Summary
In
this section you looked at sets of people, things,
and dots. You tried to make as may pairs as
possible.
Sometimes
you could fill the set completely with pairs.
Sometimes one "thing" was left. This
led to thinking about even and odd number sand
how they are different.
Even
and odd numbers can help you understand something
about patterns. For example, V-patterns are
described by odd numbers.
