Each player draws 4 blank lines on a
sheet of paper to record the numbers that come up on the rolls of the
die.

Player A rolls the die and writes the
number on any one of his or her 4 blanks. It does not have to be
the first blank--it can be any of them. Keep in mind that the
larger number wins! Then Player B rolls the die and writes the
number on one of his or her blanks.
Players take turns doing this 3 more times
each.
Each player then uses the 4 numbers on his
or her blanks to build a number. The numbers on the first 3 blanks
are the first 3 digits of the number the player builds. The number
on the 4th blank tells the number of zeros that come after the first 3
digits. Each player reads his or her number. The player with
the larger number wins the round.
