Math Game


Damath is a board game that comes from the Philippines, and is used as a teaching tool for high school mathematics.
The game's name, “Damath,” comes from the popular board game “dama” and “mathematics.” It was invented by Jesus L. Huenda, a teacher in Sorsogon, who had encountered problems in teaching math using traditional teaching methods. Inspired in part by an investigatory project called “Dama de Numero” submitted by a student in 1975, Huenda overhauled the game and introduced it to his class, who enjoyed playing.
Damath grew in popularity so that by 1980, the first Damath tournament was held in Sorsogon. The next year, Huenda received a gold medallion from the late President Ferdinand Marcos for his contributions in the field of teaching mathematics.The game reached its peak popularity in the 1990s, when it made the rounds of several mathematics education conventions all over the world such as the 10th Conference of the Mathematical Association of Western Australia (MAWA), the UNESCO-ICT4E conference in Thailand, the SEAMEO RECSAM/SEAMEC conference in Malaysia, and the APEC Learning Community Builders (ALCoB) conference in Korea.

The BoardThe Damath board, similar to a chess board, consists of 8 x 8 squares alternating in black and white. On the white squares are the four basic Mathematical operations--addition, subtraction, multiplication and divisionThere are two sets of twelve pieces for each player, marked with numbers from zero to eleven. Odd numbers are marked with negative signs and placed on the left side of the board while even numbers are positive and placed on the right. Numbers outside the playing squares act as guides to show the correct positioning of the pieces.  Basic GameplayAs the name implies, the game is essentially the same as dama but with an added math twist: in order to win in Damath, a player must score the most points which are earned by “eating” the opponent's pieces. In dama, the move ends there; in Damath, the player must solve the mathematical operation on the square in which the opponents piece is currently standing. The answer to that mathematical operation is the amount of points that the player will receive when s/he does “eat” the opponent's piece.If the piece marked “-1” eats the piece marked “-3,” with “-3” standing on a multiplication square, the player must first solve the operation (-1 x -3 = 3) and will get three points. The game will go on until all pieces belonging to a player have been eaten and the scores computed.Because of the need to solve operations, players must list down all moves during the game so the moves can be reviewed, especially by the judges in a tournament setting.http://en.wikipilipinas.org/index.php?title=Damath



Math Terms

Acute angle – An angle which measures below 90°.
Acute triangle – A triangle containing only acute angles.
Additive inverse – The opposite of a number or its negative. A number plus its additive inverse equals 0.
Adjacent angles – Angles with a common side and vertex.
Angle – Created by two rays and containing an endpoint in common.
Arc – A set of points that lie on a circle and that are positioned within a central angle.
Area – The space contained within a shape.
Average – The numerical result of dividing the sum of two or more quantities by the number of quantities.
Binomial – An expression in algebra that consists of two terms.
Bisect – To divide into two equal sections.
Canceling – In multiplication of fractions, when one number is divided into both a numerator and a denominator.
Cartesian coordinates – Ordered number pairs that are assigned to points on a plane.
Chord – A line segment that connects two points on a circle.
Circle – A set of points that are all the same distance from a given point.
Circumference – The distance measured around a circle.
Coefficient – A number that is placed in front of a variable. For example, in 6x, 6 is the coefficient.
Common denominator – A number that can be divided evenly by all denominators in the problem.
Complementary angles – Two angles in which the sum of their measurements equals 90°.
Complex fraction – A fraction that contains a fraction or fractions in the numerator and/or denominator.
Congruent – Exactly the same. Identical in regard to size and shape.
Coordinate graph – Two perpendicular number lines, the x axis and the y axis, which make a plane upon which each point is assigned a pair of numbers.
Cube – A solid with six sides, with the sides being equal squares and the edges being equal. Also, the resulting number when a number is multiplied by itself twice.
Cube root – A number that when multiplied by itself twice gives the original number. For example, 4 is the cube root of 64.
Decimal fraction – Fraction with a denominator of 10, 100, 1,000, etc., written using a decimal point.
Degree – The measurement unit of an angle.
Denominator – The bottom symbol or number of a fraction.
Diameter – A line segment that contains the center and has its endpoints on the circle. Also, the length of this segment.
Difference – That which results from subtraction.

LITTLE BOOTS LYRICS

"Mathematics"



Mathematics is a difficult thing
I never understood what was the missing link
And by the time I'd calculated the correct solution
The question had escaped me and so did the conclusion

So tell me, everything must always be for two
Or nothing else is true and I'll believe you
Cos your X is equal to my Y but equations pass me by

So will you take just a little of my mind
And subtract it by my soul 
Add a fraction of your heart
And you'll see it makes me whole
Multiply it by the times that we've never been apart
You'll see nothing can divide just a heart plus a heart
A little of my mind
Take it from my soul
A fraction of your heart 
See it makes me whole
And multiply the times, we'll never be apart 
Cos nothing can divide a heart plus a heart

Don't know my Fibonacci or Pythagoras
But the only formula I know will work for us
Is that when we're together in the sum of our parts
It's more greater than what we added up to at the start

So tell me, everything must always be for two
Or nothing else is true and I'll believe you
Cos your X is equal to my Y but equations pass me by

So will you take just a little of my mind
And subtract it by my soul 
Add a fraction of your heart
And you'll see it makes me whole
Multiply it by the times that we've never been apart
You'll see nothing can divide just a heart plus a heart
A little of my mind
Take it from my soul
A fraction of your heart 
See it makes me whole
And multiply the times, we'll never be apart 
Cos nothing can divide a heart plus a heart
A heart plus a heart

Take just a little of my mind
And subtract it by my soul
Add a fraction of your heart
And you'll see it makes me whole
Multiply it by the times that we've never been apart
You'll see nothing can divide just a heart plus a heart

A little of my mind
Take it from my soul
A fraction of your heart 
See it makes me whole
And multiply the times, we'll never be apart 
Cos nothing can divide a heart plus a heart

Math Puzzle

Jumping puzzle

These mazes are based on the idea that you can jump the specified number of steps in any direction, horizontally or vertically.Here's a simple example. Start at the 2 in the top left-hand corner, and find a route to the 1 in the bottom right-hand corner:NumberFrom the starting square you can move right to the 0 in the top row, or down to the 1 in the leftmost column. Then from the 1 you can move up to the 0 above it, or right to the 2 in the bottom row, and so on. Here's the full six-step solution:Numberhttp://www.mazelog.com/show?7
