player makes the stick jump in the air; the other player tries to catch it before it hits the ground. If the latter cannot do so, a second, longer stick (the in-ina ) is laid across the baseline; the player then tries to hit it with the an-anak. The next two phases of the game involve competing to see who can hit the an-anak (which has been tossed in the air and stuck into the baseline, respectively) with the in- ina the farthest. (ww.everyculture.com/wc/Norway-to.../Ilocanos) The mechanics of the game are of course best explained in the mother tongue, to make sure everyone knows the rules for fair Ed play. Table 4 is a list of sample games that can be incorporated in the curriculum. Table 4.

But these can also contribute to the development of creative and critical thinking. Game theory is a relatively new branch of mathematics designed to help people who are in conflict situations to determine the best course of action. The theory does not only govern parlor games, but it has been applied successfully to decision-making problems in economics, business, psychology, sociology warfare and political science. Educationally-rich games that require the animated participation of the entire class will make each child realize that indeed, math is not a spectator sports. People skills, team-player skills and group problem solving skills are some of the highest-level skills that can be sharpened in our children when they are thrown into the arena of games. 5. NATURE AND NURTURE According to National Scientist Dr. Dolores R. Ramirez, an expert in genetics, the inherited aptitude for mathematics is only twelve per cent. (12%). This implies crucial influence educators have in making a difference in math literacy. As W.B. Yeats put it, we need to “light the fire” and provide an enabling environment where the passion for learning can thrive. Children can see a lot more when they survey the world around us with a mathematical eye. To be mathematical means to be curious, open-minded and interested in always learning more. Let us build partnerships and stand in solidarity with our allies in applying the principles of multi-lingual education to help awaken students to the joys of mathematics as the science of patterns. With the heart language, we can entice them into encounters with what they do not yet know about mathematics while honoring and celebrating what they already know. Our task is to equip young people with skills they need to become contributing citizens of the country and to be successful in the world. 6. ACKNOWLEDGEMENT Gratitude is expressed to Engr.
