**Odd Numbers Chart 1 to 100: **An odd number is a whole number that cannot be divided evenly by 2. The last digit of an odd number is always 1, 3, 5, 7, or 9. Because of this, odd numbers can’t be divided evenly into groups of two. When you have an odd number of things, you can’t split them up into equal groups. The number 1 is the only odd number that is also a square number.
