1.2 Prime and Composite Numbers
 A number with only two factors, 1 and itself, is called a
prime #
________________________.
 A number with more than two factors is called a
composite #
_______________________.
 The #1 is special because it only has one factor. Therefore, it is
neither
________________________ prime nor composite.
choosing the number 1 will make you lose
your turn because it has no proper factors
it’s better to choose the largest prime number
as your first move since it will give you the
most points and your opponent the least

prime #s
 ______________________ only have one proper factor, but
composite #s
_________________________ have more than one proper factor.
 Choosing any prime number will only give your opponent 1 point,
but choosing the highest prime number as your first move on any
game board is the best move because it will give you the most
points and your opponent the least.
 Choosing a composite number as a first move isn’t necessarily a bad
move, unless it has many factors or the sum of the factors is greater
than the number you chose.
 It’s best to choose numbers with only 2 or 3 factors so that your
opponent will score fewer points than you.
