The main advantages are that children become familiar with using numbers to
relate to position on a page – just like in computer programming.
For example Scratch's coordinate system uses 2 coordinates, "X position" and "Y position", to
determine the location of a sprite on the stage. The "X position" value determines the horizontal
location of the sprite and the "Y position" value determines the vertical location or height. The
screen is a 480x360 rectangle, such that: the X position can range from 240 to -240, where 240 is
the rightmost a sprite can be and -240 is the leftmost, and the Y position can range from 180 to
-180, where 180 is the highest it can be and -180 is the lowest it can be.
Coordinates are, by convention, written as a pair (X, Y):
for example, the centre of the screen is (0, 0).
They also begin to develop and modify a simple linear search strategy into something far more
effective. I have found that, through playing these sorts of games, people begin to use far more
logical thought processes and the more they play, the easier it is and the better they become.
