| dice |
Dice are things that we use when we play some kinds of games. Dice are often made out of wood or other hard material, and they have the shape of little boxes with square sides. Each of these sides has from one to six dots on it. In games, we throw the dice and see what number of dots appear when the dice stop moving. |
| difference |
If one number is bigger or smaller than another number, then there is a difference between them. Six is bigger than four, and the difference between the numbers is two. Four is smaller than six, and the difference, again, is two. The difference between two numbers is how much bigger or smaller one is than the other. [1/2 definitions] |

A digit is any of the numbers from zero through nine. These digits--0, 1, 2, 3, 4, 5, 6, 7, 8, and 9--are also used when we write bigger numbers. For example, the number 125 uses three digits. It uses the digits 1, 2, and 5. We call a number like 125 a "three-digit number." [1/2 definitions] |

| division sign |
One action we do with numbers is to divide one number by another. An example of dividing is "six divided by two equals three." When we write this in numbers, we use something called a division sign (÷) between the first two numbers: 6 ÷ 2. The division sign looks like a short little line with one dot above it and one dot below it. When we see a division sign between two numbers, it tells us that the first number is being divided by the second number. |
