Division is the process of splitting a number into equal groups. When you divide a number by 1, the number stays the same because you are only making one group.
Dividing by 1 does not change the number. You are placing all of the objects into a single group.
Any number divided by 1 equals itself because all of the objects are kept together in one whole group. Nothing is split apart.
Think of it this way: dividing by 1 means, “How many are in one group?” The answer is always the original number.
Here is a list of division facts when dividing by 1. Memorizing these facts helps build speed and confidence in solving math problems.
Knowing these facts prepares you for more challenging division problems, including dividing by larger numbers.
Division by 1 can be seen in everyday life when items are kept together instead of being split into smaller groups.
Recognizing division by 1 in real-life situations helps make the math fact more meaningful and easier to remember.
