Question

Is there an even or an odd number of dots below?

Screen shot 2015 12 01 at 10.42.14 am

Answer

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. This dot is not in a pair, so we have an odd number of dots.
