In mathematical terms, a “unit” refers to an individual thing or a complete single entity. It can also mean the rightmost number found in the ones place.

A unit is something that is one complete thing by itself or is one piece of a whole or group. Look at the picture above. Each cube is one unit by itself, but each unit is also a part of a group of 3. If you take 1 unit away, it becomes a group of 2 units. The individual units stay the same, but the group has changed size. See the picture below.

Often a unit in math refers to the number 1. For example, how many units does it take to make a group of 10? Did you say 10? You’re right!
