Example Question #9 : Determine Even Or Odd Number Of Objects: Ccss.Math.Content.2.Oa.C.3
Is there an even or an odd number of dots below?
Both
Neither
Odd
Even
Even
When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, our dots are in pairs of two, so we have an even number of dots.

When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.
In this case, we have one dot not in a pair, so we have an odd number of dots.
