Cebu Province Division

Introduction DAMATH, a patent-pending mathematical board-game invented by five-time national awardee Jesus L. Huenda, is coined from the popular Filipino checkerboard game of dama, (or lady in Spanish) and mathematics. It started in a Sorsogon National High School class in Sorsogon, Philippines and its popularity spread quickly and resulted in the first national DAMATH competitions held at Legaspi City in 1980.

He initiated this competition with the support of the Science Foundation of the Philippines. He hopes to introduce DAMATH to secondary math teachers as part of a requirement of his work as PASMEP Fellow at Curtin University / WACAE, Western Australia.

Thus if this material, or part of it, is used commercially or otherwise (except for classroom instruction purposes), permission must be secured in writing from him. By the way, DAMATH is part of the inventor’s position paper, Non-formal mathematics education: the Sorsogon National High School experience, delivered at the 1978 First Southeast Asian Conference on Mathematical Education, PICC, Manila; 1979 and 1980 MTAP national conventions at Legaspi City and Quezon City, respectively. 1981, 1983 and 1988 Philippine Expositions, PHILTRADE, Manila; conference, Mandurah, WA; Australian Association of Mathematics Teachers 13th biennial national conference, Hobart.

Rationale It is becoming a growing classroom practice in many school subjects, including mathematics, to use games to promote the understanding of concepts and skills. This practice is supported by child psychologist Piaget and Inhelder (1969) and Kohlberg (1969) who are convinced that affective, cognitive, and social development strongly influence one another and develop along parallel lines. There are data to support this statement.

Thus, the use of socially interactive mathematical games in learning and teaching mathematics is credible.

Objectives 1. To integrate the Filipino checkerboard game of dama into the teaching of mathematical concepts and skills. 2. To encourage the utilization of recycled materials in constructing damath board set (for classroom use only). 3. To analyze damath as a possible subject of mathematical investigations. 4. To enhance wholesome interpersonal relations among learners. 5. To promote mathematical consciousness among, family members in particular and the community in general through the mathematics club’s community outreach damath competitions. 6. To promote awareness of girls in mathematics [as king is to the game of chess, so dama (or lady) is to damath ]

Teacher’s Notes:

Any game can be trivial or worthwhile. It all depends on the players of the game and when and why. Feedback from teachers who have tried damath is encouraging because they have found it appropriate, fun, and useful in their classes. All 12 games are to be played in pairs. Students learning mathematics in this way have been found to associate mathematics with wholesome and purposeful work. These games may introduce, supplement, reinforce or refresh concepts, skills and attitudes.

To get the most out of damath, read the accompanying guide sheet and list of materials needed. Determine what extra work can be assigned to pairs of students who will carry out the activity. As a follow-up activity, some mathematical investigations concerning damath may be assigned to small groups of students, or mathematics club may conduct community-outreach damath competitions highlighting awareness of girls in mathematics. In doing so, observe student’s performance and reactions and record them in a cognitive skill checklist and attitude respectively.

This, together with your assessment, will provide you with significant data for future reference. The inventor welcome suggestions from teachers in the field by sending it to: Jesus L. Huenda, Curriculum Development Division, Bureau of Secondary Education, Department of Education, Culture and Sports, Palacio del
Governador, Intramuros, Manila. Suggestions and input can be mailed to him using the following form: (See next page).

TO THE STUDENTS
In DAMATH, there are 12 games to play. All of these games are original especially designed for you – – – to make you do and play mathematics, have fun with it in thinking, making a game plan, and using your common sense, honesty and fair play.

Do them and learn mathematics.

Do them and enjoy yourself, too.

How to make a move
1. Toss a coin to decide who moves first. 2. The first player moves a piece by sliding diagonally forward to an adjoining vacant square (no chip is to
be placed on colored squares). Record your move in the scoresheet. Example: Red player moves “-1” to an adjoining vacant square ( 5 , 4 ), thus, to the scoresheet the player writes on the first column under the heading “Move” with [-1 (5,4) ] to mean “-1” goes to a square located 5 on its x-axis and 4 on its y-axis. 3. The two players alternately take turn in moving a piece.

How to take a piece (Ka-on)
1. In the example above, Red player with piece “-1” is required (pass is not allowed) to take a piece “2” of Blue side by jumping over the piece to be taken and landing on the latter’s adjoining vacant square, which, also, determine the symbol of operation to be used.

Example: “-1” takes “2” by jumping over it (player gets the piece “2”) and finally lands on a square (7,2) which has minus sign on it. Thus, on the scoresheet, the player writes on the first column with “-1 – 2”. Moreover, on the second column under the heading “Score”, the player writes the answer as “-3”. While on the third column under the heading “Total Score”, the player writes the total score by adding whatever points in it, thus, “-3”. Round off numbers, if necessary. 2. A player can take one chip or more than one chip with the required option to take the greater number of chips. 3. A Red chip is declared as “dama” if it reaches any of the following squares: ( 1, 0 ) (3,0) (5,0) (7,0)

Similarly, for Blue Chip as follows: ( 0, 7 ) (2,7) (4,7) (6,7)

4. Once a piece is declared as “dama” it could slide diagonally forward or backward in any vacant square provided no opposing piece blocks it. It could take a piece or pieces and have the privilege of doubling its scores. 5. The game is ended it – – (a.) a player has no more piece to move; or, (b.) it is impossible for any or both players to go on because of repeated move.

General Guidelines on DAMATHS Century Match
1. First player is determined by drawing lots. 2. Basically the rule in playing dama shall be used as follows: a. A “chip with numeral” moves diagonally forward to an adjoining vacant square. b. A chip takes an opponent’s chip or chips diagonally forward or backward.

Mathematical operation such as addition subtraction, multiplication, or division of numerals shall be used depending on the vacant square’s operation symbol where the “taker” chip lands by jumping over the “taken” chip, “pass” is not allowed. c. On taking a chip or chips the following policy shall prevail: * “mayor dalawa” * “mayor tatlo” * “mayor dama” * “mayor dama dalawa” (x) takes 0 VS (x) takes 0 VS (x) takes 0 VS (dama) takes 0 (y) takes 1, takes 2 (y) takes 1, takes 2, and takes 3 (dama) takes 1 VS (x) takes 1, takes 2 over mayor dama.

d. A player’s chip is declared as “dama” if it reaches the other player’s designated “dama” locations or squares. A dama chip can move or take a piece to any unoccupied square along the diagonal path. Moreover, when a “dama” takes a chip the score is doubled; when the “dama” is taken the score is also doubled; when a “dama” takes another “dama” the score is quadrupled. e. In taking more than one chip, the “taker” chip shall remain as the initial addend, minuend, multiplicand, or dividend as the case maybe.

(This means that MDAS for multiple operations shall not apply in this case). f. A “move” is good only for one (1) minute, while the game’s duration shall not exceed 20 minutes. g. The remaining chips shall be added to the respective players. h. The game ends when any one of the following situations occur:
