* Standard Checkers Board: A checkerboard has 64 squares (8 rows x 8 columns).
* Starting Pieces: Each player begins with 12 checkers.
* Total Pieces: There are 24 checkers on the board at the start.
Fraction of Covered Squares:
* (24 checkers) / (64 total squares) = 3/8
Therefore, at the beginning of a checkers game, 3/8 of the squares are covered by checker pieces.
